Table 22 — Siemens VFD Low Ambient Temperature Controller Fault Messages
FAULT
F0001 • Motor power does not correspond to the
Overcurrent inverter power
• Motor lead short circuit
• Ground fault
F0002 • DC-link voltage (r0026) exceeds trip level
Overvoltage (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
F0003 • Main supply failed
Undervoltage • Shock load outside specified limits
F0004 • Ambient temperature outside of limits
Drive • Fan failure
Overtemperature
F0005 • Drive overloaded
2
Drive I t • Duty cycle too demanding
• Motor power (P0307) exceeds drive power
capability (P0206)
F0011 • Motor overloaded
Motor • Motor data incorrect

POSSIBLE CAUSES TROUBLESHOOTING
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).
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
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
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.
Check the following:
1. Load duty cycle must lie within specified limits
2. Motor power (P0307) must match drive power (P0206)
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
2
5. Check parameter for motor I t warning level
1. Check if the motor is connected to the drive
2. Check that the motor data has been entered correctly
1. Factory reset and new parameters set
2. Replace drive
Replace drive
1. Acknowledge fault
2. Replace drive if repeated
1. Check connections to the communications board
2. Check the master
1. Check connections to the communications board
2. Check the master
1. Check connections to the communications board
2. Check the master
Check connection to analog input
Disable terminal input for fault trigger
1. Run self test routines
2. Replace drive
1. Change value of P2268
2. Adjust feedback gain
1. Change value of P2267
2. Adjust feedback gain
1. Inverter may run but certain actions will not function correctly
2. Replace drive
