PARAMETERS
364
A522

Encoder stop check time
0.5 s 0 to 5 s
If the orientation complete signal (ORA) has never been output
and the encoder stays stopped for the set time without completing
orientation, the orientation fault signal (ORM) is output. If the ORA
signal has been output before but the orientation cannot be
completed within the set time, the ORM signal is also output.
365
A523

Orientation limit
9999
0 to 60 s
The time elapses after passing the creep switchover position is
measured. If orientation cannot be completed within the set time,
the orientation fault signal (ORM) is output.
9999 Set to 120 s.
366
A524

Recheck time
9999
0 to 5 s
When the start signal is turned OFF with the orientation command
(X22) ON after stopping the motor by orientation control, the
present position is checked again after the set time elapses, and
the orientation complete signal (ORA) or orientation fault signal
(ORM) is output.
9999 Not checked.
