♦ The inverters can be installed in a side-by-side configuration, but a distance of 100

mm (3.94 inches) must be maintained if the inverters are installed on top of each other.

2.4.1 General

Warning

The inverter must always be grounded. If the inverter is not grounded correctly,

extremely dangerous conditions may arise within the inverter which could prove potentially fatal.

Operation with ungrounded (IT) supplies

The MICROMASTER will operate from ungrounded supplies and will continue to operate if an input phase is shorted to ground. If an output phase is shorted to ground, the MICROMASTER will trip and indicate F0001.

On ungrounded supplies, it will be necessary to remove the ‘Y’ capacitor from the inside of the unit and fit an output choke. The procedure for removing this capacitor is described in Appendices E and F.

Operation with Residual Current Device

If an RCD (also referred to as ELCB or RCCB) is fitted, the MICROMASTER inverters will operate without nuisance tripping, provided that:

A type B RCD is used. The trip limit of the RCD is 300mA. The neutral of the supply is grounded. Only one inverter is supplied from each RCD. The output cables are less than 50m (screened) or 100m (unscreened).

MICROMASTER 420 Operating Instructions 21 6SE6400-5AA00-0BP0

International English 2. INSTALLATION

Operation with long cables

Caution

The control, power supply and motor leads must be laid separately. Do not feed them through the same cable conduit/trunking. Never use high voltage insulation test equipment on cables connected to the inverter.

All inverters will operate at full specification with cable lengths up to 50 m screened or 100 m unscreened.

2.4.2 Power and motor connections

Warning

♦ Isolate the mains electrical supply before making or changing connections to the

unit.

♦ Ensure that the motor is configured for the correct supply voltage: single / three-

phase 230 V MICROMASTERS must not be connected to a 400 V three-phase supply.

♦ When synchronous machines are connected or when coupling several motors in

parallel, the inverter must be operated with voltage/frequency control characteristic (P1300 = 0, 2 or 3).

Caution

After connecting the power and motor cables to the proper terminals, make sure that the covers have been replaced properly before supplying power to the unit!

Note

♦ Ensure that the appropriate circuit-breakers/fuses with the specified current rating

are connected between the power supply and inverter (see table on Page 93).

♦ Use Class 1 60/75

2.4.3 Avoiding Electro-Magnetic Interference (EMI)

The inverters are designed to operate in an industrial environment where a high level of EMI can be expected. Usually, good installation practices will ensure safe and troublefree operation. If you encounter problems, follow the guidelines stated below.

Action to Take

♦ Ensure that all equipment in the cubicle is well grounded using short, thick grounding

cable connected to a common star point or busbar

♦ Make sure that any control equipment connected to the inverter (such as a PLC) is

connected to the same ground or star point as the inverter via a short thick link.

♦ Connect the return ground from the motors controlled by the inverters directly to the

ground connection (PE) on the associated inverter

♦ Flat conductors are preferred as they have lower impedance at higher frequencies ♦ Terminate the ends of the cable neatly, ensuring that unscreened wires are as short

as possible

♦ Separate the control cables from the power connections as much as possible, using

separate trunking, if necessary at 90º right angles

♦ Whenever possible, use screened leads for the connections to the control circuitry ♦ Ensure that the 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 important when the contactors are controlled from the inverter relay

♦ Use screened or armored connections for the motor connections and ground the

screen at both ends using the cable clamps

Warning

Safety regulations must not be compromised when installing inverters!

♦ MICROMASTERS operate at high voltages. ♦ When operating electrical devices, it is impossible to avoid applying hazardous

voltages to certain parts of the equipment.

♦ Emergency Stop facilities according to EN 60204 IEC 204 (VDE 0113) must remain

operative in all operating modes of the control equipment. Any disengagement of the Emergency Stop facility must not lead to uncontrolled or undefined restart.

♦ Wherever faults occurring in the control equipment can lead to substantial material

damage or even grievous bodily injury (i.e. potentially dangerous faults), additional external precautions must be taken or facilities provided to ensure or enforce safe operation, even when a fault occurs (e.g. independent limit switches, mechanical interlocks, etc.).

♦ Certain parameter settings may cause the inverter to restart automatically after an

input power failure.

♦ This equipment is capable of providing internal motor overload protection in

accordance with UL508C section 42. Refer to P0610 (level 3) and P0335. Motor overload protection can also be provided using an external PTC via a digital input.

