DF14
BR
Brake unit fault
While system find DC bus
voltage reach braking
range, but braking tube
keep open and last over
preset time.
1. defective brake cable or damaged
brake elements or IGBT module;
2. External brake resistor disconnected
or not connected;
3. Bad connection between the main
board and the power board.
1. Check brake resistor;
2. Replace the controller;
3. Check the main board and the
power board connector.
DF15
OF
Output phase lost
System find phase lost or
break, running condition is
not ready
1. Output cable break or loose
terminal;
2. Motor stator cable disconnected.
1. Check output cable/terminal;
2. Check motor stator cable;
3. Set FD-21. BIT2 to 1 to disable
this detection.
DF16
SCF
Output current remains at
elevator stop
After the system executes
the stop instruction, the
output current is not zero
and the preset time is kept.
1. Controller damaged;
2. Cabinet works abnormally.
1. Change the controller;
2. Check cabinet wiring.
DF17
SRF
Elevator slips after stop
After the system executes
the stop command, the
encoder's feedback speed is
not zero.
1. Brake/encoder loose;
2. Encoder interference.
1. Fasten brake/encoder;
2. Remove interference source.
DF18
UF
Incremental:
Signal U of encoder wire
lost
Sin/Cos:
Signal C and D abnormal
1. Encoder damaged or wiring
incorrect;
2. Wrong PG type setting.
1. Check encoder and wirings;
2. Correct PG type setting.
DF19
VF
Incremental:
Signal V of encoder lost
Sin/Cos:
A, B, C, D signals are highly
similar
1. Encoder damaged or wiring
incorrect;
2. Wrong PG type setting.
1. Check encoder and wirings;
2. Correct PG type setting.
DF20
WF
Incremental:
Signal W of encoder wire
lost
Sin/Cos:
Abnormal communication
between SPG card and
main board
1. Encoder damaged or wiring
incorrect;
2. Wrong PG type setting;
3. Bad connection between the main
board and the PG card.
1. Check encoder and wirings;
2. Correct PG type setting;
3. Check whether the PG card is
fastened to the main board.
DF21
DF
Parameter setting error
System find rated
current/no-load current/
rated slip/ poles/pulse
setting error.
Parameter setting error
Check rated current/no-load current/
rated slip/ poles/pulse setting.
Check parameter setting.
DF22
SDF
Internal programmer
self-check error
The system detected the
types of faults that cannot
be classified into routine
fault types.
Internal data setting error.
Please contact with supplier.
DF23
150
Current collection sensor
error
When the elevator starts,
the system detected that
the instantaneous current
value of the current sensor
is not near the zero point.
1. Bad contact between main board
and drive power;
2. Hardware error.
1. Please with contact supplier;
2. Check the main board and
driver power board
connection.
