Working Principle Three-phase AC rectifies to DC bus voltage. The drive generates PWM to feed three-phase motor windings. Encoder feedback closes current, velocity, and position loops. Host commands set desired position or velocity; the drive adjusts motor current to track command. Protection circuits monitor current and temperature.
Installation Requirements
- Panel mount with adequate clearance
- Shielded motor power cable
- Shielded encoder cable
- Ground shield at drive end
- Temperature 0 °C to +40 °C
- Set motor parameters and auto-tune after power-up
- Separate main power and control wiring
- Connect motor brake wire
Precautions
- Wait for DC bus discharge before service
- Motor parameters must match nameplate
- Do not disable overtravel limits
- Keep cabinet free of conductive dust
- Store spares in dry packaging
- Check fan operation periodically
- Do not exceed peak current duration
