Fault
Code
Name Possible Causes Solution Level
Err31
Emergency
running
abnormal
1: Overspeed occurs
during inspection or
shaft auto-tuning.
2: The running speed
exceeds 1.15 times of
the maximum speed
(F0-03).
3: The speeds during
shorting motor stator
braking mode and
emergency running
exceed 1/2 of the rated
speed.
1: Decrease the inspection speed or
perform motor auto-tuning again.
2:
•
Check that the encoder is normal.
•
Set the motor nameplate
parameters correctly
•
Perform motor auto-tuning again.
3:
•
Check that the shorting PMSM
stator contactor function is
enabled.
•
Check that the EPS capacity is
proper.
•
Check that the emergency running
speed is set properly.
Err33
Elevator speed
abnormal
101: The detected
running speed during
normal-speed running
exceeds the limit.
102: The speed
exceeds the limit during
inspection or shaft auto-
tuning.
103: The speed exceeds
the limit in shorting
stator braking mode.
104: The speed
exceeds the limit during
emergency running.
105: The emergency
running time protection
function is enabled (set
in Bit8 of F6-45), and the
running time exceeds
50s, causing the timeout
fault.
101:
•
Check whether the encoder is
used properly.
•
Check the setting of motor
nameplate parameters. Perform
motor auto-tuning again.
102: Attempt to decrease the
inspection speed or perform motor
auto-tuning again.
103: Check whether the shorting
PMSM stator function is enabled.
104, 105:
•
Check whether the emergency
power capacity meets the
requirements.
•
Check whether the emergency
running speed is set properly.
