2.1 Wiring Guidelines to Minimi se the Effects of EMI

The inverters are designed to operate in an industrial environment where a high level of Electro-Magnetic Interference (EMI) can be expected. Usually, good installation practices will ensure safe and trouble-free operation. However, if problems are encountered, the following guidelines may prove useful. In particular, grounding of the system 0V at the inverter, as described below, may prove effective. Figure 1 illustrates how an RFI suppression filter should be installed.

(1) Ensure that all equipment in the cubicle is well earthed using short, thick earthing cable connected to

a common star point or busbar. It is particularly important that any control equipment that is connected to the inverter (such as a PLC) is connected to the same earth or star point as the inverter via a short, thick link. Flat conductors (e.g. braids or metal brackets) are preferred as they have lower impedance at high frequencies.

The return earth from motors controlled by the inverters should be connected directly to the earth connection (PE) on the associated inverter.

(2) Wherever possible, use screened leads for connections to the control circuitry. Terminate the ends of

the cable neatly, ensuring that unscreened wires are as short as possible. Use cable glands whenever possible.

(3) Separate the control cables from the power connections as much as possible, using separate

trunking, etc. If control and power cables cross, arrange the cables so that they cross at 90° if possible.

(4) Ensure that contactors in the cubicle are suppressed, either with R-C suppressors for AC contactors

or ‘flywheel’ diodes for DC contactors, fitted to the coils. Varistor suppressors are also effective. This is particularly important if the contactors are controlled from the relay on the inverter.

(5) Use screened or armoured cables for the motor connections and ground the screen at both ends via

the cable glands.

(6) If the drive is to be operated in an Electro-magnetic noise-sensitive environment, the RFI footprint

filter kit should be used to reduce the conducted and radiated interference from the inverter. For optimum performance, there should be a good conductive bond between filter and metal mounting plate.

On no account must safety regulations be compromised when installing inverters!

2.3.5 Motor Overload Protection

When operated below rated speed, the cooling effect of fans fitted to the motor shaft is reduced. Consequentially, most motors require de-rating for continuous operation at low frequencies. To ensure that motors are protected against overheating under these conditions, a PTC temperature sensor must be fitted to the motor and connected to the inverter control terminals as shown in Figure 7.

Note: To enable the trip function, set parameter P051, P052 or P053 =19.

3.2 Basic Operation

Refer to section 5 for a full description of each parameter.

3.2.1 General

(1) The inverter does not have a main power switch and is live when the mains supply is connected. It waits,

with the output disabled, until the RUN button is pressed or for the presence of a digital ON signal at terminal 5 (rotate right) or terminal 6 (rotate left) -

see parameters P051 - P053

(2) If output frequency is selected to be displayed (P001 = 0), the corresponding setpoint is displayed

approximately every 1.5 seconds while the inverter is stopped.

(3) The inverter is programmed at the factory for standard applications on Siemens four-pole standard

motors. When using other motors it is necessary to enter the specifications from the motor’s rating plate into parameters P081 to P085

(see Figure 10)

. Note: Access to these parameters is not possible

unless P009 has been set to 002 or 003.

3.2.3 Basic Operation - 10 Step Guide

The basic method of setting up the inverter for use is described below. This method uses a digital frequency setpoint and requires only the minimum number of parameters to be changed from their default settings. It assumes that a standard Siemens four-pole motor is connected to the inverter

(see section 3.2.1 if a different

motor type is being used)

Step /Action Button Display

1. Apply mains power to the inverter. The display will alternate between the actual frequency (0.0 Hz) and the

requested frequency setpoint (5.0 Hz default).

2. Press the parameterisation button.

3. Press the ∆ button until parameter P005 is displayed.

4. Press P to display the current frequency setpoint (5 Hz is the factory default setting).

5. Press the ∆ button to set the desired frequency setpoint (e.g. 35 Hz).

6. Press P to lock the setting into memory.

7, Press the ∇ button to return to P000.

8. Press P to exit the parameterisation procedure. The display will alternate between the current frequency and the requested

frequency setpoint.

9. Start the inverter by pressing the RUN button. The motor shaft will start to turn and the display will show that the inverter

is ramping up to the setpoint of 35 Hz.

Note

The setpoint will be achieved after 7 seconds (35 Hz/50 Hz x 10 s *).

If required, the motor’s speed (i.e. frequency) can be varied directly by using the ∆ ∇ buttons. (Set P011 to 001 to enable the new frequency setting to be retained in memory during periods when the inverter is not running.)

10. Switch the inverter off by pressing the STOP button. The motor will slow down and come to a controlled stop (takes 7 s **).

