Fault CodesCause & Solution
F0001
OverCurrent 		Cause:
– Motor power (P0307) does not correspond to the inverter power (r0206)
– Motor leads are too long
– Motor lead short circuit
– Earth faults

Soultion:

Check the following:
– Motor power (P0307) must correspond to inverter power (r0206)
– Cable length limits must not be exceeded
– Motor cable and motor must have no short-circuits or earth faults
– Motor parameters must match the motor in use
– Value of stator resistance (P0350) must be correct
– Motor must not be obstructed or overloaded
– Increase the ramp time
– Reduce the boost level (V/f control: P1311 & P1312, Vector control: P1610 & P1611)
F0002
OverVoltage 		Cause:

– DC-link controller disabled (P1240 = 0)
– DC-link voltage (r0026) exceeds trip level (P2172)
– Overvoltage can be caused either by too high main supply voltage or if motor is in regenerative mode. Regenerative mode can be caused by fast ramp downs or if the motor is driven from an active load.

Check the following:
– Supply voltage (P0210) must lie within limits indicated on rating plate
– DC-link voltage controller must be enabled (P1240) and parameterized properly
– Ramp-down time (P1121) must match inertia of load
– Required braking power must lie within specified limits

NOTE: Higher inertia requires longer ramp times; otherwise, apply braking resistor.
F0003
UnderVoltage 		Cause:

– Main supply failed
– Shock load outside specified limits

Soultion:

Check the following:
– Supply voltage (P0210) must lie within limits indicated on rating plate
– Supply must not be susceptible to temporary failures or voltage reductions
– Enable kinetic buffering (P1240 = 2)
F0004

Temperature 		Cause:
– Ventilation inadequate
– Ambient temperature is too high

Soultion:

Check the following:
– Load conditions and duty cycle must be appropriate
– Fan must turn when inverter is running
– Pulse frequency (P1800) must be set to default value

(4) I/O board is not properly inserted
– Frame sizes A to C (1),(2),(3),(4)
– Frame sizes D to E (1),(2),(4)

A0711
CB configuration
error		Cause: CB (communication board) reports a configuration error.

Solution:

1. Check CB parameters.
A0910
Vdc-max
controller
de-activated		Cause: Vdc max controller has been de-activated, since controller is not capable of keeping DC-link voltage (r0026) within limits (P2172).
– Occurs if main supply voltage (P0210) is permanently too high
– Occurs if motor is driven by an active load, causing motor to go into regenerative mode
– Occurs at very high load inertias, when ramping down

Solution:

Check the following:
– Input voltage (P0210) must lie within range
– Load must be match
A0911
Vdc-max
controller
active		Cause: Vdc max controller is active; so ramp-down times will be increased automatically to keep DC-link voltage (r0026) within limits (P2172).
A0912
Vdc-min
controller
active		Cause: Vdc min controller will be activated if DC-link voltage (r0026) falls below minimum level (P2172). The kinetic energy of the motor is used to buffer the DC-link voltage, thus causing deceleration of the drive! So short mains failures do not necessarily lead to an undervoltage trip.
A0920
ADC parameters
not set properly		Cause: ADC parameters should not be set to identical values, since this would produce illogical results.

Fault value =
0: Parameter settings for output identical
1: Parameter settings for input identical
2: Parameter settings for input do not correspond to ADC type
A0921
DAC parameters
not set properly		Cause: DAC parameters should not be set to identical values, since this would produce illogical results.

Fault value =
0: Parameter settings for output identical
1: Parameter settings for input identical
2: Parameter settings for output do not correspond to DAC type
A0922
No load
applied to
inverter		Cause: No Load is applied to the inverter. As a result, some functions may not work as under normal load conditions.

Solution: This alarm also comes when you run drive without motor or rating of motor is small as compare to drive.
A0923
Both JOG Left
and JOG Right
are requested		Cause: Both JOG right and JOG left (P1055/P1056) have been requested. This freezes the RFG output frequency at its current value.
A0936
PID Autotuning
Active		Cause: PID Autotuning (P2350) selected or running.

Solution: This is a informative warning.
A0952
Belt Failure

Check the following:
1. No breakage, seizure or obstruction of drive train.

P2183 (threshold frequency f2)
P2184 (threshold frequency f3)
P2185 (upper torque threshold 1)
P2186 (lower torque threshold 1)
P2187 (upper torque threshold 2)
P2188 (lower torque threshold 2)
P2189 (upper torque threshold 3)
P2190 (lower torque threshold 3)
P2192 (delay time for permitted deviation)
