This chapter describes the softstarter in general, specifications as well as available accessories and spare parts.

3.1

The PSTX softstarter is designed with the latest technology for soft start and soft stop of squirrel cage motors. The softstarter has several advanced motor protection features as standard.

Bypass

Softstarter range PSTX30...370 have integrated by-pass components. For PSTX210...370, this is a three phase by-pass contactor. In an emergency case, it is possible to start the motor DOL with this contactor.

User interface

The keypad on the front is designed with Navigation keys,

Selection softkeys, Start and Stop keys, Local or Remote key, Information key and a clear information display. It is possible to choose between 15 different user languages.

The softstarter can be controlled in three different ways:

• Hardwire inputs control

• Keypad control (either attached to the softstarter front or detached and connected with the cable included)

• Fieldbus communication interface (by built in Modbus,

Anybus module or the FieldBusPlug with adapter)

Only one type of control method can be enabled simultaneously. Default selection is hardware input s control.

Fans

The integrated fans for cooling are running only during ramping (start/stop) and when the heat sink temperature is above a certain level. The temperature is monitored by a thermistor.

With the keypad, settings can be set as individual parameter settings or as a selection of predefined parameters for different applications.

Most parameters have one possible setting, but some parameters have extra settings for sequence start. The default parameter settings are stored in the unit so that a reset to default can be done at any time.

When the fieldbus communication is selected, most parameters can also be modified from this interface.

Programmable inputs (Sequence start)

36

The softstarter can start and stop up to three individual motors used in different applications with different parameter sets. The parameter set is chosen via input signals to the softstarter.

If the softstarter trips for any reason, and the trip is supposed to stop the motor, all motors will be stopped.

When sequence start is going to be used, the wiring should be according to

Figure 36 or Figure 37.

The start command (terminal 13, 14, 16 and 17) must be maintained during operation, otherwise a direct stop will be performed.

Soft stop can only be performed for the motor currently fed by the softstarter, and will be achieved by giving a stop command (terminal 4).

5.1.2.8

PTC/PT100 input

If the motor is equipped with PTC or PT100 elements, the cables shall be connected to terminals 23 and 24.

See chapter 7 Function settings for programming.

The PTC input uses the same terminals as the

Analogue output and only one of these functions can be used at the same time.

3-wire measurement for PT100

To minimize the influence of the wire resistance, a three-wire connection is usually used. By means of the additional wire, two measuring circuits are created. One of these two circuits is used for reference. This way, the tripping device can calculate and take into account the wire resistance automatically.

See Figure 41.

2-wire measurement for PT100

When using 2-wire temperature sensors, the sensor resistance and the wire resistance are added together.

The resulting systematic errors must be taken into account when adjusting the tripping device. A jumper must be connected between the terminals T2 and T3.

Table 1 Line length in meter can be used for PT100 sensors to determine the temperature errors caused by the line length.

Analogue output

The softstarter has one output for a configurable analog output signal (terminals 29 and 30). The load resistance is maximum 500 ohm for current output, and minimum 500 ohm for voltage output.

The output signal ranges available are 0-10 V, 0 – 20mA or 4-20mA. The default setting is 4-20mA.

The analogue output has its own terminal for the positive output, it is not shared with any other function on the softstarter and it shall refer to the functional ground.

The analogue output can be selected to show:

I (A), U (V), P (kW), P (Hp), Q (kVAr), S (kVA), cos Phi, Motor temp, SCR temp and Energy (kWh).

If the analogue output is used, the cables shall be connected to terminals 29 and 30.

See Figure 43.

Softstarter states

The softstarter has several operational states, in which different functions are available.

Functions can be operational in one or more softstarter states. If a function is not operational in all states, this is noted in the respective function description.

The softstarter has the following states:

• Individual function

• Pre-start

• Stand by

• Start ramp

• Stop ramp

• TOR (Top of ramp)

Pre-start

In Pre-start state the softstarter runs functions that are intended to run before the softstarter goes into Start ramp state. A pre start function runs during a configurable pre set time. Then the softstarter continues to Start ramp state:

Pre-start functions are:

• Motor heating

• Stand still brake

• Slow speed forward

• Slow speed reverse

The pre-start functions can also be run as individual functions.

Top of ramp

When the motor reaches Top of ramp, (100 % nominal speed) the softstarter closes the by-pass and do not control the motor. In Top of ramp state the softstarter only runs diagnostics.

Stand by

In Stand by state the softstarter runs no functions except diagnostics.

