4.3.20 Servo-on function

The servo-on function allows you to set the inverter in a speed-servo locking state with a signal input via an input terminal during operation. This function is effective when "05" (vector control with sensor) is specified as the V/F characteristic curve selection (A044).

To use this function, assign function "54" (SON) to an intelligent input terminal.

After the SON function has been assigned, the inverter accepts an operation command only when the SON terminal is on.

If the SON terminal is turned off while the inverter is operating the motor, the inverter sets the motor into the free-running state. If the SON terminal is subsequently turned on, the inverter restarts the motor according to the setting of the festart mode after FRS (b088).

This function cannot be used together with the forcing function (55: FOC). If both the FOC and SON functions are assigned to different intelligent input terminals, the FOC function has priority over the SON function (the SON function cannot be used).
