Fault Code Name Possible Causes Solution Level
Err51
CAN
communication
abnormal
Subcode 101:
Feedback data
of CANbus
communication with
the CTB remains
incorrect.
• Check the communication cable connection.
• Check the power supply of the CTB.
• Check whether the 24 V power supply of the
controller is normal.
• Check whether there is strong-power
interference on communication.
1A
Err52
HCB
communication
abnormal
Subcode 101:
Feedback data
of Modbus
communication with
the HCB remains
incorrect.
• Check the communication cable connection.
• Check whether the 24 V power supply of the
controller is normal.
• Check whether the HCB addresses are
repeated.
• Check whether there is strong-power
interference on communication.
1A
Err53
Door lock fault
Subcode 101: The
door lock feedback
signal remains active
3s after door open
output.
• Check whether the door lock circuit is
normal.
• Check whether the door lock feedback is
correct.
5A
Subcode 102: The
states of the door
lock multi-way
feedback contacts are
inconsistent, or the
states of door lock 1
and door lock 2 are
inconsistent.
Subcode 105: Door
lock 1 shorting signal
is active upon shorting
door lock circuit relay
output 3s after door
open.
Subcode 106: Door
lock 2 shorting signal
is active upon shorting
door lock circuit relay
output 3s after door
open.
Subcode 104: The
higher-voltage and
low-voltage door
lock signals are
inconsistent.
When the higher-voltage and low-voltage door
lock signals are detected at the same time, the
time when the MCB receives the two signals
has a deviation of above 1.5s.
This subcode is reset at power-off and power-
on again.
Subcode 107: The
door lock shorting
input is selected
but the feedback
signal remains off or
disconnected.
Check whether the signal cable of door lock
shorting feedback is not connected or breaks.
Err54
Overcurrent
at inspection
startup
Subcode 102: The
current at startup for
inspection exceeds
120% of the rated
current.
• Reduce the load.
• Check whether the motor phase sequence is
correct.
• Change FC-00 Bit1 to 1 to cancel the startup
current detection function.
