ASDA-B3 Wiring Pin assignment: 3 Note: 1. NC represents “No connection”, which is for internal use only. Do not connect to NC, or it may damage the servo drive. 2. The analog voltage control function is not supported by the B3B series. 3. Do not directly input the 24V power supply to the SIGN+, SIGN-, PULSE+, and PULSE- pins, or the circuit elements will be damaged.
