6.8.2 Expanding Optical Servo Communication I/F
Usually, control unit OPT1 connector is used for optical servo communication I/F.
For expanding optical servo communication I/F, an expansion unit (FCU7-EX891) and an optical servo
communication I/F unit are required. Mount an expansion unit onto the right side of the control unit, and then
place an optical communication I/F unit into the expansion unit slot.
There are two types of optical servo communication I/F units available.
●
FCU7-HN551 (For 1ch expansion)
●
FCU7-HN552 (For 2ch expansion)
