Failure description Potential causes Solutions
Enable auto-tuning function during
motor spining Perform auto-tuning after the
motor stops to rotate
Auto-tuning overtime
Check whether motor wirings
are well connected
Length of motor wiring within
100m
9 E.AUt Auto-tuning failure
Incorrect setting of motor parameters
in group P9
Please reset the parameters
according to the nameplate
parameters on the motor.
Output over current
Check whether the motor the
output connection is short
circuited, whether the ground is
short circuited and whether the
load is too heavy.
10 E.FAL Module protection
DC terminal overvoltage
Check the mains power supply
and whether the large inertia
load has no function of quick

brake.
Ambient over-temperature
Lower the ambient temperature
and strengthen ventilation and
heat dissipation.
Blockage of air duct
Clean the dusts, wools and other
foreign objects in the air duct.
Fan failure
Check whether fan wirings are
well connected.
Replace a new fan of the same
model.

13 E.oL1
Drive overload
protection
The motor's power goes beyond the
driver's maximum drive current Replace to drive with proper
model
Input power under voltage Check input power supply
Motor rotation is blocked or load
mutation occurs
Prevent the motor rotation from
blocking and reduce the load
