available operation mode is End operation, Keep operation, Continuous operation.
(b) Position setting range is –2147483648
∼ 2147483647 Pu
lse.
(c) As the operation is different according to Position Override command during operation, cares should be taken in using.
In other words, if position of position override at the moment of commanding position override is bigger than the position it
stopped at, the positioning direction would be forward. If it is smaller, the direction would be reverse.
