Troubleshooting and Diagnostics

Fault Cause Remedy

(1)

Output fault:

Transistor fault

Output short circuit Check motor/motor cable

Acceleration time too short Increase P104, P125

Severe motor overload, due to:

• Mechanical problem

• Drive/motor too small for application

• Check machine / system

• Verify drive/motor are proper size for

application

Boost values too high Decrease P168, P169

Excessive capacitive charging current of

the motor cable

• Use shorter motor cables with lower charging

current

• Use low capacitance motor cables

• Install reactor between motor and drive.

Failed output transistor Contact factory technical support

Output fault: Ground fault Grounded motor phase Check motor and motor cable

Excessive capacitive charging current of

the motor cable

Use shorter motor cables with lower charging

current

Motor Overload fault Excessive motor load for too long • Verify proper setting of P108

• Verify drive and motor are proper size for

application

Flying Restart fault Controller was unable to synchronize with

the motor during restart attempt; (P110

= 5 or 6)

Check motor / load

Single-Phase fault A mains phase has been lost Check mains voltage

Start fault Start command was present when power

was applied (P110 = 0 or 2).

• Must wait at least 2 seconds after power-up

to apply Start command

• Consider alternate starting method (P110).

TB5 (0-10V signal)

Threshold fault

0-10V signal (at TB5) drops below the value

set in P158.

• Check signal/signal wire

• Refer to parameters P157 and P158

(1) The drive can only be restarted if the error message has been reset.
