Stage Symptom Diagnostics Remedies
Start
Rollback
The start frequency is too low
.
Increase F6-03, ranging from 0 to10 Hz
The output torque is insufcient
.
Make sure F3-00 = 0, F3-01 = 0
Starting jerk The start frequency is too high
.
Decrease F6-03, ranging from 0 to 10 Hz
Acceleration
Jerk when
acceleration starts
The acceleration is too fast at this
section
.
Increase F6-08, ranging from 0 to (100-(F6-09))%
Or increase F0-17, ranging from 0 to 6500s
Jerk when
acceleration end
The acceleration is too fast at this
section
.
Increase F6-09, ranging from 0 to (100-(F6-08))%
Or increase F0-17, ranging from 0 to 6500s
Vibration
The overcurrent stall prevention
occurs
.
The drive current reaches the limit
.
Nominal speed Vibration The current loop PI gain is too big
.
Double check the motor parameters and then perform
motor auto-tuning once more
Deceleration Vibration
The overcurrent stall prevention
occurs
.
It reaches the current limit
.
Stop
Jerk The DC injection is too strong at stop
.
Decrease F6-13, ranging from 0 to 100%
.
Slip
The DC injection active time is too
short at stop
.
Increase F6-14, ranging from 0 to 100s
.
The DC injection is too weak at stop
.
Increase F6-13, ranging from 0 to 100%
.
The braking device applies too late
.
Check the timing of braking device
.
