- RoHS compliant construction
Material Composition:
- Housing: Aluminum die-cast with anodized finish
- PCB: FR-4, multi-layer, conformally coated
- Connectors: Gold-plated pins, MIL-spec quality
Applicable Industries:
- Milling machines (3-axis vertical/horizontal)
- Drilling and tapping centers
- Routing and engraving machines
- Laser cutting (3-axis)
- Waterjet cutting (3-axis)
- EDM (Electrical Discharge Machining)
Installation Requirements:
- Mount on DIN rail TS 35 inside Power Panel or separate control cabinet
- Encoder cables (incremental, 1 Vpp RS-422) must be shielded and grounded at one end
- Limit switch wiring: normally closed (NC) safety configuration recommended
- Spindle drive connection: analog 0-10 V or PWM signal
- Ensure proper earthing of all metallic machine parts
Usage Notes:
- Perform axis homing (reference return) before first operation — G28 command
- Do not exceed maximum look-ahead block count — causes path deviation
- Backup CNC programs to external storage daily — programs are stored in volatile memory by default
- Servo tuning must be performed by qualified personnel — incorrect gains cause oscillation or following error
