Instructions Manual
(6) Step angle switch input(C.S)
① Operating current range : 4.0mA~5.3mA
The photo-coupler turns on with
inter-terminal voltage of 19.1 V~25.1 V.
(Photo-coupler diode V
F
≒ 1.1 V)
● Step angle division is switched to 1/20 divisions with the photo-coupler ON.
The setting for the STEP ANGLE SELECT switch is ignored.
●No displacement occurs even if the step angle is switched by the C.S signal.

● Switching the step angle by the C.S signal requires time "t1" and "t2" before
and after inputting drive pulse.
