ratio is slower than expected, increase the parameter setting value; otherwise, decrease the
setting value.
Default: 0
Settings 0.0–100.0%
0: No detection
Slip Deviation Detection Time
Default: 1.0
Settings 0.0–10.0 sec.
Default: 0
Settings 0: Warn and continue operation
1: Fault and ramp to stop
2: Fault and coast to stop
3: No warning
Parameters Pr.07-29–Pr.07-31 set the allowable slip level / time and the over-slip action when the
drive is running.
Motor Shock Compensation Factor
Default: 1000
Settings
0–10000
If there are current wave motions in the motor in some specific area, setting this parameter can
effectively improve this situation.
When the current wave motion occurs in low frequency and high-power, increase the value for
Pr.07-32.
Auto-restart Interval of Fault
Default: 60.0
Settings 0.0–6000.0 sec.
When a reset/restart occurs after a fault, the drive uses Pr.07-33 as a timer and starts counting
the number of faults within this time period. Within this period, if the number of faults does not
exceed the setting for Pr.07-11, the counting clears and starts from 0 when the next fault occurs.
PMSVC Voltage Feed Forward Gain
Default: 1.00
Settings 0.50–2.00
Adjusts the PMSVC voltage feedback forward gain, and to meet the demand of rapid feedback
application.
Pr.07-38 = 1.00 means forward feedback = Ke × motor rotor speed
Refer to Section 12-2 “PMSVC adjustment” for details.
