1 Safety information

1.1 Warnings, Cautions and Notes

A Warning contains information which is essential for avoiding a safety hazard.

A Caution contains information which is necessary for avoiding a risk of damage to the product or other equipment.

A Note contains information which helps to ensure correct operation of the product.

1.2 Important safety information. Hazards.

This guide applies to products which control electric motors either directly (drives) or indirectly (controllers, option modules and other auxiliary equipment and accessories). In all cases the hazards associated with powerful electrical drives are present, and all safety information relating to drives and associated equipment must be observed.

Specific warnings are given at the relevant places in this guide.

Drives and controllers are intended as components for professional incorporation into complete systems. If installed incorrectly they may present a safety hazard. The drive uses high voltages and currents, carries a high level of stored electrical energy, and is used to control equipment which can cause injury. Close attention is required to the electrical installation and the system design to avoid hazards either in normal operation or in the event of equipment malfunction. System design, installation, commissioning/start-up and maintenance must be carried out by personnel who have the necessary training and competence. They must read this safety information and this guide carefully.

1.3 Responsibility

It is the responsibility of the installer to ensure that the equipment is installed correctly with regard to all instructions given in this guide. They must give due consideration to the safety of the complete system, so as to avoid the risk of injury both in normal operation and in the event of a fault or of reasonably foreseeable misuse.

The manufacturer accepts no liability for any consequences resulting from inappropriate, negligent or incorrect installation of the equipment.

1.4 Compliance with regulations

The installer is responsible for complying with all relevant regulations, such as national wiring regulations, accident prevention regulations and electromagnetic compatibility (EMC) regulations. Particular attention must be given to the cross-sectional areas of conductors, the selection of fuses or other protection, and protective ground (earth) connections.

This guide contains instructions for achieving compliance with specific EMC standards.

All machinery to be supplied within the European Union in which this product is used must comply with the following directives:

2006/42/EC Safety of machinery.

2014/30/EU: Electromagnetic Compatibility.

Competence of designers and installers

1.5 Electrical hazards

The voltages used in the drive can cause severe electrical shock and/or burns, and could be lethal. Extreme care is necessary at all times when working with or adjacent to the drive. Hazardous voltage may be present in any of the following locations:

• AC and DC supply cables and connections

• Output cables and connections

• Many internal parts of the drive, and external option units

Unless otherwise indicated, control terminals are single insulated and must not be touched.

The supply must be disconnected by an approved electrical isolation device before gaining access to the electrical connections.

The STOP and Safe Torque Off functions of the drive do not isolate dangerous voltages from the output of the drive or from any external option unit.

The drive must be installed in accordance with the instructions given in this guide. Failure to observe the instructions could result in a fire hazard.

1.6 Stored electrical charge

The drive contains capacitors that remain charged to a potentially lethal voltage after the AC supply has been disconnected. If the drive has been energized, the AC supply must be isolated at least ten minutes before work may continue.

1.7 Mechanical hazards

Careful consideration must be given to the functions of the drive or controller which might result in a hazard, either through their intended behaviour or through incorrect operation due to a fault. In any application where a malfunction of the drive or its control system could lead to or allow damage, loss or injury, a risk analysis must be carried out, and where necessary, further measures taken to reduce the risk - for example, an over-speed protection device in case of failure of the speed control, or a fail-safe mechanical brake in case of loss of motor braking.

With the sole exception of the Safe Torque Off function, none of the drive functions must be used to ensure safety of personnel, i.e. they must not be used for safety-related functions.

The Safe Torque Off function may be used in a safety-related application. The system designer is responsible for ensuring that the complete system is safe and designed correctly according to the relevant safety standards.

The design of safety-related control systems must only be done by personnel with the required training and experience. The Safe Torque Off function will only ensure the safety of a machine if it is correctly incorporated into a complete safety system. The system must be subject to a risk assessment to confirm that the residual risk of an unsafe event is at an acceptable level for the application.

1.8 Access to equipment

Access must be restricted to authorized personnel only. Safety regulations which apply at the place of use must be complied with.

1.9 Environmental limits

Instructions in this guide regarding transport, storage, installation and use of the equipment must be complied with, including the specified environmental limits. This includes temperature, humidity, contamination, shock and vibration. Drives must not be subjected to excessive physical force.

1.10 Hazardous environments

The equipment must not be installed in a hazardous environment (i.e. a potentially explosive environment).

1.11 Motor

The safety of the motor under variable speed conditions must be ensured.

To avoid the risk of physical injury, do not exceed the maximum specified speed of the motor.

Low speeds may cause the motor to overheat because the cooling fan becomes less effective, causing a fire hazard. The motor should be installed with a protection thermistor. If necessary, an electric forced vent fan should be used.

The values of the motor parameters set in the drive affect the protection of the motor. The default values in the drive must not be relied upon. It is essential that the correct value is entered in the Motor Rated Current parameter.

1.12 Mechanical brake control

Any brake control functions are provided to allow well co-ordinated operation of an external brake with the drive. While both hardware and software are designed to high standards of quality and robustness, they are not intended for use as safety functions, i.e. where a fault or failure would result in a risk of injury. In any application where the incorrect operation of the brake release mechanism could result in injury, independent protection devices of proven integrity must also be incorporated.

1.13 Adjusting parameters

Some parameters have a profound effect on the operation of the drive. They must not be altered without careful consideration of the impact on the controlled system. Measures must be taken to prevent unwanted changes due to error or tampering.

2.3 Ratings

The size 1 to 4 drive is Heavy Duty rated only. The size 5 to 9 drive is dual rated. The setting of the motor rated current determines which rating applies Heavy Duty or Normal Duty. The two ratings are compatible with motors designed to IEC60034. The graph aside illustrates the difference between Normal Duty and Heavy Duty with respect to continuous current rating and short term overload limits.

Normal Duty Heavy Duty (default)

For applications which use Self ventilated (TENV/TEFC) induction motors and require a low overload capability, and full torque at low speeds is not required (e.g. fans, pumps). Self ventilated (TENV/TEFC) induction motors require increased protection against overload due to the reduced cooling effect of the fan

at low speed. To provide the correct level of protection the I

t software operates at a level which is speed dependent. This is illustrated in the graph below.

The speed at which the low speed protection takes effect can be changed by the setting of Low Speed Thermal Protection Mode (04.025). The protection starts when the motor speed is below 15 % of base speed when Pr 04.025 = 0 (default) and below 50 % when Pr 04.025 = 1.

Operation of motor I2t protection

Motor I2t protection is fixed as shown below and is compatible with:

• Self ventilated (TENV/TEFC) induction motors

For constant torque applications or applications which require a high overload capability, or full torque is required at low speeds (e.g. winders, hoists). The thermal protection is set to protect force ventilated induction motors by default.

If the application uses a self ventilated (TENV/TEFC) induction motor and increased thermal protection is required for speeds below 50 % base speed, then this can be enabled by setting Low Speed Thermal Protection Mode (04.025) = 1.

Motor I2t protection defaults to be compatible with:

• Forced ventilation induction motors

2.4 Operating modes

The drive is designed to operate in any of the following modes:

1. Open loop mode Open loop vector mode Fixed V/F mode (V/Hz) Square V/F mode (V/Hz)

2. RFC - A

Without position feedback sensor

2.4.1 Open loop mode

The drive applies power to the motor at frequencies varied by the user. The motor speed is a result of the output frequency of the drive and slip due to the mechanical load. The drive can improve the speed control of the motor by applying slip compensation. The performance at low speed depends on whether V/F mode or open loop vector mode is selected.

Open loop vector mode

The voltage applied to the motor is directly proportional to the frequency except at low speed where the drive uses motor parameters to apply the correct voltage to keep the flux constant under varying load conditions.

Typically 100 % torque is available down to 1 Hz for a 50 Hz motor.

Fixed V/F mode

The voltage applied to the motor is directly proportional to the frequency except at low speed where a voltage boost is provided which is set by the user. This mode can be used for multi-motor applications.

Typically 100 % torque is available down to 4 Hz for a 50 Hz motor.

Square V/F mode

The voltage applied to the motor is directly proportional to the square of the frequency except at low speed where a voltage boost is provided which is set by the user. This mode can be used for running fan or pump applications with quadratic load characteristics or for multi-motor applications. This mode is not suitable for applications requiring a high starting torque.

2.4.2 RFC-A mode

Rotor Flux Control for Asynchronous (induction) motors (RFC-A) encompasses closed loop vector control without a position feedback device

Rotor flux control provides closed loop control without the need for position feedback by using current, voltages and key motor parameters to estimate the motor speed. It can eliminate instability traditionally associated with open loop control for example when operating large motors with light loads at low frequencies.

2.5 Keypad and display

The keypad and display provide information to the user regarding the operating status of the drive and trip codes, and provide the means for changing parameters, stopping and starting the drive, and the ability to perform a drive reset.

