Working Principle The S20660-SRS converts single or three-phase AC input to a regulated DC bus voltage. Digital control processors close current, velocity, and position loops at high frequency. The three-phase PWM output stage delivers 6 Amps continuous to brushless servo motors. SynqNet communication enables the drive to receive motion commands from a central controller and report actual position, velocity, and status in real time. The network architecture supports up to 32 nodes with deterministic cycle times appropriate for coordinated multi-axis motion.
Installation Requirements
- Install in electrical enclosure with IP20 minimum protection
- Provide 120/240 VAC supply with adequate capacity for 1 kW output
- Use shielded FireWire cables for feedback and RJ45 cables for SynqNet
- Terminate SynqNet network properly at both ends to prevent signal reflections
- Maintain minimum clearance around heatsink for thermal dissipation
Operating Precautions
- Confirm motor continuous current rating matches 6 Amp drive capability
- Verify SynqNet node configuration matches master controller setup
- Monitor drive temperature during sustained peak current operation
- Configure safe stop behavior for communication loss scenarios
- Back up motion task programs and parameter sets before modifications
