Servo ON Function

This function brings the Inverter into speed servo lock status via an input terminal when "05" (sensor
vector control) is selected in V/f characteristics selection A044.
Allocate 54 (SON) to the desired multi-function input.
The Inverter does not accept the RUN command unless the SON terminal is turned on when SON
is allocated.
If the SON terminal is turned off during operation, the Inverter goes into free-run status. When the
SON terminal is turned on again, the Inverter restarts according to the setting of free-run stop se-
lection b088.
This function cannot be simultaneously used with the preliminary excitation function (55: FOC). If
FOC and SON are both allocated to multi-function input terminals, priority is given to FOC, and SON
is disabled.
