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

ADLINK DIN-814M-J3A adapter board application and configuration detailed explanation

In the field of industrial automation motion control, efficiently integrating high-performance motion control cards with specific brand servo drives is a key link in system integration. The DIN-814M-J3A launched by ADLINK is a 4-axis interface adapter board designed specifically for Mitsubishi J3A series AC servo drives. It is also compatible with stepper motor drivers and provides standardized signal routing solutions for motion control cards such as PCI-8134, PCI-8164, PXI-8164, and MPC-8164. This article will provide you with a complete technical guide from the dimensions of hardware architecture, interface definition, jumper configuration, typical applications, and troubleshooting.

Product positioning and hardware overview

DIN-814M-J3A is a passive adapter board (passive backplane), whose core function is to convert the 100 pin SCSI main interface (CN1/CN2) of the motion control card into industrial terminals for easy on-site wiring. It supports up to 4 motion axes, each axis providing two interface options:

CNIF # (# represents axis numbers 1-4): a 50 pin dedicated interface, compatible with Mitsubishi J3A series servo drives (such as MR-J3A-A/B models), including complete instructions, feedback, control, and status signals.

SJ #: A 10 pin simple interface used to connect stepper motor drivers or other drivers that support pulse+direction input, including pulse, direction, enable, alarm, and power output.

Important warning: CNIF # and SJ # on the same axis are directly short circuited (signal parallel) inside the PCB. It is strictly prohibited to use two interfaces at the same time, otherwise it may cause signal conflicts and hardware damage.

In addition, each axis is equipped with an IOIF # (9-pin mechanical I/O interface) for connecting limit switches (PEL/MEL), origin signal ORG, deceleration signal (PSD/MSD), reset RES, and external emergency stop EX-EMG. Simultaneously provide BH # auxiliary interface (10 pins) for expanding other signals defined by Mitsubishi J3A, such as speed/torque command, speed arrival, zero speed, torque limit, etc. The board is powered by an external+24VDC power supply (CN1) to provide energy to all isolated side circuits.

Interface Definition and Signal Explanation

1. CNIF # Mitsubishi J3A servo interface (50 pins)

This is the core interface of DIN-814M-J3A, used to connect Mitsubishi J3A series servo drives. Analyze key signals by functional grouping as follows:

Pulse/Direction Command (Differential)

Explanation of Pin Signal Direction

10 OUT+output pulse signal positive terminal

11 OUT - Output pulse signal negative terminal

35 DIR+output direction signal positive terminal

36 DIR - Negative terminal of output direction signal

Encoder feedback (differential input)

Explanation of Pin Signal Direction

4 EA+input encoder A-phase positive terminal

5 EA - Input encoder A negative terminal

6 EB+input encoder B-phase positive terminal

7 EB Input Encoder B Negative Terminal

8 EZ+input encoder Z-phase positive terminal

9 EZ - Input encoder Z-negative terminal

Control and status signals

Explanation of Pin Signal Direction

15 SVON output servo enable (Servo On)

16 SP2 output speed selection 2 (for multi speed switching)

17 ABSM outputs forward rotation command (for absolute value system)

18 ABSR outputs reverse rotation command

41 ERC output deviation counter cleared

42 EMG output emergency stop (to driver)

45 LOP output control selection (switching control mode)

19 RES input reset signal (from external)

22 ABSB0 input speed arrival signal

23 ZSP input zero speed signal

24 INP input positioning completion signal

25 TLC input limit torque signal

48 ALM input servo alarm

49 RDY input servo ready

2 VLA output simulation speed limit (0~± 10V)

27 TC output analog torque command (0~± 10V)

1 P15R output+15V power supply (for external circuit power supply)

20,21+24V output isolation+24V output (provided by external power supply)

Special note:

ABSM/ABSR/ABSB0 is a signal used by Mitsubishi J3A for absolute value encoder communication and status feedback, and non absolute value mode is not necessary.

SP2, when combined with other speed selection pins, can achieve multi-stage speed control. Please refer to the Mitsubishi manual for details.

VLA/TC is an analog command that can be used for speed/torque control mode, but attention should be paid to the corresponding parameter settings of the driver.

2. IOIF # Mechanical I/O Interface (9-pin)

9-pin connectors corresponding to each axis, used to connect limit, origin, deceleration, and emergency stop signals:

Explanation of Pin Signal Direction

1+24V power supply external+24V (for sensor power supply)

2 EX-EMG input external emergency stop signal (low level valid)

3 PEL input positive direction limit

4 MEL input negative direction limit

5 PSD input forward deceleration signal

6 MSD input negative deceleration signal

7 ORG input origin signal

8 RES input reset signal

9 EXGND external ground (shared with other pins of IOIF)

Differences in PSD signal function (related to sports card models):

When combined with PCI-8134, PSD serves as a forward deceleration signal (Slow Down).
