Working Principle DC input power is filtered and regulated to drive the three-phase PWM output stage. Digital control processors close current, velocity, and position loops based on command inputs and motor feedback. The drive supports both standalone operation with stored programs and real-time command following via communication interfaces.
Installation Requirements
- Provide 20-90VDC power supply with adequate current capacity
- Use appropriate wire gauge for 9 Amp peak current
- Mount in ventilated enclosure avoiding direct exposure to contaminants
- Connect motor feedback cables with proper shielding
Operating Precautions
- Ensure DC input voltage remains within specified range
- Do not reverse polarity on DC input connections
- Verify motor current ratings match drive output capability
- Allow thermal recovery time after peak current events
