ADLINK DIN-814M-J3A Mitsubishi servo adapter board configuration

When combined with PCI-8164/PXI-8164/MPC-8164, the PSD of axis 0/1 is mapped to CMP1/2 (compare output), and the PSD of axis 3/4 is mapped to LTC3/4 (latch input). Please refer to the corresponding sports card manual for specific functions.

3. SJ # stepper interface (10 pins)

Used for stepper motor drivers or other brands of servos (pulse direction mode):

1+24V power isolation+24V output

2 EX-EMG input external emergency stop (parallel with IOIF)

3 PEL input positive limit

4 MEL input negative limit

5 PSD input forward deceleration

6 MSD input negative deceleration

7 ORG input origin

8 RES input reset

9 EXGND external ground

Attention: The EX-EMG, limit and other signals of SJ are directly connected to the corresponding pins of IOIF internally, only with different wiring positions.

4. BH # auxiliary interface (10 pins)

Provide additional signals for users to directly connect critical signals without using the CNIF main cable:

5. CN1 external power supply and emergency stop input (2-pin)

1 EXGND external power ground

2 EX+24V external+24V power input (DC 24V ± 5%)

This power supply supplies power to all isolated side circuits, and it is recommended to provide a current of 1A or above.

6. Jumper J1~J4 (EMG signal source selection)

Each axis corresponds to a jumper (J1~J4) used to select the source of the emergency stop signal:

Jumper position function

1-2 Short circuit EMG signal directly connected to EXGND (i.e. internal forced emergency stop), external EX-EMG invalid (normally closed mode)

2-3 Short circuit EX-EMG (from IOIF or SJ) to the driver EMG pin, external emergency stop switch is active

Default: The factory setting is usually set to 1-2 short circuits (external emergency stop disabled). If an external emergency stop button is required, the jumper must be changed to a 2-3 short circuit, and the emergency stop switch must be connected in series between EX-EMG and EXGND (normally closed contact, disconnected or short circuited when pressed? The manual states "While EX-EMG and EXGND are open, the motor will not move." This means that the motor stops when EX-EMG and EXGND are disconnected, so the emergency stop button should be normally closed, triggering an emergency stop when disconnected).

Typical wiring guidance

1. Mitsubishi J3A servo drive connection

Use the 50 pin 1:1 dedicated cable provided by ADLINK (one end connected to CNIF # and the other end connected to driver CN1A or CN1B). If self-made, it is necessary to strictly follow the pin definitions for corresponding connections.

Connect the CN2 (100 pin SCSI) of the motion control card to the CN1 (or onboard backup CN1) of DIN-814M-J3A via a flat cable.

Set the J1~J4 jumper according to whether an external emergency stop is used (2-3 short circuits are recommended).

Connect the external+24V power supply to CN1.

Connect sensors such as limit and origin to the corresponding terminals of IOIF #, paying attention to the sensor type (NPN/PNP) that matches the input characteristics of the board (input is low level valid, i.e. EXGND triggered).

Before powering on, check all wiring and confirm that there are no errors before powering on.

2. Connection of stepper motor driver

Connect the pulse+, pulse -, direction+, and direction - of the stepper driver to the OUT+, OUT -, DIR+, and DIR - of SJ #, respectively.

If the driver requires an enable signal, connect SVON; If alarm input is required, connect to ALM (but SJ does not have ALM and requires BH or CNIF extension).

Use+24V to power the driver optocoupler (if needed).

Attention: SJ is connected in parallel with CNIF signal, and CNIF must be left vacant.

3. Wiring of limit, origin, and deceleration sensors

Connect PEL, MEL, ORG, PSD, MSD to the output terminals of the corresponding proximity switch or micro switch, and connect the other end of the switch to EXGND or+24V, depending on the sensor type (NPN low effective or PNP high effective). The input of the board is optocoupler isolated and triggered at a low level (short circuit to EXGND), so it is recommended to use NPN type sensors.

If a normally closed limit is used, it is normally at a high level (through a pull-up resistor) and pulled low when triggered.

4. External emergency stop circuit

Connect one end of the external emergency stop button (normally closed contact) to EX-EMG of IOIF # and the other end to EXGND.

Ensure that the J1~J4 jumper is placed in a 2-3 short circuit.

During normal operation, EX-EMG and EXGND are conductive (low level). When the emergency stop button is pressed, the contact opens and EX-EMG remains suspended (high level). The driver receives the EMG signal and stops.

5. Analog command (speed/torque)

If speed or torque control mode is required, the D/A output of the motion card can be connected to the VLA (speed limit) or TC (torque command) pin, and the driver parameters need to be configured for analog command mode.
