GD-5410v1
Instructions Manual
(6) Step angle switch input（C.S）
① Operating current range : 2.6mA～19.5mA
The photo-coupler turns on with
GD-5410v1
inter-terminal voltage of 4.5V～26.4V.
(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.
