DRIVER FAULT LIST (CONT'D)
Elevator over speed
The speed feedback
exceeds the speed
limit and last longer
than set time.
1. Max speed /last time set
incorrect;
2. Speed over-tuning;
3. Encoder feedback incorrect;
4. Wrong motor parameters setting.
1. Check speed limit setting;
2. Check the P/I parameter;
3. Check encoder;
4. Check motor parameters.
Speed over deviation
The speed deviation
exceeds the allowable
range(F9-03) and last
longer than set time.
1. System overload;
2. Accel/decel time short;
3. Parameter setting wrong;
4. Encoder cannot work properly;
5. Brake wrongly act;
6. Wrong allowable range set.
1. reduce system load;
2. Increase accel/decel time;
3. Check the parameters;
4. Check the encoder;
5. Exchange motor phase sequence or
exchange A+/A- and B+/B- wire;
6. Check brake action.
PG disconnect
Did not receive
encoder signal at
operation.
PG card type setting is
different with actual
one, system cannot
identify it.
1. Encoder wiring is broken, loosen
or wrong connection;
2. Encoder damaged;
3. Wrong PG type setting;
4. PG card damaged;
5. Brake not open.
1. check encoder wiring;
2. Check encoder;
3. Check if F8-02 PG type is same
with actual PG card;
4. Check connection between PG
card and main board;
5. Check if brake can open;
6. If software version is old, please
enter Fault report->Controller Fault, and
find E2, E3 value:
Incremental encoder:
(1)E3=35, no speed feedback;
(2)E2=16, U/V/W signals error;
Sin/Cos encoder:
(1)E3=35, no speed feedback;
(2)E3=29,31,36, abnormal
communication between main board
and SPG card;
(3)E3=28 or 34, C/D signal error;
(4)E3=32 or 33, A/B/C/D signals are
highly similar;
7. If software version is new, these
errors are DF18, DF19 and DF20.
Data fault at saving parameters.
Baseblock circuit error
When system find
baseblock valid and
receive running
command, but running
condition isn’t ready.
1. Wiring for baseblock at X14 is
incorrect;
2. Setting electric level for
baseblock at X14 is incorrect.
1. Check the wiring at X14;
2. Modify the parameters.
Motor overload
current output exceed
150% (200%) rated
value for 60s (10s).
Motor current exceed
150% (200%) rated
value for 60s (10s).
1. System load too heavy;
2. System power rating too low;
3. Low capacity controller.
1. Reduce system load;
2. Change a more suitable controller;
3. Change motor or increase F5-08
rated current properly to promote
overload capacity.
MC contactor bad
action
Controller main
contactor MC does not
close after given close
command for set time.
1. Wrong wiring for MC contactor;
2. MC contactor damaged;
3. Wrong FX-23 surge feedback
type setting;
4. Drive power on power board is
abnormal.
1. Try to reset the power, if this error
come again, contact supplier for
replacement;
2. Change FX-23 status, then power
off and power on again.