♦ This equipment is suitable for use in a circuit capable of delivering not more than

10,000 symmetrical amperes (rms), for a maximum voltage of 230/460V when protected by a time delay fuse (see Table on Page 93).

♦ This equipment must not be used as an ‘emergency stop mechanism’ (see EN

60204, 9.2.5.4)

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 the 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 3-6.

Notes

♦ 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.

♦ In the parameter tables:

‘’ Parameters can only be changed during quick commissioning, e.g. if P0010 = 0. ‘•’ Indicates parameters that can be changed during operation.

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

‘

inverter.

All other parameters can only be changed when the inverter is stopped.

♦ Read only parameters are indicated with r instead of P.

♦ P0010 initiates “quick commissioning”.

♦ The inverter will not run unless P0010 is set to 0 after it has been accessed. This

function is automatically perform if P3900 > 0.

♦ P0004 acts as a filter, allowing access to parameters according to their functionality.

♦ If an attempt is made to change a parameter that cannot be changed in this status,

for example, cannot be changed whilst running or can only be changed in quick

commissioning, then

International English 5. SYSTEM PARAMETERS

♦ Busy Message

In some cases - when changing parameter values - the display on the BOP shows

for maximum of five seconds. This means the inverter is busy with tasks of

higher priority.

5.2.1 Access Levels

There are four levels of user access, Standard, Extended, Expert and Service selectable by parameter P0003. For most applications, Standard and Extended parameters are sufficient.

The number of parameters that appear within each functional group depends on the access level set in parameter P0003. This document describes access levels 1 and 2 (standard and extended) other settings are describe in the Reference Manual.

5.2.2 Quick commissioning (P0010=1)

It is important that parameter P0010 is used for commissioning and P0003 is used to select the number of parameters to be accessed. This parameter allows a group of parameters to be selected that will enable quick commissioning. Parameters such as Motor settings and Ramp settings are included.

At the end of the quick commissioning sequence, P3900 should be selected, which, when set to 1, will carry out the necessary motor calculations and clear all other parameters (not included in P0010=1) to the default settings. This will only happen in the Quick Commissioning mode.

5.2.3 Reset to Factory default

To reset all parameters to the factory default settings; the following parameters should be set as follows:

1. Set P0010=30.

2. Set P0970=1.

Note

The reset process takes approximately 10 seconds to complete.

The motor I

t calculation estimates the duration for which the motor can be overloaded without overheating. When the maximum allowed period has been reached the motor I calculation is 100% (see r0034). This parameter defines the calculated I which a warning (A0511) is generated.

Note:

A motor over-temperature trip (F0011) is produced at 110% of this level.

Motor overload factor (%)P0640

Defines instantaneous motor current limit as a % of the nominal motor current. This value is limited to 150% of nominal inverter current (r0207) or to 400% of the motor current (whichever is the lower).

The most recent fault events are stored in indices 0 and 1.

How to use fixed frequencies;

To use fixed frequencies it is necessary to select fixed frequency operation using P1000.

Fixed frequencies can be selected using the digital inputs, and can also be combined with an ON command.

There are three types of Fixed Frequencies.

1) Direct selection

2) Direct selection + ON command

3) Binary Coded selection + ON command

1. Direct selection (P0701 – P0703 = 15)

In this mode of operation 1 digital input selects 1 fixed frequency. If several inputs are active together, the selected frequencies are summed. E.g. (FF1 + FF2 + FF3).

Note:

An ON command is also required to start the inverter e.g. from keypad or serial link etc.

2. Direct selection + ON command (P0701 – P0703 = 16)

P1200 Start on the fly

Starts inverter onto a spinning motor.

If it is possible that the motor is still spinning e.g. after a short mains break, or if the motor can be driven by the load then flying restart must be used – otherwise overcurrent trips will occur.

This function is particularly useful for motors with high inertia loads.

Possible Settings:

0 “flying restart inactive” 1 “flying restart always active”, starts in setpoint direction 2 “flying restart on power up, fault, OFF2”, starts in setpoint direction 3 “flying restart on fault, Off2”, starts in setpoint direction 4 “Flying restart always active.

Warning: Setting 2 to 5 can cause the motor to restart unexpectedly!

Note

Auto restart will only work if the ON command remains constantly present. E.g. via a digital input wire link.

If the motor could still be turning or is possibly still being driven by the load, flying restart must also be enabled (P1200).

