3. The current keeps large during
low speed running.
normal.
4. Check whether the encoder is
stuck mechanically during
running.
5. Check whether the brake keeps
released during running.
Synchronous
encoder
wiring fault
Error occurs to the wiring of
synchronous encoder
Levelling
signal
abnormal
Levelling or door zone signal is
stuck or breaks.
1. Check whether the levelling
and door zone sensors work
properly.
2. Check the installation
verticality and depth of the
levelling flags.
3. Check the input points of the
MCB.
Short circuit
fault to ground
The output is short circuited to
ground.
Check the power cable or contact
Monarch.
Contact the agent or Monarch.
PMSM
U,V,W jump
out contactor
feedback
abnormity
The shorting PMSM stator's
output is inconsistent with the
feedback.
1. Check whether the feedback
contact (NO, NC) of the contactor
is consistent with the parameter
setting of the MCB.
2. Check whether the state of the
MCB output indicator is
consistent with the contactor
action.
3. Check whether corresponding
feedback contact acts after the
contactor acts, and whether the
corresponding feedback input
point of the MCB acts correctly.
4. Check whether the shorting
PMSM stator contactor is
consistent with the MCB output
feature.
5. Check the coil circuit of the
shorting PMSM stator contactor.
Elevator
position
abnormity
1. The controller does not receive
levelling signal within the time
set in F9-02.
2. The up and down limit
switches are met during the re-
levelling process.
3. The levelling signal is not
received when re-levelling times
out.
1. Check whether the levelling
sensor mal-acts in non-levelling
zone.
2. Check whether the levelling
signal cables are connected
reliably and whether the signal
copper wires may touch the
ground or be short circuited with
other signal cables.
3. Check whether the encoder is
used properly.
