System compatibility
Compatibility description: CC422 belongs to HEIDENHAIN CC series control family. Works with MC420 main computer and UM122 / UM1xx servo power modules. Compatible with HEIDENHAIN linear and rotary encoders, suitable for Fives Giddings & Lewis PIC900 CNC heavy boring mill system.
Function
Function description: CC422 is motion control computer manufactured by HEIDENHAIN. It executes speed and current closed-loop calculation for feed axes. It communicates with CNC main computer, reads encoder position signals and generates PWM commands for power modules. Multiple protective functions will trigger alarm and stop axis movement when overheat, encoder loss or current overload occurs. It is legacy core motion control spare for heavy CNC boring mills.
Installation
Installation steps: Follow lockout/tagout safety procedure before installation. Cut off 24V control power and DC bus power. Install CC422 module into cabinet rack. Connect control power, communication cable to MC420, PWM control cable to UM power module and encoder feedback lines. Load axis parameters via HEIDENHAIN software. Restore power, verify LED indicators, run drive diagnostic and test axis jog movement.
Interface
Interface list: 24VDC control power terminal, MC420 communication connector, PWM control signal terminal, encoder signal interface,on-board POWER / RUN / COM / FAULT LED indicators for HEIDENHAIN CC422 359 651-01.
Diagnostic
Troubleshooting: Axis no movement: Check 24V control power, communication cable connection or parameter mismatch. FAULT LED lit: Encoder communication loss, over-temperature, overload or internal hardware failure. Axis tracking error: Improper servo gain, encoder signal distortion or mechanical friction abnormality.
