(3) When the target position is reached, press the Enter key on the Digital Operator. Press the key
on the data display screen (the PRG LED indicator is lit).
(4) The current position is set to the area corresponding to the position command source set in
teaching selection P074.
(However, the P074 setting is not stored. After the power is shut off or after reset, this parameter
is indicated as “00” (x00).)
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 will 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 inputs, priority is given to FOC, and SON is dis-
abled.