Individual function

In Individual function state, the softstarter runs individual functions.

Individual functions are:

• Motor heating

• Stand still brake

• Slow speed forward

• Slow speed reverse

7

Start ramp

In Start ramp state the softstarter runs different settable start functions to soft start a motor by controlling the output voltage or torque.

The Start ramp ends and goes into Top of ramp state when the output voltage reaches

100 % voltage.

Settable start functions are:

• Voltage start ramp

• Tourqe start ramp

• Full voltage start ramp

Stop ramp

In Stop ramp state the softstarter runs stop functions to soft stop a motor by controlling the output voltage or torque.

The stop ramp state ends and goes into stand by state when the output voltage reaches the pre-set Stop ramp end level.

Settable stop functions are:

• Voltage stop ramp

• Tourqe stop ramp

• No ramp

Motor Current Ie

Set the motor current before the softstarter is used for the first time.

The setting of this parameter shall be configured to the rated nominell current of the motor.

WARNING

All PSTX softstarters must be configured to the rated current of the motor.

Motor Current Ie is configured with the following parameters:

Parameter

01.01 Motor Current Ie

Description

Set the nominal current of the motor. For good performance it is important that it is set to the correct value. For Inside Delta connection, this parameter shall be set to 58% of the nominal motor current.

Setting range Default value

9.0 A...1250A

*9.0 A

* Depends on softstarter model.

7.1 Voltage ramp

When using the Voltage ramp, the voltage increases linearly from Initial start level to full voltage during start, and decreases linearly from the Step down level to Stop end voltage level during stop,

see Figure 77.

Since the torque depends on both the voltage and the current, the torque will not always follow the voltage curve. This has the effect that the the torque will not increase or decrease linearly.

When the softstarter is given a start signal, the softstarter quickly increases the voltage to the Initial voltage level to set Start ramp initial level. The softstarter then controls the output voltage in a start ramp.

When the output voltage reaches Top of ramp, the softstarter closes the by-pass, see Figure 78.

To reach Top of ramp the following conditions are needed:

• Pre-set Start ramp time have passed, i.e. 100% output voltage.

• The current is below 1.2 x nominal motor current.

The Start ramp time is the time it takes to go from Initial voltage level to full voltage. The actual time to reach the

Top of ramp state also depends on the current, which means that the time to reach Top of ramp can be longer than the set Voltage ramp time.

If the motor is to start with a very heavy load, the start ramp time can be longer than usual.

Exampel: If the Start ramp time is set to 2 seconds and the motor is supposed to start a heavy load. This can cause the output current to not go below set 120% of nominal motor current when the pre-set start ramp time is reached.

7.1.2 Voltage stop ramp

When the softstarter is given a stop signal, the softstarter decreases the output voltage to the motor in a quick stop ramp, from full voltage down to set Step down voltage level.

For best performance the step down level shall be set to 80%.

When step down level is reached the softstarter controls the output voltage during pre set Stop ramp time to End voltage level and cuts the output voltage to the motor,

7.2 Torque ramp

When using the Torque ramp, the output voltage is controlled, so that the output torque will follow a predefined optimal torque curve during start and stop ramp.

For Torque start ramp there is four different adjustable torque curves. See description of torque profile parameters for examples on when to use which curve.

The curves are:

• Constant

• Linear

• High inertia

• Progressive

When using the Torque start ramp start, the rotational speed is constant if the set torque curve corresponds to the actual load curve. The output voltage will not increase linearly, as when using the voltage start ramp,

see Figure

80.

The Torque ramp benefits the mechanical starting behaviour of the equipment driven by the motor, to be softer than when using the Voltage start ramp.

For Torque stop ramp there is one fixed torque curve. This fixed torque curve is optmimized for pump applications.

7.2.1 Torque start ramp

When the softstarter is given a start signal, the softstarter makes a quick ramp to set Start ramp initital level. Then the softstarter controls the output voltage so that the output torque will follow a predefined optimal torque curve during pre-set time to 100 % nominal torque.

When the output voltage reaches 100 % nominal voltage

(Top of ramp), the softstarter closes the by-pass.

To reach Top of ramp the following conditions need to be met:

• The output voltage reaches 100 % nominal voltage.

• The current is below 1.2 x nominal motor current.

The time between the start signal and when nominal torque is reached is the start ramp time.

The start ramp time can be longer depending on if the motor is to start with a very heavy load.