4.1 24 Vdc supply

The 24 Vdc supply connected to the +24 V supply terminals on the AIBackup adaptor provides the following functions:

• It can be used as a back-up power supply to keep the control circuits

of the drive powered up when the line power supply is removed. This allows any fieldbus modules or serial communications to continue to operate. If the line power supply is re-applied, then the normal operation can carry on after the drive automatically re-initializes the power board parameters.

• It can be used to clone or load parameters in order to pre-configure

drives when the line power supply is not available. The keypad can be used to setup parameters if required. However, the drive will be in the Under Voltage state unless the line power supply is enabled, therefore diagnostics may not be possible. (Power down save parameters are not saved when using the 24 V back-up power supply input).

The working voltage range of the 24 V back-up power supply is as follows:

0 V (connected internally to 0V common - Control

0 V

terminal 1)

+ 24 V + 24 V Backup supply input

Nominal operating voltage 24.0 Vdc

Minimum continuous operating voltage 19.2 V

Maximum continuous operating voltage 30.0 V

Minimum start up voltage 12.0 V

Minimum power supply requirement at 24 V 20 W

Maximum power supply continuous current 3 A

Recommended fuse 1 A, 50 Vdc

Minimum and maximum voltage values include ripple and noise. Ripple and noise values must not exceed 5 %.

Figure 4-1 Location of the 24 Vdc power supply connection on the

AI-Backup adaptor

4.2 Communication connections

Installing an AI-485 Adaptor provides the drive with a 2 wire EIA-485 serial communications interface. This enables the drive set-up, operation and monitoring to be carried out with a PC or controller as required.

Figure 4-2 Location of the AI-485 Adaptor option

4.2.1 EIA 485 serial communications

The drive only supports Modbus RTU protocol. See Table 4-1 for the connection details.

Standard Ethernet cables must not be used when connecting drives on a EIA 485 network as they do not have the correct twisted pairs for the pinout of the serial comms port.

4.2.2 Isolation of the EIA 485 serial communication

port

The serial communication port is single insulated and meets the requirements for ELV.

When using the communications port with a personal computer or centralised controller e.g. PLC, an isolation device must be included with a rated voltage at least equal to the drive supply voltage. Ensure that the correct fuses are installed at the drive input, and that the drive is connected to the correct supply voltage. If a serial communications converter other than the CT Comms cable is used to connect to other circuits classified as Safety Extra Low Voltage (SELV) (e.g. to a personal computer), then a safety isolating barrier must be included to maintain the SELV classification.

An isolated serial communications lead has been designed to connect the drive to IT equipment (such as laptop computers), and is available from the supplier of the drive. See below for details:

Table 4-3 Isolated serial comms lead details

Part number Description

4500-0096 CT USB Comms cable

The “isolated serial communications” lead has reinforced insulation as defined in IEC60950 for altitudes up to 3,000 m.

The control circuits are isolated from the power circuits in the drive by basic insulation (single insulation) only. The installer must ensure that the external control circuits are insulated from human contact by at least one layer of insulation (supplementary insulation) rated for use at the AC supply voltage.

If the control circuits are to be connected to other circuits classified as Safety Extra Low Voltage (SELV) (e.g. to a personal computer), an additional isolating barrier must be included in order to maintain the SELV classification.

If any of the digital inputs (including the drive enable input) are connected in parallel with an inductive load (i.e. contactor or motor brake) then suitable suppression (i.e. diode or varistor) should be used on the coil of the load. If no suppression is used then over voltage spikes can cause damage to the digital inputs and outputs on the drive.

Any signal cables which are carried inside the motor cable (i.e. motor thermistor, motor brake) will pick up large pulse currents via the cable capacitance. The shield of these signal cables must be connected to ground close to the point of exit of the motor cable, to avoid this noise current spreading through the control system.

Figure 5-4 Mode examples

1 Parameter view mode: Read write or Read only

2 Status mode: Drive OK status

If the drive is ok and the parameters are not being edited or viewed, the display will show one of the following:

inh', 'rdy' or status mode parameter value.

3 Status mode: Trip status When the drive is in trip condition, the display will indicate that the drive has tripped and the display will show the trip code. For further information regarding trip codes, refer to section 12.4 Trips, Sub-trip numbers on page 130.

4 Status mode: Alarm status During an 'alarm' condition the display flashes between the drive status parameter value and the alarm.

5.3 Menu structure

The drive parameter structure consists of menus and parameters.

The drive initially powers up so that only Menu 0 can be viewed. The up and down arrow buttons are used to navigate between parameters and once Pr 10 has been set to 'All' the up and down buttons are used to navigate between menus.

For further information refer to section 5.9 Parameter access level and security on page 27.

The menus and parameters rollover in both directions i.e. if the last parameter is displayed, a further press will cause the display to rollover and show the first parameter.

When changing between menus, the drive remembers which parameter was last viewed in a particular menu and thus displays that parameter.

5.4 Menu 0

Menu 0 is used to bring together various commonly used parameters for basic easy set up of the drive. The parameters displayed in Menu 0 can be configured in Menu 22. Appropriate parameters are copied from the advanced menus into Menu 0 and thus exist in both locations.

For further information, refer to Chapter 6 Basic parameters on page 29.

Figure 5-5 Menu 0 copying

Do not change parameter values without careful consideration; incorrect values may cause damage or a safety hazard.

When changing the values of parameters, make a note of the new values in case they need to be entered again.

New parameter values must be saved to ensure that the new values apply after the drive has been power cycled. Refer to section 5.7 Saving parameters on page 26.

The keypad remains in status mode and only first 10 parameters in Menu 0 can be viewed or edited.

The keypad remains in status mode and only first 10

no.Acc (4)

parameters in Menu 0 can be viewed or edited. Drive parameters cannot be accessed via a comms interface.

5.9.2 Changing the User Security Level /Access Level

The security level is determined by the setting of Pr 10 or Pr 11.044. The Security Level can be changed through the keypad even if the User Security Code has been set.

5.9.3 User Security Code

The User Security Code, when set, prevents write access to any of the parameters in any menu.

Setting User Security Code

Enter a value between 1 and 9999 in Pr 25 and press the button; the security code has now been set to this value. In order to

activate the security, the Security level must be set to desired level in Pr 10. When the drive is reset, the security code will have been activated and the drive returns to LEVEL.1. The value of Pr 25 will return to 0 in order to hide the security code.

Unlocking User Security Code

Select a parameter that need to be edited and press the button, the display will now show ‘Co’. Use the arrow buttons to set the security

code and press the button. With the correct security code entered, the display will revert to the parameter selected in edit mode.

If an incorrect security code is entered, the following message ‘Co.Err’ is displayed, and the display will revert to parameter view mode.

Disabling User Security

Unlock the previously set security code as detailed above. Set Pr 25 to 0

and press the button. The User Security has now been disabled, and will not have to be unlocked each time the drive is

powered up to allow read / write access to the parameters.

5.10 Displaying parameters with non-

default values only

By selecting 'diff.d' in Pr 00 (Alternatively, enter 12000 in Pr 00), the only parameters that will be visible to the user will be those containing a non-default value. This function does not require a drive reset to become active. In order to deactivate this function, return to

Pr 00 and select 'none' (alternatively enter a value of 0). Please note that this function can be affected by the access level enabled, refer to section

5.9 Parameter access level and security on page 27 for further

information regarding access level.

Please note that this function can be affected by the access level enabled, refer to section 5.9 Parameter access level and security on page 27 for further information regarding access level.

5.12 Communications

Installing an AI-485 Adaptor provides the drive with a 2 wire EIA 485 serial communications interface. This enables the drive set-up, operation and monitoring to be carried out with a PC or controller as required.

5.12.1 EIA 485 Serial communications

Communication is via the RJ45 connector or screw terminals (parallel connection). The drive only supports Modbus RTU protocol.

The communications port applies a 1.25 unit load to the communications network.

USB to EIA 485 Communications

An external USB hardware interface such as a PC cannot be used directly with the 2-wire EIA 485 interface of the drive. Therefore a suitable converter is required.

A suitable USB to EIA 485 isolated converter is available from Control Techniques as follows:

• CT USB Comms cable (CT Part No. 4500-0096)

When using the above converter or any other suitable converter with the drive, it is recommended that no terminating resistors be connected on the network. It may be necessary to 'link out' the terminating resistor within the converter depending on which type is used. The information on how to link out the terminating resistor will normally be contained in the user information supplied with the converter.

Serial communications set-up parameters

The following parameters need to be set according to the system requirements.

Serial Mode

The drive only supports the Modbus RTU protocol and is always a slave. This parameter defines the supported data formats used by the EIA 485 comms port (if installed) on the drive. This parameter can be changed via the drive keypad, via a option module or via the comms interface itself.

