System compatibility

Compatibility description: 401-30246-00 belongs to Giddings & Lewis Centurion servo motor family. Compatible with DSM series servo drives, PiC900 MMC motion control boards and PiC900 CNC system. Widely installed on heavy G&L horizontal boring mills.

Function

Function description: 401-30246-00 is brushless AC servo motor manufactured by Giddings & Lewis. It converts three-phase power output from servo amplifier into mechanical rotary motion to drive machine feed axes. The integrated incremental encoder sends real-time position and speed feedback signals back to motion control board, enabling high precision closed-loop positioning. Built-in thermal sensor protects the motor against overload overheating. It is legacy heavy-duty servo motor spare for G&L CNC boring mills.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Cut off servo drive AC power and 24VDC control supply. Mount motor to machine axis via flange. Connect three-phase motor power cable and shielded encoder feedback cable. Configure motor parameters via PiCPro or DSMPro. Run motor identification, then test axis jog, homing and heavy load positioning performance.

Interface

Interface list: 3-phase motor power terminal, encoder feedback connector, thermal sensor wiring port,on-board encoder status LED indicator for Giddings & Lewis 401-30246-00.

Diagnostic

Troubleshooting: Motor cannot rotate: Check servo enable signal, motor power wiring or encoder cable breakage. Overheat alarm: Excessive mechanical load, poor ventilation or damaged thermal sensor. Position deviation: Encoder signal loss, loose shaft coupling or improper servo gain.
