07-32
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.

07-33
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.
07-38
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.

07-62
dEb Gain (Kp)
Default: 8000
Settings 0–65535

07-63
dEb Gain (Ki)
Default: 150
Settings 0–65535
 Sets the PI gain of DC bus voltage controller when the dEb function activates.
 If the DC bus voltage drops too fast, or the speed oscillation occurs during deceleration after the
dEb function activates, adjust Pr.07-62 and Pr.07-63. Increase the Kp setting to quicken the control
response, but the oscillation may occur if the setting is too large. Use Ki parameter to decrease
the steady-state error to zero, and increase the setting to quicken the response speed.