7 1 EP (8), 7 1 OP (9), 7 1 EP M (10), 7 1 OP M (11)

600 (1), 1200 (2), 2400 (3), 4800 (4), 9600 (5), 19200 (6), 38400 (7),

This parameter can be changed via the drive keypad, via a option module or via the comms interface itself. If it is changed via the comms interface, the response to the command uses the original baud rate. The master should wait at least 20 ms before sending a new message using the new baud rate.

57600(8), 76800(9), 115200 (10)

7 Running the motor

This chapter takes the new user through all the essential steps to running a motor for the first time, in each of the possible operating modes.

For information on tuning the drive for the best performance, see Chapter 8 Optimization on page 48.

Ensure that no damage or safety hazard could arise from the motor starting unexpectedly.

The values of the motor parameters affect the protection of the motor. The default values in the drive should not be relied upon. It is essential that the correct value is entered in Pr 06 Motor Rated Current. This affects the thermal protection of the motor.

If the drive is started using the keypad it will run to the speed defined by the keypad reference (Pr 01.017). This may not be acceptable depending on the application. The user must check in Pr 01.017 and ensure that the keypad reference has been set to 0.

If the intended maximum speed affects the safety of the machinery, additional independent over-speed protection must be used.

7.2 Changing the operating mode

Procedure

Use the following procedure only if a different operating mode is required:

1. Ensure that the drive is not enabled, i.e. drive is in inhibit or under voltage state.

2. Change the setting of Pr 79 as follows:

Pr 79 setting Operating mode

1 Open-loop

2RFC-A

The figures in the second column apply when serial communications are used.

3. Either:

• Press the red reset button

• Carry out a drive reset through serial communications by setting Pr 10.038 to 100.

When the operating mode is changed, a parameter save is carried out.

7.1 Quick start connections

7.1.1 Basic requirements

This section shows the basic connections which must be made for the drive to run in the required mode. For minimal parameter settings to run in each mode please see the relevant part of section 7.3 Quick start commissioning / start-up on page 46.

The drive is able to perform either a stationary or a rotating autotune. The motor must be at a standstill before an autotune is enabled. A rotating autotune should be used whenever possible so the measured value of power factor of the motor is used by the drive.

• A stationary autotune can be used when the motor is loaded and it is not possible to uncouple the load from the motor shaft. A stationary autotune measures the stator resistance of the motor and the dead time compensation for the drive. These are required for good performance in vector control modes. A stationary autotune does not measure the power factor of the motor so the value on the motor nameplate must be entered into Pr 09.

• A rotating autotune should only be used if the motor is uncoupled. A rotating autotune first performs a stationary autotune before rotating the motor at

/3 base speed in the direction selected. The

rotating autotune measures the power factor of the motor.

To perform an autotune:

•Set Pr 38 = 1 for a stationary autotune or set Pr 38 = 2 for a rotating autotune

• Close the Drive Enable signal (apply +24 V to terminal 11). The drive will display ’rdy’.

• Give a run command (apply +24 V to terminal 12 - Run forward or terminal 13 - Run reverse on Unidrive M200; press keypad start button on M201). The display will flash ’tuning’ while the drive is performing the autotune.

• Wait for the drive to display ‘inh’ and for the motor to come to a standstill.

If the drive trips, see Chapter 12 Diagnostics on page 129.

• Remove the drive enable and run signal from the drive.

Select 'Save' in Pr 00 or Pr mm.000 (alternatively enter a value of 1001) and press the red reset button.

The drive is able to perform either a stationary or a rotating autotune. The motor must be at a standstill before an autotune is enabled. A stationary autotune will give moderate performance whereas a rotating autotune will give improved performance as it measures the actual values of the motor parameters required by the drive.

• A stationary autotune can be used when the motor is loaded and it is not possible to uncouple the load from the motor shaft. The stationary autotune measures the stator resistance and transient inductance of the motor. These are used to calculate the current loop gains, and at the end of the test the values in Pr 04.013 and Pr 04.014 are updated. A stationary autotune does not measure the power factor of the motor so the value on the motor nameplate must be entered into Pr 09.

• A rotating autotune should only be used if the motor is uncoupled. A rotating autotune first performs a stationary autotune before rotating the motor at

/3 base speed in the direction selected. The rotating

autotune measures the stator inductance of the motor and calculates the power factor.

To perform an autotune:

•Set Pr 38 = 1 for a stationary autotune or set Pr 38 = 2 for a rotating autotune

• Close the drive enable signal (apply +24 V to terminal 11). The drive will display ’rdy’.

8 Optimization

This chapter takes the user through methods of optimizing the drive set-up and maximize the performance. The auto-tuning features of the drive simplify the optimization tasks.

8.1 Motor map parameters

8.1.1 Open loop motor control

Pr 06 {05.007} Motor Rated Current Defines the maximum continuous motor current

• The rated current parameter must be set to the maximum continuous current of the motor. The motor rated current is used in the following:

• Current limits (see section section 8.3 Current limits on page 54, for more information)

• Motor thermal overload protection (see section section 8.4 Motor thermal protection on page 54, for more information)

• Vector mode voltage control (see Control Mode later in this table)

• Slip compensation (see Enable Slip Compensation (05.027), later in this table)

• Dynamic V/F control

Pr 08 {05.009} Motor Rated Voltage Defines the voltage applied to the motor at rated frequency

Pr 39 {05.006} Motor Rated Frequency Defines the frequency at which rated voltage is applied

The Motor Rated Voltage (Pr 08) and the Motor Rated Frequency (Pr 39) are used to define the voltage to frequency characteristic applied to the motor (see Control Mode, later in this table). The Motor Rated Frequency is also used in conjunction with the motor rated speed to calculate the rated slip for slip compensation (see Motor Rated Speed, later in this table).

Pr 07 {05.008} Motor Rated Speed Defines the full load rated speed of the motor

Pr 40 {05.011} Number of Motor Poles Defines the number of motor poles

The motor rated speed and the number of poles are used with the motor rated frequency to calculate the rated slip of induction machines in Hz.

Rated slip (Hz) = Motor rated frequency - (Number of pole pairs x [Motor rated speed / 60]) =

If Pr 07 is set to 0 or to synchronous speed, slip compensation is disabled. If slip compensation is required this parameter should be set to the nameplate value, which should give the correct rpm for a hot machine. Sometimes it will be necessary to adjust this when the drive is commissioned because the nameplate value may be inaccurate. Slip compensation will operate correctly both below base speed and within the field-weakening region. Slip compensation is normally used to correct for the motor speed to prevent speed variation with load. The rated load rpm can be set higher than synchronous speed to deliberately introduce speed droop. This can be useful to aid load sharing with mechanically coupled motors.

Pr 40 is also used in the calculation of the motor speed display by the drive for a given output frequency. When Pr 40 is set to ‘Auto’, the number of motor poles is automatically calculated from the rated frequency Pr 39, and the motor rated speed Pr 07.

Number of poles = 120 x (Rated Frequency (Pr 39) / Rated Speed (Pr 07)) rounded to the nearest even number.

Pr 43 {05.010} Motor Rated Power Factor Defines the angle between the motor voltage and current

The power factor is the true power factor of the motor, i.e. the angle between the motor voltage and current. The power factor is used in conjunction with the Motor Rated Current (Pr 06), to calculate the rated active current and magnetising current of the motor. The rated active current is used extensively to control the drive, and the magnetising current is used in vector mode stator resistance compensation. It is important that this parameter is set up correctly. The drive can measure the motor rated power factor by performing a rotating autotune (see Autotune (Pr 38), below).

Pr 38 {05.012} Autotune

There are two autotune tests available in open loop mode, a stationary and a rotating test. A rotating autotune should be used whenever possible so the measured value of power factor of the motor is used by the drive.

• A stationary autotune can be used when the motor is loaded and it is not possible to remove the load from the motor shaft. The stationary test measures the Stator Resistance (05.017), Transient Inductance (05.024), Maximum Deadtime Compensation (05.059) and Current At Maximum Deadtime Compensation (05.060) which are required for good performance in vector control modes (see Control Mode later in this table). The stationary autotune does not measure the power factor of the motor so the value on the motor nameplate must be entered into Pr 09. To perform a Stationary autotune, set Pr 38 to 1, and provide the drive with both an enable signal (on terminal 11) and a run signal (on terminals 12 or 13).

• A rotating autotune should only be used if the motor is unloaded. A rotating autotune first performs a stationary autotune, as above, then a rotating test is performed in which the motor is accelerated with currently selected ramps up to a frequency of Motor Rated Frequency (Pr 39) x 2/3, and the frequency is maintained at that level for 4 seconds. Stator Inductance (05.025) is measured and this value is used in conjunction with other motor parameters to calculate Motor Rated Power Factor (Pr 09). To perform a Rotating autotune, set Pr 38 to 2, and provide the drive with both an enable signal (on terminal 11) and a run signal (on terminals 12 or 13).

