AutomationDirect GS21-22P0

The GS21-22P0 is an enclosed DURApulse GS20 series general-purpose AC variable frequency drive from AutomationDirect. It takes single-phase 230 VAC input and produces three-phase 230 VAC output for a 2 hp motor, using selectable SVC, V/Hz, FOC or torque control modes. It includes RS-485/USB communication, analog and discrete I/O, and integrated dynamic braking.

Study notes

  • Input is 1-phase 230 VAC; output is 3-phase 230 VAC.
  • Motor rating is 2 hp with 1-phase input; rated amperage 7.5 A, variable torque amperage 8.5 A.
  • Control modes selectable: SVC, V/Hz, FOC or torque.
  • Communication ports are (1) RS-485 (RJ45) and (1) USB B, at speeds up to 115.2k baud.
  • Carrier frequency range 2–15 kHz; output frequency range 0.1–599 Hz.
  • Analog I/O: 2 input channels (0–20 mA, 4–20 mA, ±10 VDC; 10-bit and 12-bit) and 1 output channel (0–20 mA, 4–20 mA, 0–10 VDC; 10-bit).
  • Digital I/O: 7 discrete inputs (24 VDC, sinking/sourcing) and 3 discrete outputs (240 VAC and 48 VDC, relay/sinking/sourcing), including one Form C (SPDT) relay.
  • Discrete output load current: 3 A/point relay, 50 mA/point discrete.
  • Integrated dynamic braking is included; there is no integrated EMI filter and the drive is not internally bypassed.
  • Mounting is panel or wall with spring clamp terminals; programming language is ladder.
  • Optional EtherNet/IP and Modbus TCP card available; EtherNet/IP is not provided on the drive itself.
  • Intended for 3-phase induction and permanent magnet AC motors.
