Fault code
Fault type
Possible cause
Action to take
E025 PG
error
1) PG signal cable broken
2) PG signal reverse-connected
3) Output cable connection error or
disconnected (synchronous motor)
1) Rectify the PG connection
2) Change the setting of F4.02 (PG reversed) or change
the connection of any two phases of the motor
3) Check the output cable connection (synchronous
motor)
E026 Overspeed
error
1) Output cable phase failure
2) Initial angle of synchronous motor error
1) Check that the output cable is not disconnected
2) Check that the initial angle of the synchronous motor is
correct through tuning
E027 Reserved
E028
Parameter setting
error
1) OD width auto-learning is not set as keypad
control mode or terminal control mode
2) General keypad operation mode is not used
in motor tuning process
3) CD and OD time is set shorter than all the
settings of CD and OD time
4) In the dual motors control mode, tuning is
conducted or synchronous motor is used
5) F5.00 (X1 terminal) is not set as zero (0)
when the load is a synchronous motor, and
incremental PG is used
1) Set F0.02=1 or F0.02=2 in OD width auto-learning
2) Set F002 to 0 in motor tuning
3) Set the OD and CD time to a bigger value and ensure
the setting of F006 is bigger than the sum of all the
settings of CD and OD time
4) The tuning can be conducted only in the single motor
mode (F4.11 = 0), and only one motor can be connected.
Besides, the synchronous motor can only be used in the
single motor mode (F4.11 = 0).
5) F5.00 (X1 terminal) must be set as zero (0) when the
load is a synchronous motor, and incremental PG is used
E029
Door width
auto-learning error
1) The OD width obtained from the
auto-learning process is 0.
2) The OD width obtained from the
auto-learning process is out of the limits
3) Door width auto-learning overtime
1) Check the PG wiring and relevant parameters
2) Check the mechanical system of the elevator door
E030
OD overtime error
1) The motor running direction is reverse to the
definition of OD
2) OD contacts error or setting error
3) PG cable is broken
1) Change the phase rotation of the motor or set F0.03 to
1
2) Check OD contacts signal
3) Check PG cable
4) Check the mechanical system of elevator door
E031
CD overtime error
1) The motor running direction is reverse to the
definition of CD
2) CD contacts error or setting error
3) PG cable is broken
1) Change the phase rotation of motor or set F0.03 to 1
2) Check CD contacts signal
3) Check PG cable
