F6 Motor Stalled
(1)
Increase [Accel Time x] or reduce load so drive output current does not exceed the current set
by parameter A089 [Current Limit].
F7 Motor Overload
(1)
An excessive motor load exists. Reduce load so drive output current does not exceed the
current set by parameter P033 [Motor OL Current]. Verify A084 [Boost Select] setting.
F8 Heatsink OvrTmp
(1)
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.
F12 HW OverCurrent Check programming. Check for excess load, improper DC boost setting, DC brake volts set too
high or other causes of excess current.
F13 Ground Fault Check the motor and external wiring to the drive output terminals for a grounded condition.
F29 Analog Input Loss
(1)
An analog input is configured to fault on signal loss. A signal loss has occurred.
Check parameters. Check for broken/loose connections at inputs.
F33 Auto Rstrt Tries Correct the cause of the fault and manually clear.
F38 Phase U to Gnd Check the wiring between the drive and motor.
Check motor for grounded phase.
Replace drive if fault cannot be cleared.
F39 Phase V to Gnd
F40 Phase W to Gnd
F41 Phase UV Short Check the motor and drive output terminal wiring for a shorted condition.
Replace drive if fault cannot be cleared.
F42 Phase UW Short
F43 Phase VW Short
F48 Params Defaulted 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.
F63 SW OverCurrent
(1)
Check load requirements and A098 [SW Current Trip] setting.
F64 Drive Overload Reduce load or extend Accel Time.
F70 Power Unit Cycle power. Replace drive if fault cannot be cleared.
F71 Net Loss The communication network has faulted.
Cycle power. Check communications cabling.
Check network adapter setting. Check external network status.
F80 SVC Autotune The autotune function was either cancelled by the user of failed. Restart procedure.
F81 Comm Loss 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].
Connecting I/O Terminal 04 to ground may improve noise immunity.
F91 Encoder Loss Requires differential encoder. One of the 2 encoder channel signals is missing.
Check Wiring.
If P038 [Speed Reference] = 9 “Positioning” and E216 [Motor Fdbk Type] = 5 “Quad Check”
swap the Encoder channel inputs (see page 13) or swap any two motor leads.
Replace encoder.
F100 Parameter Checksum Restore factory defaults.
F111 Enable Hardware DriveGuard Safe-Off Option (Series B) board is installed and the ENBL enable jumper has not
been removed.
Remove the ENBL enable jumper. Cycle power.
DriveGuard Safe-Off Option (Series B) board has failed.
Remove power to the drive. Replace DriveGuard Safe-Off Option (Series B) board.
Hardware Enable circuitry has failed.
Replace drive.
F122 I/O Board Fail Cycle power. Replace drive if fault cannot be cleared.
(1)
Auto-Reset/Run type fault. Configure with parameters A092 and A093.
No. Fault Description
