Application and Configuration of ADLINK DIN-814Y Adapter Board

ADLINK DIN-814Y adapter board application and configuration detailed explanation

In industrial automation motion control systems, reliable connection between high-performance motion control cards (such as ADLINK's PCI-8134, PCI-8164, PXI-8164, or MPC-8164 series) and servo or stepper motor drivers is the foundation for stable system operation. DIN-814Y is a 4-axis interface adapter board designed specifically for this type of requirement. It provides standardized signal routing and convenient wiring terminals, supports Yaskawa series servo amplifiers and universal stepper motor drivers, greatly simplifying system integration work. This article will provide you with a complete DIN-814Y application guide from the perspectives of hardware architecture, interface definition, signal mapping, typical applications, and troubleshooting.

Product positioning and hardware overview

DIN-814Y is a passive adapter board (passive backplane), whose core function is to convert the CN1 (or CN2) high-speed signal interface of the motion control card into industrial terminals that are convenient for 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 designed specifically for Yaskawa ∑ series servo drives, including all signals such as speed command, encoder feedback, enable, alarm, position pulse, etc.

SJ #: A 10 pin simple interface provided for stepper motor drivers, including pulse, direction, enable, alarm, and+5V power output.

Important warning: CNIF # and SJ # on the same axis are directly short circuited inside the PCB (signal lines are connected in parallel). 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 # (10 pin mechanical I/O interface) for connecting limit switches (positive limit PEL, negative limit MEL), origin signal ORG, deceleration signal (PSD/MSD), and reset signal RES. For each axis, a BH # auxiliary interface (16 pins) is also provided to extend other signals defined by Yaskawa (such as absolute value encoder battery, torque command, alarm code output, etc.), making it convenient for users to connect additional functions without changing the main cable.

The board is powered by an external+24VDC power input (CN1), which is isolated to provide power to all optocoupler inputs/outputs, ensuring electrical isolation from the computer side. At the same time, there are LED indicator lights near each axis on the board, which intuitively display the status of PEL, MEL, and ORG, facilitating on-site debugging.

Interface Definition and Signal Explanation

1. CNIF # servo interface (50 pins)

This is the core interface of DIN-814Y, used to connect Yaskawa servo drives (such as SGDV, SGDH, etc.). The following is the analysis of key signals:

Key points of the signal name direction function description project

The simulated voltage (± 10V or 0-10V) of the V-REF output speed command is controlled by the DAC output of the motion control card to regulate the motor speed; Pay attention to impedance matching.

T-REF outputs torque command analog voltage (optional) for torque control mode, usually not used.

OUT+, OUT - differential output pulse signal (Line Driver) is used for position control mode, combined with DIR direction signal to form step/servo pulse command.

DIR+, DIR - The differential output of the output direction signal determines the direction of motor rotation, and the level corresponds to forward/reverse rotation.

EA+, EA -, EB+, EB - Input Encoder A/B differential input receives encoder signals returned by servo drives for position closed-loop and interpolation.

EZ+, EZ - Input encoder Z-phase (zero point) input is used for origin reset and position zeroing.

PSO+, PSO - output encoder S phase (serial data) output Yaskawa absolute value encoder data line (battery powered).

SVON outputs a servo enable signal high (or low, depending on the driver settings) to excite the motor.

ALM input servo alarm signal is valid when the driver fails, and the motion card should immediately stop pulse output.

The INP input positioning completion signal is valid when the servo completes the instruction position, and is used to confirm that it is in place.

The RDY input servo ready signal indicates that the driver has been powered on and has no faults, and can accept commands.

SEN output absolute value encoder reset is used to clear multi turn data or reset the encoder.

BAT+, BAT - The output encoder battery power provides backup power (usually 3.6V) for the absolute value encoder.

P-CON, P-CL,/N-CL input proportional control/positive current clamp/negative current clamp advanced servo parameter control, generally processed by default.

AL01~AL03 output alarm number output (3-digit binary) can read alarm codes and assist in diagnosis.

PL1 output collector open circuit+12V output can provide low current power supply for external sensors.

+24VO output isolation+24V output is provided by an external input power supply after isolation, which can be used to drive photoelectric sensors, etc.
