This configuration is common in small conveyor, pump, and fan applications where only single-phase mains are available but a three-phase motor is preferred for torque and efficiency. ## MODBUS RTU and 400 Hz output for flexible control The drive supports MODBUS RTU over RS485, allowing direct connection to a PLC or SCADA network without an external gateway — the 5 digital inputs and 1 analogue input (0-5 V, 0-10 V, or 0-20 mA) handle local speed and start/stop commands. Output frequency ranges from 0 Hz to 400 Hz, which suits high-speed spindle motors in machine tools or centrifuges where standard 50/60 Hz drives cannot reach the required RPM. The carrier frequency is adjustable from 2 kHz to 14.5 kHz — raising it above 8 kHz reduces motor audible noise but derates the continuous output current, a trade-off worth noting for noise-sensitive environments like textile or printing lines. ## Panel-mount IP20 with screw terminals Housed in a 128 mm high × 68 mm wide × 162.5 mm deep panel-mount enclosure, the drive is rated IP20 — suitable for installation inside a control cabinet where it is protected from dust and accidental contact. All power and control connections are via screw terminals, and the relay output provides a single change-over contact rated 250 VAC for fault signalling or brake release. ## Mature lifecycle — quoted to order Pricing and lead time are confirmed at quote time against the requested quantity; the drive is sourced to order, not held in speculative stock.","metaTitle":"Mitsubishi FR-D720S-042SC-EC VFD, 750W, 4.2A, 1-Phase Input","metaDescription":"Mitsubishi FR-D720S-042SC-EC AC drive, 750W / 4.2A, 200-240V single-phase input, three-phase output.
