DF24
151
Overtime at zero speed
The system has detected that
the elevator controller has
been given a zero-speed state
and exceeds the zero-speed
timeout time.
Drive controller keep too long time
under zero speed.
Check if inspection speed or rated
speed is reasonable.
DF25
152
Baseblock error
System detect baseblock
signal and cannot reset
error
1. Bad contact among chips on
mainboard;
2. Bad contact among main board
and power board.
1. Check the connection
between; Bad contact among
chips on mainboard;
2. Main board and power cable.
Replace main board.
DF26
153
Sequence of load
compensation is abnormal
When the load compensation
device starts, the system
detects the rotation of the
motor.
While drive controller operate load
compensation, the sequence is
abnormal.
Or brake open time is too short.
Check the brake and if Brake ON
Time setting is too short.
DF27
154
Angle tuning fail
Angle tuning with load not
completed.
Angle tuning fail with fault.
Solve angle tuning fault first, then
do it again.

without successful auto tuning, or
it will lose control.
DF28
155
Internal communication
error
The system has detected the
abnormal communication in
the main board.
1. Internal communication between
controllers is abnormal;
2. Component on mainboard is
abnormal;
3. Elevator controller gives wrong
commands.
1. Check if there is serious EMI or
contact with supplier;
2. Change the main board.
DF29
156
The running mode of
machine is abnormal
speed source selection F9-01
cannot match current logic.
Speed source selection F9-01 do not
adapt to current control logic.
When normal running, confirm
F9-01=2.
DF30
157
Power of bottom case
identification error
The main board cannot
correctly identify the bottom
case configuration
information.
1. Connection between main board
and power drive board is bad;
2. Component on mainboard is
abnormal;
3. Component on power drive board
is abnormal.
1. Check the connection
between main board and drive
power;
2. Change main board;
3. Change power board.
DF31
158
Communication error
between drive modules
Detection of communication
error between drive modules
Communication of internal drive chip is
abnormal.
1. Check if there is serious EMI or
contact with supplier;
2. Change main board.
DF32
159
Encoder Z (or R) signal is
abnormal
Motor has run for over 2
rounds but didn’t find Z
signal.
1. The controller finds
disconnection or interference in
Z pulse;
2. Component on mainboard is
abnormal;
3. Component on PG card is
abnormal.
Check if there is interference or
broken wire of Z pulse.
DF33
160
Before start, feedback speed
is abnormal.
Before elevator start, system
find the feedback speed is
over limit.
1. Encoder signal anomaly;
2. Brake force may be not enough or
already open.
1. Check A & B signals of
encoder;
2. Check brake.
DF34
161
While brake force detecting,
feedback movement of
encoder is too long.
1. Encoder feedback signal anomaly;
2. Brake force may be not enough or
already open.
Check the brake and encoder.
