ADLINK DIN-814P-A4 Panasonic servo adapter board configuration

In the field of industrial automation motion control, efficiently integrating high-performance motion control cards with Panasonic series AC servo drives is a key link in system integration. The DIN-814P-A4 launched by ADLINK is a 4-axis interface adapter board designed specifically for Panasonic's MINAS A4/A5 series 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-814P-A4 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 that is compatible with Panasonic MINAS A4/A5 series servo drives (such as MADHT, MBDHT, etc.), 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+5V 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), and reset RES. Simultaneously provide BH # auxiliary interface (6-pin) for expanding Panasonic's defined key signals (such as brake control, Z-phase output, speed/torque monitoring, etc.). The board is powered by an external+24VDC power supply (CN1) to provide energy to all isolated side circuits.

Pulse speed selection jumper (JP1~JP4): Each axis corresponds to a jumper used to match the upper limit of the pulse input frequency of Panasonic servo drives:

1-3 and 2-4 short circuit: Choose 500kpps (500kHz) mode, suitable for lower pulse frequency applications.

Short circuiting 3-5 and 4-6: Select 2Mpps (2MHz) mode, suitable for high-speed and high-precision positioning requirements.

Be sure to set the correct settings based on the driver parameters and the maximum output frequency of the motion card, otherwise it may result in pulse loss or inability to respond.

Interface Definition and Signal Explanation

1. CNIF # Panasonic servo interface (50 pin)

This is the core interface of DIN-814P-A4, used to connect Panasonic MINAS A4/A5 series servo drives. Analyze key signals by functional grouping as follows:

Pulse/direction command (differential, 500k/2M optional)

Explanation of Pin Signal Direction

3 OUT-500K output 500k mode pulse negative terminal

4 OUT+500K output 500k mode pulse positive terminal

5 DIR-500K output 500k mode direction negative terminal

6 DIR+500K output 500k mode direction positive terminal

44 OUT-2M output 2M mode pulse negative terminal

45 OUT+2M output 2M mode pulse positive terminal

46 DIR-2M output 2M mode direction negative terminal

47 DIR+2M output 2M mode direction positive terminal

Important: According to the JP jumper selection, the actual effective pulse/direction pin groups are different. The 500k mode uses pins 3-6, while the 2M mode uses pins 44-47. The two modes cannot be used simultaneously.

Operation pulse signal (single ended, used for special mode)

Explanation of Pin Signal Direction

1 OPC1 input/output operation pulse signal negative terminal (open collector)

2 OPC2 input/output operation pulse signal positive terminal (open collector)

These two pins are usually used for the pulse input mode built into Panasonic drivers (such as long line drive or open collector), but they may not be used in differential mode.

Encoder feedback (differential input)

Explanation of Pin Signal Direction

21 EA+input encoder A-phase positive terminal

22 EA - Input encoder A negative terminal

48 EB+input encoder B-phase positive terminal

49 EB Input Encoder B Negative Terminal

23 EZ+input encoder Z-phase positive terminal

24 EZ - Input encoder Z-phase negative terminal

Control and status signals

Explanation of Pin Signal Direction

29 SVON input servo enable (Servo On, from motion card)

30 ERC input deviation counter cleared (from motion card)

31 RES input reset signal (from motion card)

32 C-Mode input control mode selection (switching position/speed/torque)

28 DIV input electronic gear selection (switching frequency division ratio)

27 TL-SEL input torque limit selection

26 VS-SEL input speed selection

10 BRK-OFF - output electromagnetic brake negative terminal (control holding brake)

11 BRK-OFF+output electromagnetic brake positive terminal

12 ZSP outputs zero speed signal (valid at zero speed)
