GD-5510-01
Instructions Manual
(6) Step angle switch input(C.S)
① Operating current range : 2.6mA~19.5mA
The photo-coupler turns on with
inter-terminal voltage of 4.5 V~26.4 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.
