Structural Characteristics: Standalone metal enclosure, compact form factor (7.875″ × 5.00″ × 1.50″ for 4-axis).
Working Principle: The controller executes motion programs from non-volatile memory, processes quadrature encoder feedback at 15 MHz, performs PID computation with feedforward, and outputs ±10 V analog commands or 3 MHz step/direction pulses to drive amplifiers.
Application Scenarios: Industrial automation, robotics, motion control systems, and medical device manufacturing where space is at a premium.
Installation Requirements:
- 20–80 V DC power supply
- Ethernet/USB/RS-232 communication cabling
- Panel or DIN-rail mount in control cabinet
- Connect via optically isolated I/O and analog interfaces
Usage Notes:
- Standalone operation or PC-controlled via Ethernet/USB
- Use Galil Design Kit (GDK) for programming and tuning
- Supports simultaneous execution of up to 8 application programs
- 4-axis version dimensions: 8.1″ × 7.25″ × 1.5″; 5–8 axis version: 11.5″ × 7.25″ × 1.5″
