Giddings & Lewis 503-26606-40 MMC 4 Axis Analog Unit

Technical SpecificationsModel：503-26606-40 Brand：Giddings & Lewis Product Type: Rack mount MMC series 4-axis analog motion control unit for PiC900 CNC system

Module Feature:Function: MMC 4-axis analog motion control unit for G&L PiC900 platform. It performs real-time closed-loop position and velocity calculation for up to 4 servo axes, outputs ±10V analog speed commands to analog servo amplifiers and reads differential quadrature encoder feedback for heavy horizontal boring mills and large machining centers. Axis capacity: Max 4 servo axes Command output: ±10V analog velocity reference for analog servo drives Feedback: Differential A/B/Z incremental quadrature encoder input for each axis Onboard processor: Dedicated real-time motion processor for trajectory calculation and servo loop control LED indicators: OK, READY, COM FAULT, AXIS ALARM diagnostic lights Hardware self-diagnosis: Encoder loss detection, axis tracking error monitoring, analog signal overrange check, watchdog timeout protection Programming software: PiCPro for motor parameter setup, servo gain tuning and module fault diagnosis

Electrical ParametersControl power:24VDC Power consumption:Max 12.5W Onboard lithium backup battery for axis parameter retention

Mechanical & Structure:Mounting:Cabinet rack slot mount Weight:2.3kg Protection class:IP20

Environmental:Operating temperature:0℃ ~ +50℃ Ambient humidity:5~85% non-condensing Certification:CE Status:Manufacturer discontinued legacy MMC analog motion control module

System compatibility503-26606-40 belongs to Giddings & Lewis MMC motion control family. Compatible with PiC900 CPU, G&L analog Centurion servo drives and XSM/FSM/NSM series servo motors. Widely fitted on G&L 70A horizontal boring mills and PMC CNC boring machines.

Function503-26606-40 is MMC 4-axis analog motion control unit manufactured by Giddings & Lewis. It receives motion trajectory commands from PiC900 main CPU, executes closed-loop servo calculation for 4 axes, sends ±10V analog motion commands to analog servo amplifiers, and collects quadrature encoder signals to calculate real-time axis position and tracking error. It is designed for systems using analog servo drives, different from the SERCOS fiber version 503-26606-00. It is a critical 4-axis analog motion spare for legacy heavy G&L CNC machine tools.

InstallationFollow lockout/tagout safety procedure before installation. Cut off 24VDC control power. Mount 503-26606-40 in electrical cabinet rack. Connect 24V control supply, shielded analog command cables and differential encoder feedback cables. Install backup battery before power-up. Configure motor parameters, axis resolution and servo gain via PiCPro. Power on, run module self-test and perform axis homing and positioning test.

Interface24VDC control terminal,multi-channel analog command terminal block,quadrature encoder connectors,backplane gold finger connector,on-board OK / READY / COM FAULT / AXIS ALARM LED indicators for Giddings & Lewis 503-26606-40.

DiagnosticAxis tracking error alarm:Check encoder cable shielding,connector contact or improperly tuned servo gain. COM FAULT:Backplane bus communication failure or module configuration mismatch with PiC900 CPU. AXIS ALARM:Encoder signal loss, analog output overrange or mechanical axis overload.
