Wiring ASDA-B3 3.3.5 Signal explanation for CN1 I/O connector (for L model) The following table details the signals listed in the previous section. 3 General signals: Note: the analog voltage control function is not supported by the B3B series. 3-40 Wiring method Signal Pin No. Description (refer to Section 3.3.7) Analog command (input) V REF _ 20 (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 _ 18 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 17 14 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- 43 41 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- 39 37 PULL HI P _ PULL HI S _ 36 35 Position pulse (output) OA /OA 21 22 Encoder signal A, B, and Z output (line driver). C9/C10 OB /OB 25 23 OZ /OZ 13 24 OCZ 44 Encoder Z pulse output (open collector). C11 Power COM+ 11 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 19, 29, 40 GND for analog signal and differential output signal. Other NC 38, 42 No connection. This is for internal use only.
Do not connect to NC, or it may damage the servo drive.
