System compatibility

Compatibility description: M.1301.2076 belongs to Giddings & Lewis PiC900 motion control family. Compatible with PiC900 CPU, SERCOS or analog servo interface modules and G&L series servo motors. Widely fitted on heavy G&L horizontal boring mills.

Function

Function description: M.1301.2076 is motion control board manufactured by Giddings & Lewis. It handles real-time trajectory interpolation and closed-loop servo control for machine axes. It communicates with PiC900 main processor over backplane bus, exchanges motion commands and feedback signals with servo drives. The onboard backup battery keeps axis tuning parameters saved during power interruption. It is legacy motion spare for heavy G&L CNC boring mills.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Cut off rack backplane power. Insert M.1301.2076 into rack slot and secure gold finger connector. Install backup battery before power-up. Connect serial diagnostic cable. Configure axis parameters and servo gains via PiCPro. Run self-test and verify axis jog, homing and machining motion performance.

Interface

Interface list: Backplane gold finger connector, serial diagnostic port,on-board OK / RUN / AXIS FAULT / FAULT LED indicators for Giddings & Lewis M.1301.2076.

Diagnostic

Troubleshooting: AXIS FAULT: Servo gain mismatch, mechanical overload or encoder signal loss. FAULT LED lit: Backplane communication failure or onboard memory fault. Parameter loss: Depleted backup battery or poor battery contact.
