When sensorless vector control, 0Hz sensorless vector control, or vector control with sensor is
selected for the control method, the Control Gain Switching function selects between two sets
of gains in the internal speed loop. These gains are used in proportional and integral compensa-
tion. Use option code 26 to assign the [CAS] function to an intelligent input terminal. Use
option code 43 to select between P and PI control.
