ASDA-B3 Wiring 3.3.2 Signal explanation for CN1 I/O connector (for M, F, and E models) The following table details the signals listed in the previous section. 3 General signals: Note: the pulse input function is supported by the B3A series only. 3-35 Wiring method Signal Pin No. Description (refer to Section 3.3.7) Analog command (input) V REF _ 19 (1) When the motor speed command is set to -10V to +10V, it means the rotation speed is -3000 to +3000 rpm (default). You can set the corresponding range with parameters. (2) When the motor position command is set to -10V to +10V, it means the range of the rotation position is -3 to +3 cycles (default).
C1 T REF _ 20 When the motor torque command is set to -10V to +10V, it means the rated torque is -100% to +100%. C1 Analog monitor (output) MON1 MON2 21 22 The operation status of motor, such as speed and current, can be displayed in analog voltage. This servo drive provides 2 output channels. You can select the data to be monitored with P0.003. This signal is based on the power ground. C2 Position pulse* (input) PULSE+ PULSE- 25 26 Position pulse can be sent by the line driver (single-phase max. frequency 4 MHz) or open collector (single-phase max. frequency 200 kHz). Three command types can be selected with P1.000, CW/CCW pulse, pulse and direction, and A/B pulse.
If open collector type is used when sending position pulses, CN1 should be connected to an external power supply for pull high. C3/C4 SIGN+ SIGN- 23 24 PULL HI P _ PULL HI S _ 14 13 Position pulse (output) OA /OA 1 2 Encoder signal A, B, and Z output (line driver). C9/C10 OB /OB 11 12 OZ /OZ 3 4 Power COM+ 5 NPN: COM+ is for DI voltage input and requires an external power supply (24V ± 10%). PNP: COM+ is for DI voltage input (negative end) and requires an external power supply (24V ± 10%). - GND 10 GND for analog signal and differential output signal.
