LEGEND NOTE: To reset the fault code, one of the following methods can be used:
1. Cycle the power to the drive.
2. Press the button on the operator panel.
FAULT POSSIBLE CAUSES TROUBLESHOOTING
F0001
Overcurrent
• Motor power does not correspond to the
inverter power
• Motor lead short circuit
• Ground fault
Check the following:
1. Motor power (P0307) must correspond to inverter power (P0206)
2. Motor cable and motor must have no short-circuits or ground faults
3. Motor parameters must match the motor in use
4. Motor must not be obstructed or overloaded
After Steps 1-4 have been checked, increase the ramp time (P1120) and reduce the
boost level (P1310, P1311, P1312).
F0002
Overvoltage
• DC-link voltage (r0026) exceeds trip level
(P2172)
• Overvoltage can be caused either by too high
main supply voltage or if motor is in regenera-
tive mode
• Regenerative mode can be caused by fast
ramp downs or if the motor is driven from an
active load
Check the following:
1. Supply voltage (P0210) must lie within limits indicated on rating plate
2. DC-link voltage controller must be enabled (P1240) and have parameters set
correctly
3. Ramp-down time (P1121) must match inertia of load
F0003
Undervoltage
• Main supply failed
• Shock load outside specified limits
Check the following:
1. Supply voltage (P0210) must lie within limits indicated on rating plate
2. Supply must not be susceptible to temporary failures or voltage reductions
F0004
Drive
Overtemperature
• Ambient temperature outside of limits
• Fan failure
Check the following:
1. Fan must turn when inverter is running
2. Pulse frequency must be set to default value
3. Air inlet and outlet points are not obstructed
4. Ambient temperature could be higher than specified for the drive.
F0005
Drive I
2
t
• Drive overloaded
• Duty cycle too demanding
• Motor power (P0307) exceeds drive power
capability (P0206)
Check the following:
1. Load duty cycle must lie within specified limits
2. Motor power (P0307) must match drive power (P0206)
F0011
Motor
Overtemperature I
2
t
• Motor overloaded
• Motor data incorrect
• Long time period operating at low speeds
1. Check motor data
2. Check loading on motor
3. Boost settings too high (P1310,P1311, P1312)
4. Check parameter for motor thermal time constant
5. Check parameter for motor I
2
t warning level
F0041
Stator Resistance
Measurement Failure
Stator resistance measurement failure 1. Check if the motor is connected to the drive
2. Check that the motor data has been entered correctly
F0051
Parameter EEPROM Fault
Reading or writing of the non-volatile parameter
storage has failed
1. Factory reset and new parameters set
2. Replace drive
F0052
Powerstack Fault
Reading of the powerstack information has
failed or the data is invalid
Replace drive
F0060
Asic Timeout
Internal communications failure 1. Acknowledge fault
2. Replace drive if repeated
F0070
Communications
Board Set Point Error
No setpoint received from communications
board during telegram off time
1. Check connections to the communications board
2. Check the master
F0071
No Data for
RS232 Link During
Telegram Off Time
No response during telegram off time via
BOP link
1. Check connections to the communications board
2. Check the master
F0072
No Data from
RS485 Link During
Telegram Off Time
No response during telegram off time via
COM link
1. Check connections to the communications board
2. Check the master
F0080
Analog Input -
Lost Input Signal
• Broken wire
• Signal out of limits
Check connection to analog input
F0085
External Fault
External fault is triggered via terminal inputs Disable terminal input for fault trigger
F0101
Stack Overflow
Software error or processor failure 1. Run self test routines
2. Replace drive
F0221
PI Feedback

PID Feedback below minimum value P2268 1. Change value of P2268
2. Adjust feedback gain
F0222
PI Feedback Above
Maximum Value
PID Feedback above maximum value P2267 1. Change value of P2267
2. Adjust feedback gain