* Default ramp-up time is 10 s to reach 50 Hz (defined by P002 and P013). ** Default ramp-down time is 10 s from 50 Hz (defined by P003 and P013).

4. OPERATING MODES English

6/09/9

4. OPERATING MODES

4.1 Digital Control

For a basic startup configuration using digital control, proceed as follows: (1) Connect control terminal 5 to terminal 8 via a simple on/off switch. This sets up the motor for clockwise

rotation (default). (2) Apply mains power to the inverter. Set parameter P009 to 002 or 003 to enable all parameters to be

adjusted. (3) Check that parameter P006 is set to 000 to specify digital setpoint. (4) Set parameter P007 to 000 to specify digital input (i.e. DIN1 (terminal 5) in this case) and disable the front

panel controls. (5) Set parameter P005 to the desired frequency setpoint. (6) Set parameters P081 to P085 in accordance with the rating plate on the motor

(see Figure 10)

Note: In many cases, when default factory parameters are used, the default stator resistance set in

P089 will generally suit the default power rating set in P085. Should the inverter and motor ratings differ greatly, it is recommended that the stator resistance of the motor is measured and entered manually into P089. Continuous Boost (P078) and Starting Boost (P079) are dependent on the value of Stator Resistance - too high a value may cause overcurrent trips

(7) Set the external on/off switch to ON. The inverter will now drive the motor at the frequency set by P005.

4.2 Analogue Control

For a basic startup configuration using analogue voltage control, proceed as follows: (1) Connect control terminal 5 to terminal 8 via a simple on/off switch. This sets up the motor for clockwise

rotation (default). (2) Connect a 4.7 kΩ potentiometer to the control terminals as shown in Figure 6 or connect pin 2 (0V) to pin

4 and a 0 - 10 V signal between pin 2 (0V) and pin 3 (AIN+). (3) Apply mains power to the inverter. Set parameter P009 to 002 or 003 to enable all parameters to be

adjusted. (4) Set parameter P006 to 001 to specify analogue setpoint. (5) Set parameter P007 to 000 to specify digital input (i.e. DIN1 (terminal 5) in this case) and disable the front

panel controls. (6) Set parameters P021 and P022 to specify the minimum and maximum output frequency settings. (7) Set parameters P081 to P085 in accordance with the rating plate on the motor

(see Figure 10).

4.3 Stopping the Motor

Stopping can be achieved in several ways:

• Cancelling the ON command or pressing the OFF button (O) on the front panel causes the inverter to

ramp down at the selected ramp down rate

(see P003)

• OFF2 - operation causes the motor to coast to a standstill

(see parameters P051 to P053)

• OFF3 - operation causes rapid braking

(see parameters P051 to P053)

• DC injection braking up to 250% causes a rapid stop

(see P073)

4.4 If the Motor Does Not Start Up

If the display shows a fault code, refer to Section 6. If the motor does not start up when the ON command has been given, check that the ON command is valid,

check if a frequency setpoint has been entered in P005 and check that the motor specifications have been entered correctly under parameters P081 to P085.

If the inverter is configured for operation via the front panel (P007 = 001) and the motor does not start when the RUN button is pressed, check that P121 = 001 (RUN button enabled).

If the motor does not run after parameters have been changed accidentally, reset the inverter to the factory default parameter values by setting parameter P944 to 001 and then pressing P.

4.5 Local and Remote Control

The inverter can be controlled either locally (default), or remotely via a USS data line connected to the RS485 D-type connector on the front panel. (Refer to parameter P910 in section 5 for the available remote control options.)

When local control is used, the inverter can only be controlled via the front panel or the control terminals. Control commands, setpoints or parameter changes received via the RS485 interface have no effect.

When operating via remote control the inverter will not accept control commands from the terminals.

Exception: OFF2 or OFF3 can be activated via parameters P051 to P053 (refer to parameters P051 to P053 in section 5).

Several inverters can be connected to an external control unit at the same time. The inverters can be addressed individually.

4.6 Closed Loop Control

4.6.1 General Description

The MICROMASTER provides a PI control function for closed loop control

(see Figure 11)

. PI control is ideal for temperature or pressure control, or other applications where the controlled variable changes slowly or where transient errors are not critical. This control loop is not suitable for use in systems where fast response times are required.

Note: The closed loop function is not designed for speed control, but can be used for this provided that fast

response times are not required.

When closed loop PI control is enabled (P201 = 002), all setpoints are calibrated between zero and 100%, i.e. a setpoint of 50.0 = 50%. This allows general purpose control of any process variable that is actuated by motor speed and for which a suitable transducer is available.