Exampel: If the Start ramp time is set to 2 seconds and the motor is supposed to start with a heavy load. This can cause that the output current does not go below set 120% of nominal motor current when the pre-set start rampt time is reached.

7.2.2 Torque stop ramp

When using the Torque stop ramp, the output voltage to the motor is controlled so that the torque will follow a predefined optimal curve from the Step down level to end voltage during stop. This has the benefit that the mechanical stopping behaviour of the equipment driven by the motor, will be much softer than when using voltage ramp.

See Figure 81.

This can be especially useful in pump applications where a sudden stop can cause water hammering and pressure surges.

7.6 Current limit

Current limit sets a maximum value of the starting current output to the motor. The time it takes to reach full voltage can be longer than the set Start ramp Time when Current limit is enabled.

There are three different Current limit functions:

• Normal current limit

• Dual current limit

• Ramp current limit

WARNING

If the load is very heavy, current limit can prevent the current to decrease below the set current level and cause overheating.

Normal current limit

When using Normal current limit and the set current limit is reached, the output voltage stays stable until the current level falls below the set current limit. Then the start ramp continues.

Dual current limit

Dual current level has two settable current limit levels.

When the first current limit is reached, the current limit will keep the output voltage constant untill the configured time has passed or the current decreases. If the current decreases, the softstarter continues the voltage ramp. If the second configured Current limit time, has passed and the current has not decreased, the softstarter increases the current to the second level, and then it continues the voltage ramp. See Figure 82.

If the current reaches the second current limit, the softstarter will behave as for the normal current limit.

Dual current limit can be used as a back-up function to prevent overheating.

7.8 Slow speed

Slow speed is an individual function, or a pre-start function to run the motor with low voltage output. This feature can, for example, be used to position a traverse or millband.

This function can be operated via the HMI, IO or fieldbus.

Slow speed has four pre-defined speeds:

• Fast jog

• Jog

• Creep

The motor strength can be adjusted with separate parameters. Choose a suitable value for the application.

INFORMATION

Too high value of the motor strength could cause oscillations and if too low the motor may not start.

It is possible to run the motor in both the forward and reverse direction, with different slow speed speeds in both directions.

When a Slow speed signal is given, the motor will accelerate up to a constant speed, that is slower than the nominal speed, for as long as the slow speed signal remains active. When the Slow speed signal is deactivated, the softstarter immediately cuts the voltage applied to the motor and the motor stops.

For navigation, see chapter 6.2.4 Motor Jog

7.9 Motor heating

Motor heating can be used as a pre-start function to heat the motor before actual start without any rotation to the motor. It can also be used as an individual function operated from a digital input or fieldbus.

The softstarter supplies a current to the engine, without reaching the torque level that starts the engine. This warms up the engine without starting it.

7.10 Sequence start

The softstarter can start up to three different motors sequentially, sequence 1, 2 and 3. This is suitable when setting up the softstarter with different applications.

Choose the parameter set via input signal to the softstarter.

Parameter settings and physical connections for programmable inputs must correspond.

For connections, see chapter 5.

Parameters set for sequence start 1, 2 and 3 are equal.

If the softstarter trips for any reason, and the trip is supposed to stop the motor, all motors will be stopped.

Example: Start 1, (Start mode seq 1) is configured to Run 1 relay , (K4,K5 or K6) the relay closes when the startsignal is given, which leads to a power transfer. This can switch between softstarters and their specific parameter settings.

7.11 Automatic restart

The softstarter automatically restarts the motor after a fault has occurred.

The primary requirement is that if a fault or protection has been asserted, the softstarter shall automatically restart the motor in order to ensure an uninterrupted process.

The event is reset only after the Auto-reset delay time has transpired. If Auto-restart is enabled, an internal start signal is given and the fault relay is not directly activated. This is because the fault relay can sometimes be connected to a breaker located upstream .

Until a successful start is carried out, several attempts to restart are made with a fixed time interval between each.

During the time between each restart, the start digital input signal is ignored.

I f the fault still remain by the time a restart is made, this will be seen as a failed restart attempt.

The fault relay will only be activated after the maximum number of restarts have failed.

If a stop signal is given, the auto-restart sequence is aborted and the fault re lay is not activated.

Automatic restart is configured with the following parameters:

7.12.1 Digital inputs (DI)

The softstarter is equipped with five digital inputs for basic control of the unit.

The five digital inputs are terminal 13,14,15,16 and 17.

