Fault
Code
Description Cause Troubleshooting Remarks
Er10
System
overloaded
1. The guide rail of the
elevator door is blocked by
stuff.
2. The load is too heavy.
1. Check the guide rail of
the elevator door.
2. Reduce the load.
Er11
Motor
overload
1. The guide rail of the
elevator door is blocked by
stuff.
2. The load is too heavy.
3. The value of F8-14 is
too small.
1. Check the guide rail of
the elevator door.
2. Reduce the load.
3. Set F8-14 to a proper
value.
A large setting of
F8-14 may cause
motor overheat.
Use the default
value.
Er13
Power output
phase loss
1. The wiring of the main
circuit is loose on the
output side.
2. The motor is damaged.
1. Check the wiring.
2. Rectify faults of the
motor.
The controller
decelerates and
stops.
Er14
Module
overheat
1. The ambient
temperature is too high.
2. The fan is damaged.
3. The air lter is blocked.
1. Reduce the ambient
temperature.
2. Replace the fan.
3. Clear the air lter.
The controller
decelerates
and stops, and
automatically
resets after the
temperature
becomes
normal.
Er16
EEPROM
fault
An EEPROM reading or
writing abnormality occurs.
Contact the agent or
vendor.
Er18
Current
detection fault
The control board is
abnormal.
Contact the agent or
vendor.
Er19
Motor auto-
tuning timeout
1. The motor parameters
are incorrectly set.
2. Parameter identication
times out.
2. The encoder for the
PMSM is abnormal.
1. Enter the motor
parameters correctly.
2. Check the lead wire of
the motor.
3. Check wiring of the
encoder and ensure the
PPR is set correctly.
Er20 Encoder fault
1. The encoder model is
improper.
2. Wiring of the resolver is
incorrect.
1. Use an open-collector
ABZ phase resolver.
2. Eliminate wiring
problems.
