Fault
Code
Name Possible Causes Solution Level
Err17
Reference
signal of
the encoder
incorrect
1. The deviation
between the Z signal
position and the
absolute position is too
large.
2. The deviation
between the absolute
position angle and the
accumulative angle is
too large.
1. Check whether the encoder runs
properly.
2. Check whether the encoder
wiring is correct and reliable.
3. Check whether the PG card
wiring is correct.
4. Check whether the grounding of
the control cabinet and the motor is
normal.
5A
Err18
Current
detection fault
The drive control board
fails.
Contact the agent or Monarch. 5A
Err19
Motor auto-
tuning fault
1. The motor cannot
rotate properly.
2. The motor auto-
tuning times out.
3. The encoder for the
PMSM fails.
1. Enter the motor parameters
correctly.
2. Check the motor wiring and
whether phase loss occurs on the
contactor at the output side.
3. Check the encoder wiring and
ensure that the encoder PPR is set
properly.
4. Check whether the brake keeps
released during no-load auto-
tuning.
5. Check whether the inspection
button is released before the PMSM
with-load auto-tuning is finished.
5A
Err20
Speed
feedback
incorrect
1. The encoder model
does not match the
motor.
2. The encoder wiring
is incorrect.
3. The current keeps
large during low-speed
running.
1. Check whether F1-00 is set
correctly.
2. Check the encoder wiring.
3. If Err20 is reported in the stop
state, check whether signal lines C,
D of the SIN/COS encoder or signal
lines U, V, W of the UVW encoder
are broken.
4. Check whether the encoder is
stuck mechanically during running.
5. Check whether the brake keeps
released during running.
5A
Err22
Leveling signal
abnormal
The leveling position
deviation is too large.
1. Check whether the leveling and
door zone sensors work properly.
2. Check the installation verticality
and depth of the leveling plates.
3. Check the leveling signal input
points of the MCB.
4. Check whether the steel rope
slips.
