Motor 1 (A)), the drive compensates the frequency with this parameter.
 This parameter is set to 1.00 automatically when Pr.00-11 (Speed Control Method) is changed
from V/F mode to vector mode. Apply the slip compensation after load and acceleration. Increase
the compensation value from small to large gradually; add the output frequency with motor rated
slip * 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.

 Pr. 07-29 to Pr. 07-31 set the allowable slip level / time and the over-slip action 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. When running with high frequency or PG, set this parameter to 0.
When the 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.
