System compatibility401-34402-50 belongs to Giddings & Lewis Centurion servo family. Compatible with PiC900 CNC control platform, MMC motion control boards and XSM/FSM/NSM series G&L servo motors. Widely fitted on G&L 70A horizontal boring mills and PMC CNC boring machines.

Function401-34402-50 is Centurion 30A servo amplifier manufactured by Giddings & Lewis. It receives trajectory commands via SERCOS fiber bus or ±10V analog signal, regulates output current to drive brushless servo motor, and reads encoder feedback to form closed-loop axis control. It integrates full protection functions for heavy intermittent cutting load conditions. It is critical servo power spare for legacy heavy G&L CNC machine tools.

InstallationFollow lockout/tagout safety procedure before installation. Disconnect 3-phase 230VAC main power and 24VDC control supply. Mount 401-34402-50 on cabinet rack. Connect main AC power, shielded motor power cable, encoder feedback cable and SERCOS/analog command cable. Configure motor parameters and servo gain in PiCPro. Power on, run drive self-test and perform axis homing and positioning test.

Interface3-phase AC input terminal, motor power terminal, encoder feedback connector, SERCOS fiber port, analog command terminal block,on-board POWER / READY / AXIS ALARM / FAULT LED indicators for Giddings & Lewis 401-34402-50.

DiagnosticNo axis movement:Check 230VAC main power,24V control power or servo enable signal. AXIS ALARM:Overcurrent, motor short circuit, encoder signal loss or mechanical overload. FAULT LED lit:Overtemperature, DC bus overvoltage/undervoltage or internal hardware failure.