4.6.2 Hardware Setup

Connect the outputs from the external feedback transducer to control terminals 3 and 4. This analogue input accepts a 0/2 - 10 V signal, has 10-bit resolution and permits a differential (floating) voltage. Ensure that the values of parameters P023 and P024 are set to 000 and that P006 is set to 000 or 002.

15 V dc power for the feedback transducer can be supplied from terminals 8 and 9 on the control block.

4.6.3 Parameter Settings

Closed loop control cannot be used unless P201 is first set to 002. Most of the parameters associated with closed loop control are shown in Figure 11. Other parameters which are also associated with closed loop control are as follows:

P001 (value = 007) P061 (value = 012 or 013) P210 P220

Descriptions of all closed loop control parameters are provided in section 5. For further detailed information about PI operation refer to the Siemens DA 64 Catalogue.

5. SYSTEM PARAMETERS

Parameters can be changed and set using the membrane-type buttons to adjust the desired properties of the inverter, such as ramp times, minimum and maximum frequencies etc. The parameter numbers selected and the setting of the parameter values are indicated in the four digit LED display.

Note: If you press the ∆ or ∇ button momentarily, the values change step by step. If you keep the buttons

pressed for a longer time, the values scroll through rapidly.

Access to parameters is determined by the value set in P009. Check that the key parameters necessary for your application have been programmed.

Note: In the following parameter table:

‘•’ Indicates parameters that can be changed during operation. ‘



’ Indicates that the value of this factory setting depends on the rating of the inverter.

To increase the resolution to 0.01 when changing frequency parameters, instead of pressing P momentarily to return to the parameter display, keep the button pressed until the display changes to ‘- -.n0’ (n = the current tenths value, e.g. if the parameter value = ‘055.8’ then n = 8). Press ∆ or ∇ to change the value (all values between .00 and .99 are valid) and then press P twice to return to the parameter display.

If parameters are changed accidentally, all parameters can be reset to their default values by setting parameter P944 to 1 and then pressing P.

Setting this parameter to ‘1’ enables the inverter t o restart automatically after a mains break or ‘brownout’, provided the run/stop switch is still closed, P007 = 0 and P910 = 0, 2 or 4.

0 = Disabled 1 = Automatic restart

P016 •

Start on the fly 0 - 2

[0]

Allows the inverter to start onto a spinning motor. Under normal circumstances the inverter runs t he mot or up from 0 Hz.

However, if the motor is still spinning or is being driven by the load, it will undergo braking before running back up to the setpoint - t his can cause an overcurrent trip. By using a f lying restart , t he invert er ‘hom es in’ on t he motor's speed and runs it up from that speed to the set point . Note: If the motor has stopped or is rotati ng slowly, some ‘rocking’ m ay occur as the inverter senses the direction of rot ati on prior t o restart ing. (See also P020)

0 = Normal restart 1 = Flying restart after power up, fault or OFF2 ( if P 018 = 1). 2 = Flying restart every time (useful in circumstances where the

motor can be driven by the load).

P017 •

Smoothing type 1 - 2

Automatic restart after fault:

0 = Disabled 1 = The inverter will attempt to restart up to 5 times after a fault. If

the fault is not cleared after the 5th attempt, the invert er will remain in the fault state until reset.

WARNING: While waiting to re-start, the display will flash. This

means that a start is pending and may happen at any time. Fault codes can be observed in P930.

WARNING: The motor can automatically run without a

potentiometer or voltage source connected between pins 3 and 4.

WARNING: With P023=2, the inverter will automatically start

when V goes above 1 V. This equally applies to analogue and digital control (i.e. P006 = 0 or 1).

2 = Scaling of digital/fixed setpoint by analogue input (P023) in

the range 0 - 100%.

Note: By selecting a combination of reversed negative fixed

frequency settings and analogue setpoint addition, it is possible to configure the inverter for ‘centre zero’ operation with a +/-5 V supply or a 0 - 10 V potentiometer so t hat the output frequency can be 0 Hz at any position, including the centre position.

P064

External brake stopping time (seconds)

0 - 20.0

[1.0]

As P063, only effective if the relay output is set to control an ext ernal brake. This defines the period for which the inverter continues to run at the minimum frequency after ramping down and while the ext ernal brake is applied.

Notes: (1) Settings for P063 and P064 should be slightly longer

than the actual time taken for t he ext ernal brake t o apply and release respectively.

P073 •

DC injection braking (%) 0 - 250

[0]

This stops the motor by applying a DC current. This causes heat to be generated in the motor rather than t he invert er and holds the shaf t stationary until the end of the braking period. Braking is effective for t he period of time set by P003.

