Fault F17 Input Phase Loss
FRN 6.xx and later. Excessive DC bus ripple voltage detected. See d329 (DC Bus Ripple V). Check incoming power for a missing phase or blown fuse. If drive is used intentionally with single phase input, apply output derating of 35% actual drive rating.
Fault F2 Auxiliary Input
Auxiliary input interlock is open. 1. Check remote wiring. 2. Verify communications programming for intentional fault.
Fault F29 Analog Input Loss
An analog input is configured to fault on signal loss. A signal loss has occurred. Configure with T072 (Analog In Loss). 1. Check parameters. 2. Check for broken or loose connections at inputs.
Fault F3 Power Loss
FRN 5.03 and earlier only. The DC bus voltage fell below under voltage level within 200 ms of a start command, DC bus ripple voltage in excess excessive, or an input phase loss has been detected. 1. Monitor the incoming AC line for low voltage or line power interruption. 2. Check input fuses.
Fault F32 Fan Fdbk Loss
FRN 6.xx and later. A loss of fan feedback has been detected. (Frames E and F only). Make sure cooling fans are clear of debris and spinning freely. Replace fan if necessary.
Fault F33 Auto Rstrt Tries
Drive unsuccessfully attempted to reset a fault and resume running for the programmed number of A163 (Auto Rstrt Tries). Correct cause of the fault and manually clear.
Fault F38 Phase U to Gnd
A phase to ground fault has been detected between the drive and motor in this phase. 1. Check the wiring between the drive and motor. 2. Check motor for grounded phase. 3. Replace drive if fault can not be cleared.
Fault F39 Phase V to Gnd
A phase to ground fault has been detected between the drive and motor in this phase. 1. Check the wiring between the drive and motor. 2. Check motor for grounded phase. 3. Replace drive if fault can not be cleared.
Fault F4 UnderVoltage
DC bus voltage fell below the minimum value. 1. Monitor the incoming AC line for low voltage or line power interruption. 2. Check input fuses.
Fault F40 Phase W to Gnd
A phase to ground fault has been detected between the drive and motor in this phase. 1. Check the wiring between the drive and motor. 2. Check motor for grounded phase. 3. Replace drive if fault can not be cleared.
Fault F41 Phase UV Short
Excessive current has been detected between these two output terminals. 1. Check the motor and drive output terminal wiring for a shorted condition. 2. Replace drive if fault cannot be cleared.
Fault F42 Pahse UW Short
Excessive current has been detected between these two output terminals. 1. Check the motor and drive output terminal wiring for a shorted condition. 2. Replace drive if fault cannot be cleared.
Fault F43 Phase VW Short
Excessive current has been detected between these two output terminals. 1. Check the motor and drive output terminal wiring for a shorted condition. 2. Replace drive if fault cannot be cleared.
Fault F48 Params Defaulted
The drive was commanded to write default values to EEPROM. 1. Clear the fault or cycle power to the drive. 2. Program the drive parameters as needed.
Fault F5 OverVoltage
DC bus voltage exceeded the maximum value. 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.
Fault F6 Motor Stalled
Drive unable to accelerate motor. Increase P039 - A147 (Accel Time x) or reduce load so drive output current does not exceed the current set by parameter A179.
Fault F63 SW OverCurrent
Programmed A183 (SW Current Trip) has been exceeded. Check load requirements and A183 (SW Current Trip) setting.
Fault F64 Drive Overload
Drive rating of 110% for 1 minute or 150% for 3 seconds has been exceeded. Reduce load or extend Accel Time.
Fault F7 Motor Overload
Internal electronic overload trip. 1. An excessive motor load exists. Reduce load so drive output current does not exceed the current set by parameter P033 (Motor OL Current). 2. Verify A170 (Boost Select) setting.
Fault F70 Power Unit
Failure has been detected in the drive power section. 1. Cycle power. 2. Replace drive if fault cannot be cleared.
Fault F71 Net Loss
The communication network has faulted. 1. Cycle power. 2. Check communications cabling. 3. Check network adapter setting. 4. Check external network status.
Fault F8 Heatsink OvrTmp
Heatsink temperature exceeds a predefined value. 1. Check for blocked or dirty heatsink fins. Verify that ambient temperature has not exceeded 45°C (113°F) for IP30/NEMA 1/UL Type 1 installations or 50°C (122°F) for IP20/Open type installations. 2. Check fans.
Fault F81 Comm Loss
RS485 (DSI) port stopped communicating. 1. Check RS485 wiring connection. 2. Check if a communications adapter of HIM was disconnected. 3. Increase C106 (Comm Loss Time) to an appropriate time for application. 4. Change C105 (Comm Loss Action) to a value other than 0 (fault) if appropriate for the application.
Fault F94 Function Loss
P036 (Start Source) is set to setting 6. The input to terminal 01 has been opened. Close input to terminal 01 and re-start the drive.
