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.
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.
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.
Calibration starts automatically. Wait for a
while.
Check status of fieldbus communication. See
chapter Fieldbus control, or appropriate
fieldbus adapter manual.
Check parameter settings:
- group 51 FIELDBUS DATA
adapter)
- group 52 STANDARD MODBUS
Standard Modbus Link).
Check Fault Function parameters.
Check cable connections.
Check if master can communicate.
