3) Auto sequence operation
If I/O-50 [Auto (Sequence) Operation selection] is set to 1 {Auto-A} or 2 {Auto-B}, up to 5 sequences can be set with max of
8 steps (speed) in each sequence. Therefore, max 40 operating steps can be made. Two different types of auto sequence
(A, B) operation are available.
