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.
Check for proper analogue control signal
levels.
Check control wiring.
Check Fault Function parameters.
Consult the documentation or author of the
Adaptive Program.
Wait until download is completed.
With parallel connected inverters, enable
backup battery by setting actuator 6 of switch
S3 to ON.
Replace backup battery.
Stop drive. Let chopper cool down.
Check parameter settings of resistor overload
protection function (see parameter group
BRAKE CHOPPER).
Check that braking cycle meets allowed limits.
Check that drive supply AC voltage is not
excessive.
See parameter group 42 BRAKE
Check connection of brake acknowledgement
signal.
See parameter group 42 BRAKE
Check connection of brake acknowledgement
signal.
Check mechanical brake.
Stop drive. Let resistor cool down.
Check parameter settings of resistor overload
protection function (see parameter group
BRAKE CHOPPER).
Check that braking cycle meets allowed limits.
Continue normal operation.
