Your complete drive solutions for process industries

Our industrial drives are available both as complete AC drives and as modules to meet your requirements as a user, OEM or system integrator. Single drive modules configuration contains a rectifier, DC link and an inverter in one single AC drive unit. They can be installed without any additional cabinet or enclosure, available in wall-mounted, freestanding and cabinet-built constructions. They are specifically designed for industrial applications in process industries such as the pulp & paper, metals, mining, cement, power, chemical, and oil & gas.

Highlights

• IP21 and IP55 enclosure classes
• Direct torque control (DTC) as standard
• EMC filter, choke and brake chopper
• Supports a wide range of fieldbus protocols
• Flexible I/O and encoder options

Check pulse encoder and its wiring.

Check pulse encoder interface module and its wiring.

 

Fault : ENCODER ERR

Cause : Communication fault between pulse encoder and pulse encoder interface module and between module and drive

Check pulse encoder and its wiring, pulse encoder interface module and its wiring and parameter group 50 ENCODER MODULE settings.

 

Fault : INV OVERTEMP

Check converter module cooling air flow and fan operation.

Cabinet installation: Check cabinet air inlet filters. Change when necessary. See appropriate hardware manual.

Modules installed in cabinet by user: Check that cooling air circulation in cabinet has been prevented with air baffles. See module installation instructions.

Check inside of cabinet and heatsink of converter module for dust pick-up. Clean when necessary.

Reset and restart after problem is solved and let converter module cool down.

Check Fault Function parameters.

 

Fault : START INHIBI

Cause : Safe torque off has been activated during motor run or motor start command has been given when Safe torque off is active.

Or: Optional start inhibit hardware logic is activated.

What to do :

Close Safe torque off switch. If switch is closed and fault is still active, check power supply at ASTO board input terminals. Replace ASTO board.

Or: Check start inhibit circuit (AGPS board).

 

Fault : UNDERLOAD

Cause : Motor load is too low due to e.g. release mechanism in driven equipment.

What to do :

Check for problem in driven equipment.

Check Fault Function parameters.

 

 

Warning 

 

 

Warning : ACS800 TEMP

Cause : Drive IGBT temperature is excessive. Fault trip limit is 100%.

What to do :

Check ambient conditions.

Check air flow and fan operation.

Check heatsink fins for dust pick-up.

Check motor power against unit power.

 

Warning : BATT FAILURE

Cause : APBU branching unit memory backup battery error caused by

- incorrect APBU switch S3 setting

- too low battery voltage.

What to do :

With parallel connected inverters, enable backup battery by setting actuator 6 of switch S3 to ON.

Replace backup battery.

 

Warning : BR OVERHEAT

Cause : Brake resistor overload

What to do :

Stop drive. Let resistor cool down.

Check parameter settings of resistor overload protection function (see parameter group 27 BRAKE CHOPPER).

Check that braking cycle meets allowed limits.

 

Warning : COMM MODULE

Cause :Cyclical communication between drive and master is lost.

What to do :

Check status of fieldbus communication. See chapter Fieldbus control, or appropriate fieldbus adapter manual.

Check parameter settings:

- group 51 COMM MODULE DATA (for fieldbus adapter)

- group 52 STANDARD MODBUS (for Standard Modbus Link).

Check Fault Function parameters.

Check cable connections.

Check if master can communicate.

 

Warning : DC BUS LIM

Cause : Drive limits torque due to too high or too low intermediate circuit DC voltage.

What to do :

Informative alarm

Check Fault Function parameters.

 

 

Warning : EARTH FAULT

Cause : Drive has detected load unbalance typically due to earth fault in motor or motor cable.

What to do :

Check there are no power factor correction capacitors or surge absorbers in motor cable.

Check that there is no earth fault in motor or motor cables:

- measure insulation resistances of motor and motor cable.

If no earth fault can be detected, contact your local ABB representative.