The Inputs are named:

• Start

• Stop

• In0

• In1

• In2

Start and Stop inputs are fixed to start and stop function and can not be configured.

In0, In1 and In2 are programmable inputs. Functions can be related to the physical signal through a drop down menu on the HMI.

The programmable options are:

• None - No function on the digital input.

• Reset - Fault/protection reset.

• Enable - TBD

• Slow speed forward - While the digital input is high, the motor will slowly move forward.

• Slow speed reverse - While the digital input is high, the motor will slowly move in the reverse direction.

• Motor heating - While the digital input is high, the motor heating is active.

• Stand still brake - While the digital input is high, the stand still brake is active.

• Start reverse - TBD

• User defined protection - When activated (the protection can be programmed to be active low or high) the user defined protection will be activated.

• Fieldbus disable control - When the digital input is set high, the motor cannot be controlled from the fieldbus. Instead the start/stop digital input must be used, or the HMI.

• Start 1 - Start motor 1. See chapter 7.10 Sequence start.

• Start 2 - Start motor 2. See chapter 7.10 Sequence start.

• Start 3 - Start motor 3. See chapter 7.10 Sequence start.

7.12.4 Temperature sensor

Temperature inputs

There is one temperature input. The user can set three different types of temperature sensors:

• PTC

• PT100

• Bi-metal switch

These can be connected to different protections.

A protection can be set to switch on if a particular temperature occurs.

PTC

The PTC temperature input can measure a motor temperature in the range of -25° to 250°. The PTC measuring shall follow the standard for a Mark-A detector according to IEC60947-8.

The temperature control system has a short circuit detector that will detect if the input resistance is less than

10 ohm. This detector will only work if the total length of the connected cable is less than 10 ohm i.e. about 140 m with 0,5 mm² cable, 240m with 1,0 mm² cable and 440m with 1,5 mm². If a short circuit is detected then the error is reported to the user.

It is possible to detect if a sensor is connected to the softstarter.

It is also possible to enable the temperature measurement and to manual reset, automatic reset or get indication only.

PT100

The softstarter has a 3-wire PT100 input that can be combined and share terminals with the PTC input.

The trip temperature is set by the user. The maximum trip temperature is 250° and lowest is -25°.

The PT100 measuring shall have an accuracy of +/-3° with three wires measuring if the three connecting cables have the same resistance.

If a short circuit is detected then the error is reported to the user. The softstarter is also be able to detect if a sensor is connected to the softstarter.

It is possible to enable the temperature measurement. It is also possible to perform a manual reset, automatic reset or to indications only.

Bi-metal switch

It is possible to combine temperature input with bi-metal switches or thermo click elements for detecting over temperature. These temperature sensors behave like a switch that opens or close at the trip temperature. Both types (NO – normally open or NC – normally closed) is supported and short circuit detection must be turned off since it is not applicable. The maximum current through the bi-metal switches is 100 mA.

Temperature sensor is configured with the following parameters: See chapter 7.14.14

7.13 Fieldbus

PSTX has one Anybus port, one fieldbus plug adaptor port (FBPA), and one Modbus RTU port. Only one bus at the time can be used. i.e. the user cannot connect the softstarter to multiple fieldbuses.

The port used for Modbus RTU is a multifunction port that can also be used for connecting an Extension IO module.

If an Extension IO module is required it is not possible to use the port for Modbus RTU, use an Anybus Modbus

RTU module instead.

In the IP-based fieldbuses, such as Modbus TCP, the user have to specify IP address, gateway, subnet mask and

DHCP client.

Fieldbus type

When fieldbus communication is used, the present type of fieldbus must be selected.The following fieldbus types are available in the softstarter:

• Modbus-TCP

• Modbus-RTU

• DeviceNet

• Profibus

• EtherNet/IP

Fieldbus control

If the softstarter is going to be used with fieldbus communication, the fieldbus interface must be enabled before any action can be taken.

Fieldbus address

If the softstarter is going to be used with fieldbus communication, set a fieldbus address for the softstarter.

Select a suitable, and unoccupied number as the address.

CAUTION

The motor may start unexpectedly if there is a start signal present when performing any of the actions listed below.

• Switching from one type of control to another (fieldbus control / hardwire control).

• Remember that when Fieldbus auto disable is active, this switch can be done automatically.

• Re-programming of the programmable inputs.

• Reset all Settings (programmable input set to Enable).

