• When sending references from the host controller to the SERVOPACK, P control mode can be selected from the host
controller for particular operating conditions. This mode switching method can be used to suppress overshooting and
shorten the settling time. Refer to 9.4.5 Using the Mode Switch (P/PI Switching) for more details on inputting the /P-
CON signal and switching the control mode for particular operating conditions.
• If PI control mode is being used and the speed reference has a reference offset, the servomotor may rotate very slowly
and fail to stop even if 0 is specified as the speed reference. In this case, use P control mode to stop the servomotor.
