System compatibility

Compatibility description: 401-34205-22 belongs to Giddings & Lewis Centurion servo family. Compatible with PiC900 CNC controller, MMC / SMP400 motion control boards and G&L HSM series brushless servo motors. Widely used on heavy G&L horizontal boring mills.

Function

Function description: 401-34205-22 is Centurion single-axis brushless servo amplifier manufactured by Giddings & Lewis. It receives motion command signals from the CNC motion controller and converts DC bus voltage into three-phase AC output to drive brushless servo motors. Real-time encoder feedback enables high precision closed-loop axis positioning. Integrated brake chopper absorbs regenerative energy generated during rapid deceleration. It is legacy feed axis servo spare for heavy G&L CNC boring mills.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Disconnect three-phase AC main power and 24VDC control power. Mount 401-34205-22 vertically on cabinet backplate. Wire three-phase AC input, shielded motor power cable and differential encoder feedback cable. Set motor parameters and tune servo gains via PiCPro. Run drive self-test, verify READY LED status, test axis jog, homing and positioning performance.

Interface

Interface list: 3-phase AC terminal block, motor power connector, encoder D-sub port, analog/digital command terminals,on-board POWER / READY / AXIS ALARM / FAULT LED indicators for Giddings & Lewis 401-34205-22.

Diagnostic

Troubleshooting: AXIS ALARM: Encoder cable failure, mechanical overload or tracking error over limit. FAULT LED lit: DC bus voltage anomaly, overcurrent, overheating or internal power circuit damage. Axis hunting: Improper servo gain setting, inadequate brake resistor or poor cable shielding.