The DC brake can be activated using DIN1 - DIN3 (braking is active for as long as the DIN is high - see P051 - P053).

WARNING: Frequent use of long periods of dc injection braking

can cause the motor to overheat. If DC injection braking is enabled via a digital input

then DC current is applied for as long as the digital input is high. This causes heat in the motor.

P074 •

I2t motor derating 0 - 1

The time taken to trip is dependent on t he diff erence between t he overload current and the nominal mot or current rat ing st ored in P 083 typically a 150% overload will result in a switch-off in 1 - 2 minutes.

WARNING: Where motor thermal pro tection is r equi red , an external

P076 •

Pulse frequency 0 - 7

[0 or 4]

Sets the pulse frequency (from 2 to 16 kHz) and the PWM mode. If silent operation is not absolutely necessary, the losses in the inverter as well as the RFI emissions can be reduced by selecting lower pulse frequencies.

Note: When P076 = 0/1, the display of the current at frequencies

below 10 Hz is less accurate.

400V inverters require the continuous current rating reduced for operation below 5Hz, when operating at switching frequencies greater than 4kHz and with boost values greater than 100% (P078 + P079). These are typically as follows:

Controls the relationship between the speed of the motor and the voltage supplied by the inverter. One of two modes can be selected:

0/1 = Linear voltage/f requency

Use this curve for synchronous motors or motors connected in parallel.

2 = Quadratic voltage/frequency relationship

This is suitable for centrifugal pumps and fans.

P078 •

Continuous boost (%) 0 - 250

[100]

Operates continuously over the whole frequency range. For many applications it is necessary to increase low frequency torque.

This parameter sets the start-up voltage at 0 Hz to adjust the available torque for low frequency operation. 100% setting will produce rated motor current at low frequencies.

WARNING: If P078 is set too high, o verh eating of the motor

and/or an overcurrent trip (F002) can occur.

P079 •

Starting boost (%) 0 - 250

[0]

For drives which require a high initial starting torque, it is possible to set an additional current (added to the setting in P078) during ramping. This is only effective during initial start up and until the frequency setpoint is reached.

Note: This increase is in addition to P078.

6. FAULT CODES

In the event of a failure, the inverter switches off and a fault code appears on the display. The last fault that

occurred is stored in parameter P930. e.g. ‘0003’ indicates that the last error was F003.

Fault Code Cause Corrective Action

F001

Overvoltage Check whether supply voltage is within the limits indicated on the rating plate.

Increase the ramp down time (P003). Check whether the required braking power is within the specified limits.

F002

Overcurrent Check whether the motor power corresponds to the inverter power.

Check that the cable length limits have not been exceeded. Check motor lead and motor for short-circuits and earth faults. Check whether the motor parameters (P081 - P 086) correspond with the motor being used. Check the stator resistance (P089). Increase the ramp-up time (P002). Reduce the boost set in P078 and P079. Check whether the motor is obstructed or overloaded.

F003

Overload Check whether the motor is overloaded.

Increase the maximum motor frequency if a motor with high slip is used.

F005

Inverter overtemperature (internal PTC)

Check that the ambient temperature is not t oo high. Check that the air inlet and outlet are not obstruct ed. Check that the integral fan is working.

F008

USS protocol timeout Check the serial interface.

Check the settings of the bus master and P091 - P093. Check whether the timeout interval is too short (P093).

F010

Initialisation fault / Param eter loss * Check the entire parameter set. Set P009 to ‘0000’ before power down.

F011

Internal interface fault * Switch off power and switch on again.

F012

External trip (PTC) Check if motor is overloaded.

F013

Programme fault * Switch off power and switch on again.

F018

Auto-restart after fault. Automatic re-start af ter fault (P018) is pending.

WARNING: The inverter may start at any time.

F030

PROFIBUS link failure Check the integrity of the link.

F031

Option module to link failure Check the integrity of the link.

F033

PROFIBUS configuration error Check the PROFIBUS configuration.

F036

PROFIBUS module watchdog trip Replace PROFIBUS module

F074

Motor overtemperature by I2t calculation

Check that the motor current does not exceed the value set in P083.

F106

Parameter fault P006 Parameterise fixed frequency(ies) and/or motor potentiom et er on the digital

inputs.

F112

Parameter fault P012/P013 Set param eter P012 < P013.

F151 - F153

Digital input parameter fault Check the settings of digital inputs P051 to P053.

F188

Automatic calibration failure Motor not connected to inverter - connect motor.

If the fault persists, set P088 = 0 and then enter the stator resistance of t he motor into P089 manually.

