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
