description
Fault cause Disposal way Sort
Err 16
Encoder
error
1 .start position error 2
.torque deviation too big
.3 .the feedback speed
exceeds 25% of the motor
rated speed
1 .check the encoder loop
Err 17 E17
Encoder
singal verify
abnormal
Check the encoder singal
check the encoder
check the encoder wiring
check the PG card witing
check the controller box
and motor grounding

Err 18 E18
Current
detection
fault
Diver control panel is
abnormal;
Please contact with agent
or factory;

Err 19 E19
Motor tuning
fault
1 .Motor parameter setting
is wrong;
2 .Parameter tuning is
overtime;
3 .Synchronous rotate
encoder is abnormal;
1 .Input the right motor
parameter;
2 .Detect motor lead wire;
3 .Detect the rotate
encoder wiring, and make
sure the pulse number per
round is well set .
4 .check whether the
brake is open when runing
without load
5 .whether to release the
inspection button before
the tuning is complete
(synchronous motor)
5
Err 20 E20
Rotary
encoder fault
1 .Rotary encoder model is
suited or not;
2 .Encoder connection
error;
1 .Asynchronous motor
can select push-pull output
or open-collector encoders;
synchronous motor can
select UVW or SIN/COS .
2 .Obviate connection
problem;
5
Err 22 E22
Leveling
and door
area signal
conglutination
fault
Leveling/door area signal
is conglutination or cut off;
Please detect the leveling/
door area sensor and main
control panel input point .
2 .check the leveling flag
install
