Input signal

Servo-on [S-ON]: Sequence input signal (Reference value 1)

The signal makes the servomotor ready to rotate.
 Function
The servomotor is ready to rotate while the servo-on [S-ON] signal remains turned on.
When the servo-on signal is turned off, the gate for IGBT is turned off and the servomotor does
not rotate. At this time, the servomotor in free-run and all rotation commands are ignored.
If the signal is turned off during rotation, controlled stop is caused according to the setting of
PA2_61 (action sequence at servo-on OFF). The stopping profile follows the setting of PA2_61
(action sequence at servo-on OFF), too.
If there is no alarm, activation of servo-on [S-ON] and forced stop [EMG] arranges the state ready
to rotate.
 Parameter setting
To assign the servo-on [S-ON] signal to a sequence input terminal, specify the corresponding
value ("1") to the input terminal function setting parameter.