Following the completion of an autotune test the drive will go into the inhibit state. The drive must be placed into a controlled disable condition before the drive can be made to run at the required reference. The drive can be put in to a controlled disable condition by removing the signal from terminal 11, setting the Drive Enable (06.015) to OFF (0) or disabling the drive via the Control Word (06.042) and Control Word Enable (06.043).

Pr 41 {05.014} Control Mode

There are several voltage modes available which fall into two categories, vector control and fixed boost.

Vector control

Vector control mode provides the motor with a linear voltage characteristic from 0 Hz to Motor Rated Frequency, and then a constant voltage above motor rated frequency. When the drive operates between motor rated frequency/50 and motor rated frequency/4, full vector based stator resistance compensation is applied. When the drive operates between motor rated frequency/4 and motor rated frequency/2 the stator resistance compensation is gradually reduced to zero as the frequency increases. For the vector modes to operate correctly the Motor Rated Power Factor (Pr 09), Stator Resistance (05.017), Maximum Deadtime Compensation (05.059) and current at Maximum Deadtime Compensation (05.060) are all required to be set up accurately. The drive can be made to measure these by performing an autotune (see Pr 38 Autotune). The drive can also be made to measure the stator resistance automatically every time the drive is enabled or the first time the drive is enabled after it is powered up, by selecting one of the vector control voltage modes.

(0) Ur S = The stator resistance is measured and the parameters for the selected motor map are over-written each time the drive is made to run. This test can only be done with a stationary motor where the flux has decayed to zero. Therefore this mode should only be used if the motor is guaranteed to be stationary each time the drive is made to run. To prevent the test from being done before the flux has decayed there is a period of 1 second after the drive has been in the ready state during which the test is not done if the drive is made to run again. In this case, previously measured values are used. Ur S mode ensures that the drive compensates for any change in motor parameters due to changes in temperature. The new value of stator resistance is not automatically saved to the drive's EEPROM.

(4) Ur I = The stator resistance is measured when the drive is first made to run after each power-up. This test can only be done with a stationary motor. Therefore this mode should only be used if the motor is guaranteed to be stationary the first time the drive is made to run after each power-up. The new value of stator resistance is not automatically saved to the drive's EEPROM.

(1) Ur = The stator resistance and voltage offset are not measured. The user can enter the motor and cabling resistance into the Stator Resistance (05.017). However this will not include resistance effects within the drive inverter. Therefore if this mode is to be used, it is best to use an autotune test initially to measure the stator resistance.

(3) Ur_Auto= The stator resistance is measured once, the first time the drive is made to run. After the test has been completed successfully the Control Mode (Pr 41) is changed to Ur mode. The Stator Resistance (05.017) parameter is written to, and along with the Control Mode (Pr 41), are saved in the drive's EEPROM. If the test fails, the voltage mode will stay set to Ur Auto and the test will be repeated next time the drive is made to run.

Fixed boost

The stator resistance is not used in the control of the motor, instead a fixed characteristic with low frequency voltage boost as defined by Pr 42, is used. Fixed boost mode should be used when the drive is controlling multiple motors. There are three settings of fixed boost available:

(2) Fixed = This mode provides the motor with a linear voltage characteristic from 0 Hz to Motor Rated Frequency (Pr 39), and then a constant voltage above rated frequency. (5) Square = This mode provides the motor with a square law voltage characteristic from 0 Hz to Motor Rated Frequency (Pr 39), and then a constant voltage above rated frequency. This mode is suitable for variable torque applications like fans and pumps where the load is proportional to the square of the speed of the motor shaft. This mode should not be used if a high starting torque is required. (6) Fixed Tapered = This mode provides the motor with a linear voltage characteristic with a tapered slip limit.

Pr 41 {05.014} Control Mode (cont)

For mode 2 and 5, at low frequencies (from 0 Hz to ½ x Pr 39) a voltage boost is applied as defined by Pr 42 as shown below:

Pr 05.027 Enable Slip Compensation

When a motor, being controlled in open loop mode, has load applied a characteristic of the motor is that the output speed droops in proportion to the load applied as shown:

In order to prevent the speed droop shown above slip compensation should be enabled. To enable slip compensation Pr 05.027 must be set to a 100 % (this is the default setting), and the motor rated speed must be entered in Pr 07 (Pr 05.008).

The motor rated speed parameter should be set to the synchronous speed of the motor minus the slip speed. This is normally displayed on the motor nameplate, i.e. for a typical 18.5 kW, 50 Hz, 4 pole motor, the motor rated speed would be approximately 1465 rpm. The synchronous speed for a 50 Hz, 4 pole motor is 1500 rpm, so therefore the slip speed would be 35 rpm. If the synchronous speed is entered in Pr 07, slip compensation will be disabled. If too small a value is entered in Pr 07, the motor will run faster than the demanded frequency. The synchronous speeds for 50 Hz motors with different numbers of poles are as follows:

2 pole = 3000 rpm, 4 pole = 1500 rpm, 6pole =1000 rpm, 8 pole = 750 rpm

8.1.2 RFC-A mode

Pr 06 {05.007} Motor Rated Current Defines the maximum motor continuous current

The motor rated current parameter must be set to the maximum continuous current of the motor. The motor rated current is used in the following:

• Current limits (see section 8.3 Current limits on page 54, for more information).

• Motor thermal overload protection (see section 8.4 Motor thermal protection on page 54, for more information)

• Vector control algorithm

Pr 08 {05.009} Motor Rated Voltage Defines the voltage applied to the motor at rated frequency

Pr 39 {05.006} Motor Rated Frequency Defines the frequency at which rated voltage is applied

The Motor Rated Voltage (Pr 08) and the Motor Rated Frequency (Pr 39) are used to define the voltage to frequency characteristic applied to the motor. The motor rated frequency is also used in conjunction with the motor rated speed to calculate the rated slip for slip compensation (see Motor Rated Speed (Pr 07), later in this table).

Pr 07 {05.008} Motor Rated Speed Defines the full load rated speed of the motor and slip

Pr 40 {05.011} Number of Motor Poles Defines the number of motor poles

The motor rated speed and motor rated frequency are used to determine the full load slip of the motor which is used by the vector control algorithm.

Incorrect setting of this parameter has the following effects:

• Reduced efficiency of motor operation

• Reduction of maximum torque available from the motor

• Reduced transient performance

• Inaccurate control of absolute torque in torque control modes

The nameplate value is normally the value for a hot motor; however, some adjustment may be required when the drive is commissioned if the nameplate value is inaccurate. A fixed value can be entered in this parameter.

When Pr 40 is set to 'Auto', the number of motor poles is automatically calculated from the Motor Rated Frequency (Pr 39), and the Motor Rated Speed (Pr 07).

Number of poles = 120 x (Motor Rated Frequency (Pr 39 / Motor Rated Speed (Pr 07) rounded to the nearest even number.

Pr 09 {05.010} Motor Rated Power Factor Defines the angle between the motor voltage and current

The power factor is the true power factor of the motor, i.e. the angle between the motor voltage and current. If the Stator Inductance (05.025) is set to zero then the power factor is used in conjunction with the Motor Rated Current (Pr 06) and other motor parameters to calculate the rated active and magnetising currents of the motor, which are used in the vector control algorithm. If the stator inductance has a non-zero value this parameter is not used by the drive, but is continuously written with a calculated value of power factor. The stator inductance can be measured by the drive by performing a rotating autotune (see Autotune (Pr 38), later in this table).

Pr 38 {05.012} Autotune

There are three autotune tests available in RFC-A mode, a stationary test, a rotating test and a mechanical load measurement test. A stationary autotune will give moderate performance whereas a rotating autotune will give improved performance as it measures the actual values of the motor parameters required by the drive. An inertia measurement test should be performed separately to a stationary or rotating autotune.

It is highly recommended that a rotating autotune is performed (Pr 38 set to 2).

• A stationary autotune can be used when the motor is loaded and it is not possible to remove the load from the motor shaft. The stationary autotune measures the Stator Resistance (05.017) and Transient Inductance (05.024) of the motor. These are used to calculate the current loop gains, and at the end of the test the values in Pr 04.013 and Pr 04.014 are updated. A stationary autotune does not measure the power factor of the motor so the value on the motor nameplate must be entered into Pr 09. To perform a Stationary autotune, set Pr 38 to 1, and provide the drive with both an enable signal (on terminal 11) and a run signal (on terminal 12 or 13).

