User Manual.
Description
Check remote wiring. Verify communications programming for intentional fault.
Monitor the incoming AC line for low voltage or line power interruption. Check input fuses.
Monitor the incoming AC line for low voltage or line power interruption. Check input fuses.
Monitor the AC line for high line voltage or transient conditions. Bus overvoltage can also be
caused by motor regeneration. Extend the decel time or install a dynamic brake chopper.
Increase [Accel Time x] or reduce load so drive output current does not exceed the current set
by parameter A089 [Current Limit].
An excessive motor load exists. Reduce load so drive output current does not exceed the
current set by parameter P033 [Motor OL Current].
Check for blocked or dirty heat sink fins. Verify that ambient temperature has not exceeded 40°C
(104°F) for IP 30 installations or 50°C (122°F) for Open type installations. Check fan.
Check programming. Check for excess load, improper DC boost setting, DC brake volts set too
high or other causes of excess current.
Check the motor and external wiring to the drive output terminals for a grounded condition.
Check for load loss (i.e., a broken belt).
Check incoming power for a missing phase or blown fuse. If drive is used intentionally with
single phase input, apply output derating to 35% actual drive rating.
An analog input is configured to fault on signal loss. A signal loss has occurred.
Make sure cooling fans are clear of debris and spinning freely. Replace fan if necessary.
Correct the cause of the fault and manually clear.
Check the wiring between the drive and motor. Check motor for grounded phase.
Replace drive if fault cannot be cleared.
Check the motor and drive output terminal wiring for a shorted condition.
Replace drive if fault cannot be cleared.
The drive was commanded to write default values to EEPROM. Clear the fault or cycle power to
the drive. Program the drive parameters as needed.
Check load requirements and A098 [SW Current Trip] setting.
Reduce load or extend Accel Time.
Cycle power. Replace drive if fault cannot be cleared.
The communication network has faulted.
Restart the Autotune function.
If adapter was not intentionally disconnected, check wiring to the port. Replace wiring, port
expander, adapters or complete drive as required. Check connection. An adapter was
intentionally disconnected. Turn off using C105 [Comm Loss Action].
Close input to terminal 01 and re-start the drive.
Cycle power. Replace drive if fault cannot be cleared.
