 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.