• A rotating autotune should only be used if the motor is unloaded. A rotating autotune first performs a stationary autotune, a rotating test is then performed which the motor is accelerated with currently selected ramps up to a frequency of Motor Rated Frequency (Pr 39) x 2/3, and the frequency is maintained at the level for up to 40 s. During the rotating autotune the Stator Inductance (05.025), and the motor saturation breakpoints (Pr 05.029, Pr 05.030, Pr 05.062 and Pr 05.063) are modified by the drive. The power factor is also modified for user information only, but is not used after this point as the stator inductance is used in the vector control algorithm instead. To perform a Rotating autotune, set Pr 38 to 2, and provide the drive with both an enable signal (on terminal 11) and a run signal (on terminal 12 or 13).

• The mechanical load test can measure the total inertia of the load and the motor. A series of progressively larger torque levels are applied to the motor (20 %, 40 % … 100 % of rated torque) to accelerate the motor up to ¾ x Motor Rated Speed (Pr 07) to determine the inertia from the acceleration/deceleration time. The test attempts to reach the required speed within 5s, but if this fails, the next torque level is used. When 100 % torque is used, the test allows 60 s for the required speed to be reached, but if this is unsuccessful, a tun.1 trip is initiated. To reduce the time taken for the test, it is possible to define the level of torque to be used for the test by setting Mechanical Load Test Level (05.021) to a nonzero value. When the test level is defined, the test is only carried out at the defined test level and 60 s is allowed for the motor to reach the required speed. It should be noted that if the maximum speed allows for flux weakening then it may not be possible to achieve the required torque level to accelerate the motor fast enough. If this is the case, the maximum speed reference should be reduced.

1. The motor must be stationary at the start of the test.

2. The motor is accelerated in the required direction up to ¾ of the maximum speed reference and then decelerated to zero speed.

3. The test is repeated with progressively higher torque until the required speed is reached. To perform a mechanical load measurement autotune, set Pr 38 to 3, and provide the drive with both an enable signal (on terminal 11) and a run signal (on terminal 12 or 13). Following the completion of an autotune test the drive will go into the inhibit state. The drive

must be placed into a controlled disable condition before the drive can be made to run at the required reference. The drive can be put in to a controlled disable condition by removing the drive enable signal from terminal 11, setting the Drive Enable (06.015) to OFF (0) or disabling the drive via the control word (Pr 06.042 & Pr 06.043).

{04.013} / {04.014} Current Loop Gains

The current loop gains proportional (Kp) and integral (Ki) gains control the response of the current loop to a change in current (torque) demand. The default values give satisfactory operation with most motors. However, for optimal performance in dynamic applications it may be necessary to change the gains to improve the performance. The Current Controller Kp Gain (04.013) is the most critical value in controlling the performance. The values for the current loop gains can be calculated by performing a stationary or rotating autotune (see Autotune Pr 38 earlier in this table) the drive measures the Stator Resistance (05.017) and Transient Inductance (05.024) of the motor and calculates the current loop gains.

This will give a step response with minimum overshoot after a step change of current reference. The proportional gain can be increased by a factor of 1.5 giving a similar increase in bandwidth; however, this gives a step response with approximately 12.5 % overshoot. The equation for the integral gain gives a conservative value. In some applications where it is necessary for the reference frame used by the drive to dynamically follow the flux very closely (i.e. high speed Sensorless RFC-A induction motor applications) the integral gain may need to have a significantly higher value.

Frequency Loop Gains

(Pr 65 {03.010}, Pr 66 {03.011}

The frequency loop gains control the response of the frequency controller to a change in frequency demand. The frequency controller includes proportional (Kp) and integral (Ki) feed forward terms, and a differential (Kd) feedback term. The drive holds two sets of these gains and either set may be selected for use by the frequency controller with Pr 03.016. If Pr 03.016 = 0, gains Kp1, Ki1 and Kd1 (Pr 03.010 to Pr 03.012) are used, and if Pr 03.016 = 1, gains Kp2, Ki2 and Kd2 (Pr 03.013 to Pr 03.015) are used. Pr 03.016 may be changed when the drive is enabled or disabled.

Frequency Controller Proportional Gain (Kp), Pr 65 {03.010} and Pr 03.013

If the proportional gain has a value and the integral gain is set to zero the controller will only have a proportional term, and there must be a frequency error to produce a torque reference. Therefore as the motor load increases there will be a difference between the reference and actual frequencies. This effect, called regulation, depends on the level of the proportional gain, the higher the gain the smaller the frequency error for a given load. If the proportional gain is too high either the acoustic noise produced by numerical quantization becomes unacceptable, or the stability limit is reached.

Frequency Controller Integral Gain (Ki), Pr 66 {03.011} and Pr 03.014

The integral gain is provided to prevent frequency regulation. The error is accumulated over a period of time and used to produce the necessary torque demand without any frequency error. Increasing the integral gain reduces the time taken for the frequency to reach the correct level and increases the stiffness of the system, i.e. it reduces the positional displacement produced by applying a load torque to the motor. Unfortunately increasing the integral gain also reduces the system damping giving overshoot after a transient. For a given integral gain the damping can be improved by increasing the proportional gain. A compromise must be reached where the system response, stiffness and damping are all adequate for the application. For RFC-A Sensorless mode, it is unlikely that the integral gain can be increased much above 0.50.

Differential Gain (Kd), Pr 03.012 and Pr 03.015

The differential gain is provided in the feedback of the frequency controller to give additional damping. The differential term is implemented in a way that does not introduce excessive noise normally associated with this type of function. Increasing the differential term reduces the overshoot produced by under-damping, however, for most applications the proportional and integral gains alone are sufficient.

Gain Change Threshold, Pr 03.017

If the Frequency Controller Gain Select (03.016) = 2, gains Kp1, Ki1 and Kd1 (Pr 03.010 to Pr 03.012) are used while the modulus of the frequency demand is less than the value held by Gain Change Threshold (03.017), else gains Kp2, Ki2 and Kd2 (Pr 03.013 to Pr 03.015) will be used.

Tuning the frequency loop gains:

This involves the connecting of an oscilloscope to analog output 1 to monitor the frequency feedback. Give the drive a step change in frequency reference and monitor the response of the drive on the oscilloscope. The proportional gain (Kp) should be set up initially. The value should be increased up to the point where the frequency overshoots and then reduced slightly. The integral gain (Ki) should then be increased up to the point where the frequency becomes unstable and then reduced slightly. It may now be possible to increase the proportional gain to a higher value and the process should be repeated until the system response approaches the ideal response as shown. The diagram shows the effect of incorrect P and I gain settings as well as the ideal response.

8.2 Maximum motor rated current

Size 1 to 4:

The maximum motor rated current is the Maximum Heavy Duty Current Rating (Pr 77).

The values for the Heavy Duty rating can be found in the Power Installation Guide.

Size 5 onwards:

The maximum motor rated current allowed by the drive is greater than the Maximum Heavy Duty Current Rating (Pr 77). The ratio between the Normal Duty rating and the Maximum Heavy Duty Current Rating (Pr 77) varies between drive sizes. The values for the Normal and Heavy Duty rating can be found in the Power Installation Guide. If the Motor Rated Current (Pr 06) is set above the Maximum Heavy Duty Current Rating (Pr 77), the current limits and the motor thermal protection scheme are modified (see section 8.3 Current limits on page 54 and section

8.4 Motor thermal protection below for further information).

8.3 Current limits

The default setting for the current limit parameters is:

• 165 % x motor rated torque producing current for open loop mode.

• 175 % x motor rated torque producing current for RFC-A mode.

There are three parameters which control the current limits:

• Motoring current limit: power flowing from the drive to the motor

• Regen current limit: power flowing from the motor to the drive

• Symmetrical current limit: current limit for both motoring and regen operation

Figure 8-1 Motor thermal protection (Heavy Duty)

If Pr 04.025 is 0 the characteristic is for a motor which can operate at rated current over the whole speed range. Induction motors with this type of characteristic normally have forced cooling. If Pr 04.025 is 1 the characteristic is intended for motors where the cooling effect of motor fan reduces with reduced motor speed below 50 % of base speed/ frequency. The maximum value for K1 is 1.05, so that above the knee of the characteristics the motor can operate continuously up to 105 % current.

Figure 8-2 Motor thermal protection (Normal Duty)

The lowest of either the motoring and regen current limit, or the symmetrical current limit applies.

The maximum setting of these parameters depends on the values of motor rated current, drive rated current and the power factor.

With size 5 upwards, increasing the motor rated current (Pr 06 / Pr 05.007) above the Heavy Duty rating (default value), will automatically reduce the current limits in Pr 04.005 to Pr 04.007. If the motor rated current is then set to or below the Heavy Duty rating, the current limits will be left at their reduced values.

The drive can be oversized to permit a higher current limit setting to provide higher accelerating torque as required up to a maximum of 1000 %.

A time constant thermal model is provided to estimate the motor temperature as a percentage of its maximum allowed temperature.

The motor thermal protection is modelled using losses in the motor. The losses in the motor are calculated as a percentage value, so that under these conditions the Motor Protection Accumulator (04.019) would eventually reach 100 %.

