Chapter 12 Description of Parameter SettingsC2000-HS
12.1-07-15
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.
