System compatibility

Compatibility description: M.1302.8130 belongs to Giddings & Lewis PiC900 MMC SmartDrive servo family. Compatible with PiC900 CNC controller, M.1302 series MMC motion boards and G&L HSM brushless servo motors. Widely installed on heavy G&L horizontal boring mills.

Function

Function description: M.1302.8130 is single-axis digital MMC servo amplifier manufactured by Giddings & Lewis. It communicates with MMC motion controller through SERCOS optical fiber ring to receive synchronized motion instructions. It converts DC bus power to three-phase AC output to drive brushless servo motors. Encoder feedback signal is collected in real time to realize high precision closed-loop control. Built-in brake chopper dissipates regenerative energy generated during axis deceleration. It is legacy heavy-duty single-axis servo spare for G&L CNC boring mills.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Disconnect main three-phase AC power and 24VDC control power. Mount M.1302.8130 vertically inside electrical cabinet. Wire three-phase AC input, shielded motor power cable, differential encoder cable and SERCOS fiber ring. Configure motor parameters and servo gain by PiCPro or MMCPro. Run drive self-test, verify READY indicator, test axis jog, homing and positioning performance.

Interface

Interface list: 3-phase AC terminal block, motor power connector, encoder D-sub port, SERCOS fiber TX/RX ports,on-board POWER / READY / AXIS ALARM / FAULT LED indicators for Giddings & Lewis M.1302.8130.

Diagnostic

Troubleshooting: AXIS ALARM: Encoder cable damage, mechanical overload or position tracking error exceeding threshold. FAULT LED lit: DC bus voltage anomaly, overcurrent, overtemperature or internal circuit damage. Axis chatter: Improper servo gain value, insufficient brake resistance or poor cable shielding.
