(6) Step Angle Switch Input（C.s - Melec GDB-5311A-00 Instruction 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
● 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.
