Auto-Reset/Run type fault. Configure with parameters A092 and A093.
Description
Check remote wiring.
Monitor the incoming line for phase loss or line imbalance. Then, check input line fuse.
Monitor the incoming AC line for low voltage or line power interruption.
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 dynamic brake option.
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/NEMA 1/UL Type 1 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.
An analog input is configured to fault on signal loss. A signal loss has occurred.
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.
The autotune function was either cancelled by the user of failed.
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 A105 [Comm Loss Action].
Cycle power. Replace drive if fault cannot be cleared.
