
The Source of External Pulse:
0: Low-speed optical coupler (CN1 Pin: PULSE, SIGN)
1: High-speed differential (CN1 Pin: HPULSE, HSIGN)
Position pulse can be input from these terminals, /PULSE (43), PULSE (41), HPULSE (38), /HPULSE (36),
/SIGN (39), SIGN (37) and HSIGN (42), /HSIGN (40). It can be an open-collector circuit or line driver.
Please refer to Chapter 3.10.1 for wiring method.