Percentage losses = 100 % x [Load related losses]

Where:

Load related losses = [I / (K

x I

Where:

I = Current Magnitude (Pr 88)

= Motor Rated Current (Pr 06)

)]

Both settings of Pr 04.025 are intended for motors where the cooling effect of the motor fan reduces with reduced motor speed, but with different speeds below which the cooling effect is reduced. If Pr 04.025 is 0 the characteristic is intended for motors where the cooling effect reduces with motor speed below 15 % of base speed/frequency. If Pr 04.025 is 1 the characteristic is intended for motors where the cooling effect reduces with motor speed below 50 % of base speed/frequency. The maximum value for K1 is 1.01, so that above the knee of the characteristics the motor can operate continuously up to 101 % current

When the estimated temperature in Pr 04.019 reaches 100 % the drive takes some action depending on the setting of Pr 04.016. If Pr 04.016 is 0, the drive trips when Pr 04.019 reaches 100 %. If Pr 04.016 is 1, the current limit is reduced to (K - 0.05) x 100 % when Pr 04.019 reaches 100 %.

The current limit is set back to the user defined level when Pr 04.019 falls below 95 %. The thermal model temperature accumulator accumulates the temperature of the motor while the drive remains powered-up. By default, the accumulator is set to the power down value at power up. If the rated current defined by Pr 06 is altered, the accumulator is reset to zero.

The default setting of the thermal time constant (Pr 04.015) is 179 s which is equivalent to an overload of 150 % for 120 s from cold.

8.5 Switching frequency

The default switching frequency is 3 kHz, however this can be increased up to a maximum of 16 kHz by Pr 37.

If switching frequency is increased from 3 kHz the following apply:

1. Increased heat loss in the drive, which means that derating to the

output current must be applied. See the derating tables for switching frequency and ambient temperature in the Power Installation Guide.

2. Reduced heating of the motor - due to improved output waveform

quality.

3. Reduced acoustic noise generated by the motor.

4. Increased sample rate on the speed and current controllers. A trade

off must be made between motor heating, drive heating and the demands of the application with respect to the sample time required.

Lowest switching frequency in RFC-A mode is 2 kHz.

8.5.2 Maximum frequency

In all operating modes the maximum output frequency is limited to

550 Hz.

8.5.3 Over-modulation (open-loop only)

The maximum output voltage level of the drive is normally limited to an equivalent of the drive input voltage minus voltage drops within the drive (the drive will also retain a few percent of the voltage in order to maintain current control). If the motor rated voltage is set at the same level as the supply voltage, some pulse deletion will occur as the drive output voltage approaches the rated voltage level. If Pr 05.020 (Over-modulation enable) is set to 1 the modulator will allow over modulation, so that as the output frequency increases beyond the rated frequency the voltage continues to increase above the rated voltage.

This can be used for example:

• To obtain high output frequencies with a low switching frequency which would not be possible with space vector modulation limited to unity modulation depth,

• In order to maintain a higher output voltage with a low supply voltage.

The disadvantage is that the machine current will be distorted as the modulation depth increases above unity, and will contain a significant amount of low order odd harmonics of the fundamental output frequency. The additional low order harmonics cause increased losses and heating in the motor.

8.5.4 Switching frequency/Output frequency ratio

With a default switching frequency of 3 kHz, the maximum output frequency should be limited to 250 Hz. Ideally, a minimum ratio of 12:1 should be maintained between the switching frequency and the output frequency. This ensures the number of switchings per cycle is sufficient to ensure the output waveform quality is maintained at a minimum level.

8.5.1 Field weakening (constant power) operation

The drive can be used to run an induction machine above synchronous speed into the constant power region. The speed continues to increase and the available shaft torque reduces. The characteristics below show the torque and output voltage characteristics as the speed is increased above the rated value.

Figure 8-3 Torque and rated voltage against speed

Care must be taken to ensure the torque available above base speed is sufficient for the application to run satisfactorily.

The saturation breakpoint parameters (Pr 05.029, Pr 05. 030, Pr 05.062 and Pr 05.063) found during the autotune in RFC-A mode ensure the magnetizing current is reduced in the correct proportion for the specific motor. (In open loop mode the magnetizing current is not actively controlled).

8.6 CT Modbus RTU specification

This section describes the adaptation of the MODBUS RTU protocol offered on Control Techniques' products. The portable software class which implements this protocol is also defined.

MODBUS RTU is a master slave system with half-duplex message exchange. The Control Techniques (CT) implementation supports the core function codes to read and write registers. A scheme to map between MODBUS registers and CT parameters is defined. The CT implementation also defines a 32 bit extension to the standard 16 bit register data format.

8.6.1 MODBUS RTU

Physical layer

Attribute Description

Normal physical layer for multi-drop operation EIA485 2 wire

Bit stream Standard UART asynchronous symbols with Non Return to Zero (NRZ)

Each symbol consists of:-

Symbol

Baud rates 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 76800, 115200

* The drive will accept a packet with 1 or 2 stop bits but will always transmit 2 stop bits

RTU framing

The frame has the following basic format

1 start bit 8 data bits (transmitted least significant bit first) 2 stop bits*

The frame is terminated with a minimum silent period of 3.5 character times (for example, at 19200 baud the minimum silent period is 2 ms). Nodes use the terminating silence period to detect the end of frame and begin frame processing. All frames must therefore be transmitted as a continuous stream without any gaps greater or equal to the silence period. If an erroneous gap is inserted then receiving nodes may start frame processing early in which case the CRC will fail and the frame will be discarded.

MODBUS RTU is a master slave system. All master requests, except broadcast requests, will lead to a response from an individual slave. The slave will respond (i.e. start transmitting the response) within the quoted maximum slave response time (this time is quoted in the data sheet for all Control Techniques products). The minimum slave response time is also quoted but will never be less that the minimum silent period defined by 3.5 character times.

If the master request was a broadcast request then the master may transmit a new request once the maximum slave response time has expired.

The master must implement a message time out to handle transmission errors. This time out period must be set to the maximum slave response time + transmission time for the response.

8.6.2 Slave address

The first byte of the frame is the slave node address. Valid slave node addresses are 1 through 247 decimal. In the master request this byte indicates the target slave node; in the slave response this byte indicates the address of the slave sending the response.

Global addressing

Address zero addresses all slave nodes on the network. Slave nodes suppress the response messages for broadcast requests.

8.6.3 MODBUS registers

The MODBUS register address range is 16 bit (65536 registers) which at the protocol level is represented by indexes 0 through 65535.

PLC registers

Modicon PLCs typically define 4 register 'files' each containing 65536 registers. Traditionally, the registers are referenced 1 through 65536 rather than 0 through 65535. The register address is therefore decremented on the master device before passing to the protocol.

File type Description

1 Read only bits ("coil")

2 Read / write bits ("coil")

3 Read only 16bit register

4 Read / write 16bit register

The register file type code is NOT transmitted by MODBUS and all register files can be considered to map onto a single register address space. However, specific function codes are defined in MODBUS to support access to the "coil" registers.

All standard CT drive parameters are mapped to register file '4' and the coil function codes are not required.

CT parameter mapping

The Modbus register address is 16 bits in size, of which the upper two bits are used for data type selection leaving 14 bits to represent the parameter address, taking into account the slave increments the address value by 1, this results in a theoretical maximum parameter address of 163.84 (limited to 162.99 in software) when the default standard addressing mode (see Serial Mode (11.024)) is used.

To access a parameter number above 99 in any drive menu then the modified addressing mode must be used (see Serial Mode (11.024)), this will allow access to parameter numbers up to 255 but also limit the maximum menu number to 63.

The Modbus slave device increments the register address by 1 before processing the command, this effectively prevents access to parameter Pr 00.000 in the drive or option module.

The table below shows how the start register address is calculated for both addressing modes.

Parameter Addressing mode Protocol register

Decimal Hex (0x) Decimal Hex (0x)

0.01.021

Data types

The MODBUS protocol specification defines registers as 16 bit signed integers. All CT devices support this data size.

Refer to the section 8.6.7 Extended data types on page 59 for detail on accessing 32 bit register data.

8.6.4 Data consistency

All CT devices support a minimum data consistency of one parameter (16 bit or 32 bit data). Some devices support consistency for a complete multiple register transaction.

8.6.5 Data encoding

MODBUS RTU uses a 'big-endian' representation for addresses and data items (except the CRC, which is 'little-endian'). This means that when a numerical quantity larger than a single byte is transmitted, the MOST significant byte is sent first. So for example

16 - bits 0x1234 would be 0x12 0x34

Standard 120 00 78 16504 40 78

Modified 276 01 14 16660 41 14

Standard 99 00 63 16483 40 63

Modified 255 00 FF 16639 40 FF

Standard N/A N/A N/A N/A

Modified 928 03 A0 17312 43 A0

8.6.6 Function codes

The function code determines the context and format of the message data. Bit 7 of the function code is used in the slave response to indicate an exception.

