Giddings & Lewis 1300.5970 R1 ASIU-A2 Servo Interface Unit Module

Technical Specifications

Model： 1300.5970 R1, ASIU-A2 (2 1/2 Axis Analog Servo Interface Unit)

Brand： Giddings & Lewis

Product Type: Cabinet mount ASIU-A2 analog servo interface breakout unit for PiC900 / MMC CNC system

Module Feature:

Function: ASIU-A2 analog servo interface unit for G&L PiC900 MMC platform. It handles signal breakout, conversion and conditioning for up to 2 full servo axes plus one auxiliary half-axis. It transmits ±10V analog velocity commands to Centurion analog servo drives and receives differential incremental encoder feedback signals back to MMC motion controller for heavy horizontal boring mills and large machining centers.

Servo capacity: 2.5 axes (2 full feed axes + 1 auxiliary axis) Command interface: ±10V analog speed command output Feedback interface: Differential incremental encoder input

Onboard components: Signal buffer circuits, differential line receivers, noise filtering and transient protection circuits

LED indicators: POWER, CMD, ENC, FAULT diagnostic lights

Hardware self-diagnosis: Encoder signal loss detection, analog output overrange alarm, power supply monitoring

Programming software: PiCPro for axis scaling setup and unit diagnostic testing

System compatibility

Compatibility description: 1300.5970 R1 ASIU-A2 belongs to Giddings & Lewis MMC ASIU servo interface family. Compatible with PiC900 MMC motion boards and Centurion analog servo amplifiers. Widely fitted on heavy G&L horizontal boring mills.

Function

Function description: 1300.5970 R1 ASIU-A2 is 2.5-axis analog servo interface breakout unit manufactured by Giddings & Lewis. It serves as external signal conditioning and breakout hardware between MMC motion control board and analog Centurion servo drives. It converts digital motion instructions from MMC to stable ±10V analog speed signals and routes encoder position feedback back to motion controller. Built-in surge suppression protects signals from industrial electrical interference. It is legacy analog servo interface spare for heavy G&L CNC boring mills.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Disconnect 24VDC control power and ±15V analog reference supply. Mount 1300.5970 R1 ASIU-A2 on cabinet backplate. Wire shielded analog command cables and differential encoder cables between ASIU-A2, MMC motion board and servo amplifiers. Configure axis resolution and scaling parameters in PiCPro. Power on unit, verify CMD and ENC LED status, test axis jog, homing and positioning accuracy.

Interface

Interface list: Multi-channel analog command terminals, differential encoder D-sub connectors, 24VDC / ±15V power terminals,on-board POWER / CMD / ENC / FAULT LED indicators for Giddings & Lewis 1300.5970 R1 ASIU-A2.

Diagnostic

Troubleshooting: No axis movement: Inspect analog command cable, loose connector or wrong axis scaling parameter. FAULT LED lit: Loss of ±15V reference supply, encoder signal failure or overvoltage transient. Position jitter: Ground loop noise, poor cable shielding or degraded signal buffer circuit.
