System compatibility

Compatibility description: DSM175 belongs to Giddings & Lewis Centurion servo family. Compatible with PiC900 CPU, MMC motion control modules and G&L series brushless servo motors. Widely fitted on heavy G&L horizontal boring mills.

Function

Function description: DSM175 is Centurion DSM single-axis servo drive manufactured by Giddings & Lewis. It supports dual command modes including SERCOS fiber digital ring and ±10V analog signal. It converts DC bus power into regulated three-phase output to drive brushless servo motors, reads encoder feedback signal to achieve closed-loop position and speed control. It is used for high power feed axes of heavy CNC boring mills. It is legacy servo amplifier spare for heavy G&L CNC machine tools.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Disconnect main AC power and 24VDC control power. Mount DSM175 on cabinet backplate. Connect AC input cable, shielded motor power cable, encoder feedback cable and SERCOS/analog command wiring. Install external brake resistor if needed. Configure motor parameters and servo gains via PiCPro or DSMPro. Run drive self-test and verify axis homing and motion performance.

Interface

Interface list: AC power terminal block, motor power terminal, encoder D-sub connector, SERCOS fiber ports,on-board POWER / READY / AXIS FAULT / FAULT LED indicators for Giddings & Lewis DSM175.

Diagnostic

Troubleshooting: AXIS FAULT: Encoder signal missing, mechanical overload, tracking error exceed threshold. FAULT LED lit: Overtemperature, DC bus voltage abnormality or internal hardware damage. Intermittent vibration: Improper servo gain, insufficient brake resistance or poor shielding.