The following function codes are supported:

Code Description

3 Read multiple 16 bit registers

6 Write single register

16 Write multiple 16 bit registers

23 Read and write multiple 16 bit registers

FC03 Read multiple

Read a contiguous array of registers. The slave imposes an upper limit on the number of registers, which can be read. If this is exceeded the slave will issue an exception code 2.

8.6.7 Extended data types

Standard MODBUS registers are 16bit and the standard mapping maps a single #X.Y parameter to a single MODBUS register. To support 32 bit data types (integer and float) the MODBUS multiple read and write services are used to transfer a contiguous array of 16bit registers.

Slave devices typically contain a mixed set of 16 bit and 32 bit registers. To permit the master to select the desired 16 bit or 32 bit access the top two bits of the register address are used to indicate the selected data type.

The selection is applied for the whole block access.

The 2bit type field selects the data type according to the table below:

Typ e f i e l d bits 15-14

If a 32 bit data type is selected then the slave uses two consecutive 16 bit MODBUS registers (in 'big endian'). The master must also set the correct 'number of 16 bit registers'.

Example, read Pr 20.021 through Pr 20.024 as 32 bit parameters using FC03 from node 8:

Writes when actual parameter type is different from selected

The slave will allow writing a 32 bit value to a 16 bit parameter as long as the 32 bit value is within the normal range of the 16 bit parameter.

The slave will allow a 16 bit write to a 32 bit parameter. The slave will sign extend the written value, therefore the effective range of this type of write will be -32768 to +32767.

Examples, if Pr 01.028 has a range of ±100000, and Pr 01.029 has a range of ±10000.

Reads when actual parameter type is different from selected

The slave will send the least significant word of a 32 bit parameter if that parameter is read as part of a 16 bit access.

The slave will respond with an exception response if an error is detected in the master request. If a message is corrupted and the frame is not received or the CRC fails then the slave will not issue an exception. In this case the master device will time out. If a write multiple (FC16 or FC23) request exceeds the slave maximum buffer size then the slave will discard the message. No exception will be transmitted in this case and the master will time out.

9 NV Media Card

9.1 Introduction

The Non-Volatile Media Card feature enables simple configuration of parameters, parameter back-up and drive cloning using an SD card.

The SD card can be used for:

• Parameter copying between drives

• Saving drive parameter sets

The NV Media Card (SD card) is located in the AI-Backup adaptor.

The card is not hot swappable, but the AI-Backup adaptor is “hot swapped” only when the five unit LEDs on the display are not flashing. The unit LEDs flash during the data transfer.

Figure 9-1 Installation of the SD card

1. Installing the SD card

A flat bladed screwdriver or similar tool is required in order to insert / remove the SD card fully into the AI-Backup adaptor.

Before inserting / removing the SD card into / from the AI-Backup adaptor, the AI-Backup adaptor must be removed from the drive.

The drive supports SD cards formatted with the FAT32 file system only.

9.2 SD card support

An SD memory card can be inserted in the AI-Backup Adaptor in order to transfer data to the drive, however the following limitations should be noted:

If a parameter from the source drive does not exist in the target drive then no data is transferred for that parameter.

If the data for the parameter in the target drive is out of range then the data is limited to the range of the target parameter.

If the target drive has a different rating to the source drive then the normal rules for this type of transfer apply as described later.

No checking is possible to determine if the source and target product types are the same, and so no warning is given if they are different.

If an SD card is used then the drive will recognise the following file types through the drive parameter interface.

File Type Description

It is possible for other data to be stored on the card, but this should not be stored in the <MCDF> folder and it will not be visible via the drive parameter interface.

9.2.1 Changing the drive mode

If the source drive mode is different from the target drive mode then the mode will be changed to the source drive mode before the parameters are transferred. If the required drive mode is outside the allowed range for the target then a {C.typ} trip is initiated and no data is transferred.

9.2.2 Different voltage ratings

If the voltage rating of the source and target drives is different then all parameters except those that are rating dependent (i.e. attribute RA=1) are transferred to the target drive. The rating dependent parameters are left at their default values. After the parameters have been transferred and saved to non-volatile memory a {C.rtg} trip is given as a warning. The table below gives a list of the rating dependent parameters.

9.2.3 Different option modules installed

If the option module ID code (15.001) is different for any option module installed to the source drive compared to the destination drive, then the parameters for the set-up for that option module are not transferred, but and are instead set to their default values. After the parameters have been transferred and saved to non-volatile memory, a {C.OPt} trip is given as a warning.

These files can be created on a card by the drive and then transferred to any other drive including derivatives. If the Drive Derivative (11.028) is different between the source and target drives then the data is transferred but a {C.Pr} trip is initiated.

9.2.4 Different current ratings

If any of the current rating parameters (Maximum Heavy Duty Rating (Pr 77), Maximum Rated Current (11.060) or Full Scale Current Kc (11.061)) are different between the source and target then all parameters are still written to the target drive, but some may be limited by their allowed range. To give similar performance in the target compared to the source drive the frequency and current controller gains are modified as shown below. Note that this does not apply if the file identification number is larger than 500.

9.2.5 Different variable maximums

It should be noted that if ratings of the source and target drives are different, it is possible that some parameters with variable maximums may be limited and not have the same values as in the source drive.

9.2.6 Macro files

Macro files are created in the same way as parameter files except that NV Media Card Create Special File (11.072) must be set to 1 before the file is created on the NV media card. NV Media Card Create Special File (11.072) is set to zero after the file has been created or the transfer fails. When a macro file is transferred to a drive the drive mode is not changed even if the actual mode is different to that in the file and defaults are not loaded before the parameters are copied from the file to the drive.

9.2.7 Writing to the NV Media Card

4yyy - Writes defaults differences to the NV Media Card

The data block only contains the parameter differences from the last

time default settings were loaded.

All parameters except those with the NC (Not copied) coding bit set are

transferred to the NV Media Card. In addition to these parameters all

menu 20 parameters (except Pr 20.000), can be transferred to the NV

Media Card.

Writing a parameter set to the NV Media Card (Pr 30 =

Prog (2))

Setting Pr 30 to Prog (2) and resetting the drive will save the

parameters to the NV Media Card, i.e. this is equivalent to writing 4001

to Pr 00. All NV Media Card trips apply. If the data block already

exists it is automatically overwritten. When the action is complete this

parameter is automatically reset to NonE (0).

9.2.8 Reading from the NV Media Card

6yyy - Reading from NV Media Card

When the data is transferred back to the drive, using 6yyy in Pr 00,

it is transferred to the drive RAM and the EEPROM. A parameter save is

not required to retain the data after-power down. Set up data for any

option module installed stored on the card are transferred to the drive. If

the option module installed is different between source and

destination drives, the menu for the option module slot where the

option module category is different is not updated from the card and

will contain its default values after the copying action. The drive will

produce a 'C.OPt' trip if the option module installed to the source

and the destination drives are different. If the data

is being transferred to the drive with different voltage or current rating a

'C.rtg' trip will occur.

The following drive rating dependant parameters (RA coding bit set) will

not be transferred to the destination drive by a NV Media Card when the

Reading a parameter set from the NV Media Card (Pr 30

= rEAd (1))

Setting Pr 30 to rEAd (1) and resetting the drive will transfer the

parameters from the card into the drive parameter set and the drive

EEPROM, i.e. this is equivalent to writing 6001 to Pr 00.

All NV Media Card trips apply. Once the parameters are successfully

copied this parameter is automatically reset to NonE (0). Parameters are

saved to the drive EEPROM after this action is complete.

9.2.9 Auto saving parameter changes (Pr 30 = Auto (3))

This setting causes the drive to automatically save any changes made to

menu 0 parameters on the drive to the NV Media Card. The latest menu

0 parameter set in the drive is therefore always backed up on the NV

Media Card. Changing Pr 30 to Auto (3) and resetting the drive will

immediately save the complete parameter set from the drive to the card,

i.e. all parameters except parameters with the NC coding bit set. Once

the whole parameter set is stored only the individual modified menu 0

parameter setting is updated.

Advanced parameter changes are only saved to the NV Media Card

when Pr 00 is set to 'SAVE' or a 1001 and the drive reset.

All NV Media Card trips apply. If the data block already contains information it is automatically overwritten.

If the card is removed when Pr 30 is set to 3, Pr 30 is then

automatically set to NonE (0).

When a new NV Media Card is installed Pr 30 must be set back to

Auto (3) by the user and the drive reset so the complete parameter set is

rewritten to the new NV Media Card if auto mode is still required.

When Pr 30 is set to Auto (3) and the parameters in the drive are

saved, the NV Media Card is also updated, and therefore the NV Media

Card becomes a copy of the drives stored configuration.

