Wiring ASDA-B3 C3-2: the source for the pulse input is open collector PNP type equipment, which uses the external power supply. 3 Servo drive Controller DC 24V + - 35 PULL HI_S 1.5 k Ω Max. pulse input frequency: 200 Kpps 51 Ω 37 SIGN- 51 Ω 36 PULL HI_P 1.5 k Ω Max. pulse input frequency: 200 Kpps 51 Ω 41 PULSE- 51 Ω SG Note: 1. This is supported by the B3-L model and the B3A series only. 2. The pin definition of the communication type models is different from that of the L model. Communication type model pins: PULL HI_S (13), PULL HI_P (14), SIGN- (24), and PULSE- (26). 3-50
