motor rated slip x Pr.07-27 (Slip Compensation Gain) when the motor is at the rated load. If the
actual speed ratio is slower than expected, increase the parameter setting value; otherwise,
decrease the setting value.

Settings
 The Pr.07-29 to Pr.07-31 set the allowable slip level / time and the over-slip treatment when the
drive is running.
Motor Shock Compensation Factor

Settings
 If there are current wave motions in the motor in some specific area, setting this parameter can
effectively improve this situation
current wave motion occurs in low frequency and high-power, increase the value for Pr.07-32.)
Auto-restart Interval of Fault

Settings
 When a reset / restart occurs after a fault, the drive uses Pr.07-33 as a timer and starts counting
the numbers 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 Feedback Forward Gain

Settings
 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.
