0: Disabled
1: Enabled
Normally, when using this servo amplifier in
the absolute value command method in the
incremental system, the home position will be
erased if the servo-on is turned off or switched
to the forced stop state. If this parameter is set
to "1", the home position will not be erased
even if the servo-on is turned off or switched
to the forced stop state. In this case, the
operation can be resumed by turning the
servo-on (SON) or canceling the forced stop
(EMG).

0: Disabled (Home position will be erased
when servo-on or EM2 is turned OFF.)
1: Enabled (Home position will not be erased
even when servo-on or EM2 is turned OFF,
or when an alarm that can be canceled by
resetting is generated. The operation can
be resumed.)