Fieldbus auto disable

With fieldbus auto enabled, the control of the softstarter will automatically switch over from the fieldbus to the hard wire inputs, if the fieldbus malfunctions for instance due to power loss or broken cable. When the fieldbus starts working again, the control is automatically switched back to the fieldbus.

Fieldbus Inputs/Outputs

Functions set in the softstarter as Fieldbus digital inputs

(DI) are in fact the digital inputs to the PLC i.e. the data flow from the softstarter through the network to the PLC.

Fieldbus digital outputs (DO) are not configurable. The output (DO) describes data flow from the network to the softstarter i.e. appears as an input, from the softstarter point of view.

Fieldbus communication is configured with the following parameters:

7.14 Event groups

Event groups consists of supervision functions divided in seperat lists in the HMI.

Supervision functions are functions to indicate when an event occurrs to the motor.

There are three different types of supervision functions:

• Faults

• Warnings

• Protections

The supervision functions generate events based on different conditions in the motor and in the softstarter itself. Each individual event can be assigned to one or more Event groups. An Event group can be mapped to a relay output or/and a fieldbus signal.

For each supervision function there is a parameter for assigning the corresponding event to one or more Event groups.

In PSTX there are seven Event groups, numbered from 0 to 6. All event functions are set as default to one Event group.

There are seven event groups that can be used in whatever way appropriate to the user. Event groups

4-6 will be completely unassigned by default and are convenient to use for custom applications. The other groups will have (or may have in the future) events assigned to them by default.

Example:

7.15 Protections

The softstarter is equipped with a number of protection functions to protect the softstarter, motor and other equipments.

A protection can be completely turned off, configured to stop the motor, or indicate that the event has occurred.

There are two options if the protection shall stop the motor: either a manual reset is required, or the softstarter will automatically reset the protection when the protection goes inactive, i.e. when the conditions that triggered the event are gone.

In addition to the type of operations mentioned above, which are avilable for all protections, some protections have more options.

When the protection acts as a warning, it will indicate that something is wrong.

When the protection acts as a fault, it will stop the motor when fault occur (Direct stop).

Protections can be enabled or disabled by the user.

The protection parameters can only be configured if the protection is activated.

When any of the protections signals a risk of damage, the following basic actions will be performed:

- Protection LED will light up

- The type of event is displayed

- The type of event is logged on the event list

Protections can be set to have automatic reset or manual reset. For every protection, there is parameter options called Operation, which can be set as:

• Stop-Automatic – The engine stops and reset automatic after the fault condition has been corrected*.

• Stop-Manual – The engine stops and have to be reset manually after the fault condition has been corrected*.

• Off

• Indication

* You cannot reset a fault before the fault condition is corrected. Example: If stop-manual is set at EOL

Fault (engine is too warm) you can only reset the softstarter once the engine has cooled down to the right temperature.

Protections can be set to an Event group by a parameter option called

Out. The Event group can be configured for relay output to control other devices in an application.

As default all parameters are set to one Eventgroup.

7.17 Faults

The softstarter is equipped with a number of fault detection functions to protect the softstarter.

Faults detection is always running as default and cannot be turned of by the user. If a signal is malfunctioning in the softstarter, the motor or in the power network level, a fault will occur. Supervised faults can be divided in internal and external faults.

Internal fault:

There has been a fault in equipment connected to the softstarter, see chapter 10 Troubleshooting, and contact

ABB sales office if necessary.

External fault:

There has been a fault in the softstarter, see chapter

10 Troubleshooting, and contact ABB sales office if necessary.

When a fault occur, the type of fault will be described on the home screen, the red Fault LED light will illuminate, and the powersupply to the motor which is connected to the softstarter will be turned of (Direct stop).

When any of the faults are detected these basic actions will be performed:

- Fault LED will light up

- The type of event is displayed

- The type of event is logged on the event list

Faults cannot be configured in other way then to set the reset mode to stop-automatic or stop-manual.

Faults can be set to have automatic reset or manual reset.

For every fault, there is parameter options called

Operation, which can be set as:

• Stop-Automatic

– The engine stops and resets automatically after the fault condition has been corrected*.

• Stop-Manual – The engine stops and has to be reset manually after the fault condition has been corrected*.

* Faults cannot be reset before the fault condition is corrected.

Example: If stop-manual is set at EOL Fault (engine is too warm) the softstarter can only be reset once the engine has cooled down to the right temperature.

When the engine has reached below a certain temperature, the fault condition will be gone, and then reset. The fault will be cleared from the fault list and the engine can be started again.

Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: [email protected]

Faults can be set to an Event group by a parameter option called Out. The Event group can be configured for relay output to control other devices in an application.

As default all parameters are set to one Eventgroup.

At occurrence, the following action is decided based on user preference:

• Stop motor and manually reset is required

• Stop motor and automatic reset is performed

• Only indication will be given ( fire pump mode only)

• Auto-restart possibilities

In addition to the basic actions, depending on the fault, further actions can be added or the basic actions can be modified. If several faults occur they are all stored in a sequence and an individual reset for each fault must be done if manual reset is selected.

Fire pump – Faults disabled:

The normal operation of the softstarter when a fault is detected is to do a direct stop.

If the the Fire pump is enabled and a fault is detected, the softstarter will try to run the motor according to the start and stop signals, ignore safety, and continue to run regardless of consequences.

The softstarter can manage to run the motor depending on what fault is detected.

7.17.1 Internal faults

7.18 Special feature

This chapter describes features that are available to all users, but beyond the normal range of use for the softstarter.

The features are:

• Line contactor close time

• TOR relay delay time

• Start without start command

• Step down level

• System mode

• Limp mode

• Motor connection

7

7.18.3 Line contactor close time

This feature allow time for the line contactor to close before the softstarter assumes that it has correct three phase supply.

This is useful to avo id timing problems that can lead to unnecessary trips on for example Phase loss protection.

Line contactor close time is configured with the following parameters:

Parameter

28.02

Line contactor close time

Description

Allow time for line contactor to close. Sets the time between start signal and beginning of diagnostic measurements.

7.18.6 Start without start command

This feature could be used for a customer that would like to use the softstarter in the same way as a contactor is used, i.e. as soon as the control supply to the softstarter is turned on the softstarter will automatically start the motor. No wiring of start and stop signals is needed.

Start without start command is configured with the following parameters:

Parameter

28.04

Start without start command

Description

Starts the motor without needing an external start command.

Setting range

Off, On

Default value

Off

7.18.7 Step down level

When the softstarter is given a stop signal the softstarter first decreases the output voltage to the motor in a quick stop ramp, from full voltage down to set Step down voltage level. Then the softstarter controls the output voltage in a stop ramp.

It is only meaningful to adjust the step down level for torque control. When using voltage ramp it shall be set to

80%. Depending on the load it can be necessary to adjust the step down level.

Step down level is configured with the following parameters:

Parameter

28.05

Step down level

Description

Set the level from where the stop ramp initiates.

Short circuit fault

Shunt fault

Unspecified fault

Heat sink fault

10

Open circuit thyristor fault

Faulty usage

Faulty connection

Possible cause

Excessive disturbances in the operational supplying network.

Short power loss on all three phases in the operational network.

The thyristors are overheated.

One or several thyristors are shorted.

Solution

• Check for harmonics or frequency disturbancein the supply network and correct supplying operational network.

• Check and correct supplying operational network.

Check the starting conditions and the fans.

Decrease current limit if possible.

Let the thyristors cool down before restart.

Check and contact your ABB sales office for replacement kit.

The softstarter can not stop the motor due to internal short circuit.

By-pass relay closed, due to inaccurate handling.

(PSTX30...170 only).

N/A

The heat sink temperature is too high. If the fault remains after reset, the heat sink is too warm and needs to cool down.

One or several thyristors are not conducting.

The Operational voltage is below

175 V.

The motor is too small.

(Current is out of measuring range.)

Inside delta motor connection when trying to jog forward, jog backward, heat motor or doing stand still break.

Motor connection unknown when trying to start motor.

Contact ABB sales office for service.

Switch off operational voltage and control supply voltage. Switch on voltage in correct succession.

1. Control supply voltage on terminals

1 and 2. See chapter 5.1.2 Control supply and control circuit.

2. Wait 4 seconds, and then switch on operational voltage on terminals

L1, L2 and L3.

If same fault remains, contact your

ABB Sales Office.

Disconnect and reconnect the supply voltage (Us) and make a restart.

If same fault remains, contact your ABB sales office.

Check that the fans are working in a proper way.

Check that cooling airways are free from dirt and dust.

Check that the ambient temperature is not too high.

Contact your ABB sales office for service.

Check that the softstarter corresponds to the motor size.

For test purposes it is possoble to use small motor mode. See chapter 7 Functions.

Do not use named functions with Inside delta motor connection.

Check motor connection.
