Possible Cause Solution
Fault Type
Motor auto-tuning
error
E22.00
The stator resistance
obtained through auto-
tuning exceeds the allowed
range.
Check whether the rated motor voltage and current
are correctly set, and set F1-02 (rated motor voltage)
and F1-03 (rated motor current) according to the
motor nameplate.
Perform auto-tuning after the motor stops.
Axis fault
E22.01
The rotor resistance of the
asynchronous motor
obtained through auto-
tuning exceeds the allowed
range.
Axis fault
E22.02
The no-load current and
mutual inductance of the
asynchronous motor
obtained through auto-
tuning exceed the allowed
range. If such an alarm is
generated, the AC drive
calculates no-load current
and mutual inductance
based on known parameters,
which may be different from
the optimal values.
Set motor parameters in group F1 according to the
motor nameplate.
Before auto-tuning, ensure that the motor has no
load.
Axis fault
E22.03
The back EMF of the
synchronous motor obtained
through auto-tuning exceeds
the allowed range.
Ensure that the rated motor voltage (F1-02) is set
according to the motor nameplate.
Before auto-tuning, ensure that the motor has no
load.
