Speed command for speed operation can be input freely by using 3 methods:
① Using 3 digital speed commands ([Speed CMD1 (P3-01)] - [Speed CMD3 (P3-03)]
② Using external analog speed command
③ Based on override operation by combining methods of items ① and ②
The internal speed command selection effected based on these 3 methods is decided as
