Deceleration
Jerk when
deceleration starts
Too fast deceleration at this section Increase F6-26, ranging 0 to 80%;
Or increase F0-18, ranging 0 to 20s
Vibration Overcurrent stall prevention occurs Make sure F3-18=170%
Jerk when
deceleration ends
Too fast deceleration at this section Increase F6-27, ranging 0 to 80%;
Or increase F0-18, ranging 0 to 20s
Creeping
speed
Vibration Torque output is insufficient Make sure F3-00=0, F3-01=0
Elevator gets
stuck
Torque output is insufficient Make sure F3-00=0, F3-01=0
Move much
slower than
expected
Torque output is insufficient Make sure F3-00=0, F3-01=0
Too small creeping speed setting Increase F4-16, ranging 0 to 100%;
Or decrease relevant multi-reference
Stop
Jerk Too fast deceleration at this section 1. Increase F6-27, ranging 0 to 80%;
Or increase F0-18, ranging 0 to 20s;
2. Use second deceleration time F8-04:
First, set F8-04 bigger than F0-18, ranging
F0-18 to 20s;
then set F8-26= creeping speed
Braking device applies too early Make sure F8-58=0.5Hz, then increase
F8-59,ranging 0 to 0.5s
Too strong DC injection at stop Decrease F6-13, ranging 0 to 100%
Slip Too short DC injection active time at stop Increase F6-14,ranging 0 to 1s
Too weak DC injection at stop Increase F6-13, ranging 0 to 100%
Braking device applies too late Make sure F8-58=0.5Hz, then decrease
F8-59, ranging 0 to 0.5s
Inaccurate
levelling position
Too slow deceleration 1. If F8-04 is not applied, then decrease F0-18,
ranging 0 to 20s;
2. If F8-04 is applied, then firstly decrease F8-04,
ranging F0-18 to 20s;
secondly set F8-26 = creeping speed
Slip occurs
Levelling varies
with different
loads
Too weak slip compensation For SVC, increase F2-06 or F 2-00;
For VF, increase F3-09
