The C-arc controller is a digital control solution for controlling the tension and speed of EDM wire in a custom wire EDM machine. The controller works by reading out a load cell that senses the tension in the wire and outputs the setpoints for the wire tension and wire speed servos in the C-arc.
Features:
- Digital control
- Industrial optically isolated RS-485 interface, with configurable termination
- Integrated high bandwidth load cell amplifier, with high robustness against EMC radiation from EDM
- Fully configurable PID+ controller for tension force control
- Calibration feature for wire tension
- Calibration feature for wire speed
- Supports multiple servo types (see manual for details)
- Easy to understand graphical PC user interface
- Can also be operated with a simple serial terminal and human readable ASCII commands
- Digital isolated enable/disable wire control input
- Automatic wire break detection and signalling by an optically isolated digital output
- Memory for flashing default settings
- Load cell offset compensation adjustment
- Update firmware through a standard USB cable
- Full metal shielded enclosure