F201

P006 = 1 while P201 = 2 Change paramet er P 006 and/or P201.

F212

Parameter fault P211/P212 Set param eter P211 < P212.

Ensure that the wiring guidelines described in section 2.1 have been complied with.

When the fault has been corrected the inverter can be reset. To do this press button P twice (once to display P000 and the second time to reset the fault ), or erase t he fault via a binary input (see parameters P051 - P053 in section 5) or via the serial interface.

8.1 Application Example

Setup procedure for a simple application

Motor: 220 V

1.5 kW output power

Application requirements: Setpoint adjustable via potentiometer 0 - 50 Hz

Ramp up from 0 to 50 Hz in 15 seconds

Ramp down from 50 to 0 Hz in 20 seconds Inverter used: MM150 (6SE9216-8BB40) Settings: P009 = 2 (all parameters can be altered)

P081 - P085 = values given on motor rating plate

P006 = 1 (analogue input)

P002 = 15 (ramp up time)

P003 = 20 (ramp down time) This application is now to be modified as follows:

Operation of motor up to 75 Hz (voltage/frequency curve is linear up to 50 Hz). Motor potentiometer setpoint in addition to analogue setpoint . Use of analogue setpoint at maximum 10 Hz. Ramp times to remain the same.

Parameter adjustments: P009 = 2 (all parameters can be altered)

P013 = 75 (maximum motor frequency in Hz)

P006 = 2 (setpoint via motor potentiometer or fixed setpoint)

P024 = 1 (analogue setpoint is added)

P022 = 10 (maximum analogue setpoint at 10 V = 10 Hz)

8.2 USS Status Codes

The following list gives the meaning of status codes displayed on the front panel of the inverter when the serial link is in use and parameter P001 is set to 006:

001 Message OK 002 Slave address received 100 Invalid start character 101 Timeout 102 Checksum error 103 Incorrect message length 104 Parity fail

Notes

(1) The display flashes whenever a byte is received, thus giving a basic indication that a serial link

connection is established.

(2) If ‘100’ flashes on the display continuously, this usually indicates a bus termination fault.

8.3 Electro-Magnetic Compatibility (EMC)

All manufacturers / assemblers of electrical apparatus which performs a complete intrinsic function which is placed on the market as a single unit intended for the end user must comply with the EMC directive EEC/89/336 after January 1996. There are three routes by which the manufacturer/assembler can demonstrate compliance:

Self-Certification

This is a manufacturer’s declaration that the European standards applicable to the electrical environment for which the apparatus is intended have been met. Only standards which have been officially published in the Official Journal of the European Community can be cited in the manufacturer’s declaration.

Technical Construction File

A technical construction file can be prepared for the apparatus describing its EMC characteristics.

This file must be approved by a ‘Competent Body’ appointed by the appropriate European government organisation. This approach allows the use of standards which are still in preparation.

EC Type-Examination Certificate

This approach is only applicable to radio communication transmitting apparatus.

The MICROMASTER units do not have an intrinsic function until connected with other components (e.g. a motor). Therefore, the basic units are not allowed to be CE marked for compliance with the EMC directive. However, full details are provided below of the EMC performance characteristics of the products when they are installed in accordance with the wiring recommendations in section 2.1.

Three classes of EMC performance are available as detailed below. Note that these l evels of performance are only achieved when using the default switching frequency (or less) and a maximum motor cabl e length of 25 m.

Class 1: General Industrial

Compliance with the EMC Product Standard for Power Drive Systems EN 68100-3 for use in Second Environment (Industrial) and Restricted Distribution.

EMC Phenomenon Standard Level

Emissions:

Class 3: Filtered - for residential, commercial and light industry

This level of performance will allow the manufacturer / assembler to self-certify compliance of their apparatus with the EMC directive for the residential, commercial and light industrial environment as regards the EMC performance characteristics of the power drive system. Performance limits are as specified in the generic emission and immunity standards EN 50081-1 and EN 50082-1.

8.4 Environmental Aspects

Transport and Storage

Protect the inverter against physical shocks and vibration during transport and storage. The unit must also be protected against water (rainfall) and excessive temperatures

(see section 7).

The inverter’s packaging is re-usable. Retain the packaging or return it to the manufacturer for future use. If the unit has been in storage (non-operational) for more than one year, you must re-form the DC-link

capacitors before use. Refer to your local Siemens sales office for advice on the procedure.

Dismantling and Disposal

The unit can be broken-down to its component parts by means of easily-released screw and snap connectors.

The component parts can be re-cycled, disposed of in accordance with local requirements or returned to the manufacturer.
