Study notes

  • Input ratings: 15 hp with 3-phase input and 5 hp with 1-phase input. Current ratings: 47 A with 3-phase input and 17 A with 1-phase input; variable torque rating is 49 A.
  • Control mode is SVC or V/Hz. Output frequency range is 0.1–599 Hz; carrier frequency range is 2–15 kHz.
  • Native RS-485 (RJ12) protocols are Modbus RTU, Modbus ASCII, and BACnet; port speed is up to 115.2k baud. BACnet has no matching protocol id in this schema.
  • Optional EtherNet/IP and Modbus TCP cards are available; these are not native ports.
  • Three analog input channels accept 0–20 mA, 4–20 mA, or ±10 VDC with 11-bit resolution.
  • Two analog output channels provide 0–20 mA, 4–20 mA, or 0–10 VDC with 10-bit resolution.
  • Eight discrete inputs are rated 24 VDC and are sinking/sourcing. Four discrete outputs are relay/sinking/sourcing, including two Form C (SPDT) relays.
  • Discrete output nominal voltage is 240 VAC and 48 VDC. Relay load current is 3 A/point; discrete load current is 50 mA/point.
  • Integrated dynamic braking and built-in reverse capability. Programming language is ladder.
  • For use with 3-phase induction motors. Mounting is panel or wall.
  • Input signal can be 4–20 mA, voltage, or potentiometer input.

Safety

  • Built-in Safe Torque Off (STO).
  • UL Listed File # E198015.
  • Operating temperature range: -10 to +50 °C.
  • Requires a user-supplied external fuse.
  • CE declaration available; RoHS compliant.
  • NEMA 1 enclosure.
