Chapter 12 Description of Parameter SettingsC2000
12.1-07-15
Motor Shock Compensation Factor
Default: 1000
Settings 0–10000
0: Disable
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
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 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
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.
dEb Gain (Kp)
Default: 8000
Settings 0–65535
dEb Gain (Ki)
Default: 150
Settings 0–65535
Sets the PI gain of DC BUS voltage controller when the dEb function activates.
If the DCBUS voltage drops too fast, or the speed vibration occurs during deceleration after the
dEb function activates, adjust Pr. 07-62 and Pr. 07-63. Increase the Kp setting to accelerate the
control response, but the vibration may occurs if the setting is too large. Use Ki parameter to
decrease the steady-state error to zero, increase the setting to accelerate the response speed.