At power up, if Pr 30 is set to Auto (3), the drive will save the

complete parameter set to the NV Media Card. The 5 unit LEDs will flash during this operation. This is done to ensure that if a user

puts a new NV Media Card in during power down the new NV Media

Card will have the correct data.

When Pr 30 is set to Auto (3) the setting of Pr 30 itself is saved

to the drive EEPROM but not the NV Media Card.

9.2.10 Booting up from the NV Media Card on every

power up (Pr 30 = boot (4))

When Pr 30 is set to boot (4) the drive operates the same as Auto

mode except when the drive is powered-up. The parameters on the NV

Media Card will be automatically transferred to the drive at power up if

the following are true:

• A card is inserted in the drive

• Parameter data block 1 exists on the card

• The data in block 1 is type 1 to 4 (as defined in Pr 11.038)

•Pr 30 on the card set to boot (4)

The 5 unit LEDs will flash during this operation. If the drive mode is different from that on the card, the drive gives a 'C.tyP' trip and the data is not transferred.

If 'boot' mode is stored on the copying NV Media Card this makes the

copying NV Media Card the master device. This provides a very fast and

efficient way of re-programming a number of drives.

'boot' mode is saved to the card, but when the card is read, the value of

Pr 30 is not transferred to the drive.

9.2.11 Booting up from the NV Media Card on every

power up (Pr 00 = 2001)

It is possible to create a bootable parameter data block by setting

Pr 00 to 2001 and initiating a drive reset. This data block is created

in one operation and is not updated when further parameter changes are

made.

Setting Pr 00 to 2001 will overwrite the data block 1 on the card if it

already exists.

9.2.12 8yyy - Comparing the drive full parameter set

with the NV Media Card values

Setting 8yyy in Pr 00, will compare the NV Media Card file with the

data in the drive. If the compare is successful Pr 00 is simply set to 0. If the compare fails a 'C.cPr' trip is initiated.

9.2.13 7yyy - Erasing data from the NV Media

Card values

Data can be erased from the NV Media Card either one block at a time

or all blocks in one go.

• Setting 7yyy in Pr 00 will erase NV Media Card data block yyy

9.2.14 9666 / 9555 - Setting and clearing the NV

Media Card warning suppression flag

If the option module installed to the source and destination drive are

different the drive will produce a 'C.OPt' trip.

If the data is being transferred to a drive of a different voltage or current

10 Onboard PLC

10.1 Onboard PLC and Machine Control Studio

The drive has the ability to store and execute a 16 kB (less 4 kB of proxy) Onboard PLC user program without the need for additional hardware in the form of an option module.

Machine Control Studio is an IEC61131-3 development environment designed for use with Unidrive M and compatible application modules. Machine Control Studio is based on CODESYS from 3S-Smart Software Solutions.

All of the programming languages defined in the IEC standard IEC 61131-3 are supported in the Machine Control Studio development environment.

• ST (Structured text)

• LD (Ladder diagram)

• FBD (Function block diagram)

• IL (Instruction list)

• SFC (Sequential function chart)

• CFC (Continuous Function Chart). CFC is an extension to the

standard IEC programming languages

Machine Control Studio provides a complete environment for the development of user programs. Programs can be created, compiled and downloaded to a Unidrive M for execution, via the communications port on the front of the drive. The run-time operation of the compiled program on the target can also be monitored using Machine Control Studio and facilities are provided to interact with the program on the target by setting new values for target variables and parameters.

The Onboard PLC and Machine Control Studio form the first level of functionality in a range of programmable options for Unidrive M.

Machine Control Studio can be downloaded from www.controltechniques.com.

See the Machine Control Studio help file for more information regarding using Machine Control Studio, creating user programs and downloading user programs to the drive.

10.2 Benefits

The combination of the Onboard PLC and Machine Control Studio, means that the drive can replace nano and some micro PLCs in many applications

Machine Control Studio benefits from access to the standard CODESYS function and function block libraries as well as those from third parties. Functions and function blocks available as standard in Machine Control Studio include, but not limited to, the following:

• Arithmetic blocks

• Comparison blocks

•Timers

• Counters

• Multiplexers

• Latches

• Bit manipulation

Typical applications for the Onboard PLC include:

• Ancillary pumps

• Fans and control valves

• Interlocking logic

• Sequence routines

• Custom control words.

10.3 Features

The Unidrive M Onboard PLC user program has the following features:

10.3.1 Tasks

The Onboard PLC allows use of two tasks.

• Clock: A high priority real time task. The clock task interval can be set from 16 ms to 262 s in multiples of 16 ms. The parameter Onboard User Program: Clock Task Time Used (11.051) shows the percentage of the available time used by clock task. A read or write of a drive parameter by the user program takes a finite period of time. It is possible to select up to 10 parameters as fast access parameter which reduced the amount of time it takes for the user program to read from or write to a drive parameter. This is useful when using a clock task with a fast update rate as selecting a parameter for fast access reduces the amount of the clock task resource required to access parameters.

• Freewheeling: A non-real time background task. The freewheeling task is scheduled for a short period once every 256 ms. The time for which the task is scheduled will vary depending on the loading of the drive's processor. When scheduled, several scans of the user program may be performed. Some scans may execute in microseconds. However, when the main drive functions are scheduled there will be a pause in the execution of the program causing some scans to take many milliseconds. The parameter Onboard User Program: Freewheeling Tasks Per Second (11.050) shows the number of times the freewheeling task has started per second.

10.3.2 Variables

The Onboard PLC supports the use of variables with the data types of Boolean, integer (8 bit, 16 bit and 32 bit, signed and unsigned), floating point (64 bit only), strings and time.

10.3.3 Custom menu

Machine Control Studio can construct a custom drive menu to reside in menu 30 on the drive. The following properties of each parameter can be defined using Machine Control Studio:

• Parameter name

• Number of decimal places

• The units for the parameter to be display on the keypad.

• The minimum, maximum and default values

• Memory handling (i.e. power down save, user save or volatile)

• Data type. The drive provides a limited set of 1 bit, 8 bit, 16 bit and 32 bit integer parameters to create the customer menu.

Parameters in this customer menu can be accessed by the user program and will appear on the keypad.

10.3.4 Limitations

The Onboard PLC user program has the following limitations:

• The flash memory allocated to the Onboard PLC is 16 kB which includes the user program and its header which results in a maximum user program size of about 12 kB

• The Onboard PLC is provided with 2 kB of RAM.

• The drive is rated for 100 program downloads. This limitation is imposed by the flash memory used to store the program within the drive.

• There is only one real-time task with a minimum period of 16 ms.

• The freewheeling background task runs at a low priority. The drive is prioritized to perform the clock task and its major functions first, e.g. motor control, and will use any remaining processing time to execute the freewheeling task as a background activity. As the drive's processor becomes more heavily loaded, less time is spent executing the freewheeling task.

• Breakpoints, single stepping and online program changes are not possible.

• The Graphing tool is not supported.

• The variable data types REAL (32 bit floating point), LWORD (64 bit integer) and WSTRING (Unicode string), and retained variables are not supported.

11.1 Parameter ranges and Variable minimum/maximums:

Some parameters in the drive have a variable range with a variable minimum and a variable maximum value which is dependent on one of the following:

• The settings of other parameters

• The drive rating

• The drive mode

• Combination of any of the above

The tables below give the definition of variable minimum/maximum and the maximum range of these.

Range of [MAX]

Open-loop: 0.0 RFC-A: 0.0

Open-loop: 0.0 to 32000.0 RFC-A: 0.0 to 32000.0

A maximum needs to be applied to the ramp rate parameters because the units are a time for a change of speed from zero to a defined level or to maximum speed. If the change of speed is to the maximum speed then changing the maximum speed changes the actual ramp rate for a given ramp rate parameter value. The variable maximum calculation ensures that longest ramp rate (parameter at its maximum value) is not slower than the rate with the defined level, i.e. 32000.0 s/100 Hz.

The maximum frequency is taken from Maximum Speed (01.006) if Select Motor 2 Parameters (11.045) = 0, or M2

The maximum applied to these parameters is the same as other frequency reference parameters. VM_SPEED_FREQ_USER_REFS [MAX] = VM_SPEED_FREQ_REF[MAX] However the minimum is dependent on Negative Reference Clamp Enable (01.008) and Bipolar Reference Enable (01.010).

an analog output as it allows the full scale output value to be defined by the user. This maximum is subject to a limit of MOTOR1_CURRENT_LIMIT or MOTOR2_CURRENT_LIMIT depending on which motor map is currently active. The maximum value (VM_TORQUE_CURRENT_UNIPOLAR [MAX]) varies between drive sizes with default parameters loaded. For some drive sizes the default value may be reduced below the value given by the parameter range limiting.