Duration of DC braking after OFF1P1233

Defines duration for which DC injection braking is to be active following an OFF1 command.

Possible settings:

0 = not active following OFF1 1 – 250 = active for the specified duration

Note

The DC braking function causes the motor to stop rapidly by applying a DC braking current (the current applied also holds the shaft stationary). When the DC braking signal is applied, the inverter output pulses are blocked and the DC current is only applied once the motor has been sufficiently demagnetized. (Demagnetization time is automatically calculated from Motor data).

Warning

Frequent use of long periods of DC braking can cause the motor to overheat.

Compound braking currentP1236

Defines DC level superimposed on AC waveform. This form of braking becomes active following an OFF1 / OFF3 command.

Increasing the value will generally improve braking performance; however, if you set the value too high, an overvoltage trip may result.

PI mode Allows the User to Enable/Disable the PI controller

Possible settings:

Note 1

The PI closed loop controller can be enabled by the setting 1 with this function.

Once the PI controller is enabled, the normal ramp times set in P1120 and P1121 are

automatically disabled, as are the normal frequency setpoints. However, following an OFF1 or OFF 3 command the inverter output frequency will be ramped to zero using the ramp time set in P1121 (P1135 for OFF3).

Note 2

The PI setpoint source is selected using P2253. The PI setpoint and PI feedback signal are interpreted as % values (not Hz). The output of the PI controller is displayed as a percentage and then normalized into Hz through P2000 when PI is enabled.

Note 3

The minimum and maximum motor frequencies (P1080 and P1082) as well as the skip

frequencies (P1091 to P1094) are still active on the inverter output. However enabling skip frequencies with P1 control can lead to instabilities.

In user access level 2 you will need to set P2200 to enable the setpoint source. In addition you can set any of the digital input parameters to fixed PI setpoint via the digital inputs (P0701 – P0703.)

There are three modes of selection for the PI fixed setpoint.

1 Direct selection (P0701 = 15 or P0702 = 15, etc)

In this mode of operation 1 digital input selects 1 fixed PI fixed setpoint.

If several inputs are programmed to PI fixed setpoint and selected together, the selected setpoints are summed.

To start the motor (enable pulses), an ON command is needed either from the keypad or from the digital inputs or USS in this mode.

2 Direct selection with ON Command (P0701 = 16 or P0702 = 16, etc)

Description as for 1), except that this type of selection issues an ON command coincident with any setpoint selection.

You may mix different types of fixed frequencies; remember, however, they will be summed if selected together.

P2271 PI transducer type

Allows the User to select the PI feedback signal Transducer type.

0: = [default] if the feedback signal is less than the PI setpoint the PI controller will

increase motor speed to correct this

1: = if the feedback signal is less than the PI setpoint the PI controller will reduce motor

speed to correct this

Note

It is very important that the transducer type is correctly selected. If you are unsure that it should be either 0 or 1 you can determine the actual type as follows:

Disable the PI function (P2200 = 0). Increase the motor frequency while measuring the feedback signal. If the feedback signal increases with an increase in motor frequency the transducer type should be 0.

If the signal decreases with an increase in motor frequency the transducer type should be set to 1.

PI proportional gainP2280

Allows the User to set the proportional gain of the PI controller.

The PI controller on MM420 is implemented using the standard model:

error

output

Best results are usually obtained if both P and I terms are enabled. If the system is liable to sudden step changes in feedback signal, the P term should usually be set to a small value (L 0.5) with a faster I term for optimum performance.

If the P term is set to 0 the I term acts on the square of the error signal.

PI integral timeP2285

Allows the User to set the PI controller integral time constant.

6.2 Troubleshooting with the Basic Operator Panel

If the display shows a fault or warning code, please refer to Section 6.3 and the following MM420 Fault Codes.

If the motor fails to start when the ON command has been given:

• Check that P0010 = 0.

• Check that a valid ON signal is present.

• Check that P0700 = 2 (for digital input control) or

P0700 = 1 (for BOP control).

• Check that the setpoint is present (0 to 10V on Terminal 3) or the setpoint has been entered into the correct parameter, depending upon the setpoint source (P1000). See Section 5.3 on page 66.

If the motor fails to run after changing the parameters, set P0010 = 30 then P0970 = 1 and press P to reset the inverter to the factory default parameter values.

Now use a switch between terminals 5 and 8 on the control board. The drive should now run to the defined setpoint by analogue input.
