Product features

The Mitsubishi FR-E720S-050SC-EC is a dependable compact inverter from Mitsubishi's FR-E700 series, intended for regulating three-phase AC induction motors in a variety of industrial applications. One significant advantage of the Mitsubishi FR-E720S-050SC-EC is its superior control technology. It employs sensorless vector control and V/F control to achieve exact speed and torque control even without an encoder, hence saving on hardware expenditures. The inverter also has a high overload capacity-200% of rated current for 3 seconds and 150% for 60 seconds-which reduces downtime due to overload alarms. To safeguard both equipment and personnel, it includes a built-in Safety Torque Off (STO) function that rapidly stops motor torque and avoids unexpected restarts, fulfilling SIL 3/PLe safety regulations.

The Mitsubishi FR-E720S-050SC-EC is also known for its ease of use. It contains a built-in 3-digit LED display for convenient parameter checking, as well as an integrated USB connector that allows direct connection to a PC running FR Configurator 2 for quick setup and monitoring. The inverter also supports Modbus RTU communication via its RS-485 connector, allowing for simple integration with current automation systems. With 6 digital inputs, 2 transistor outputs, 1 relay output, 2 analog inputs, and 1 analog output, it provides versatile connection for a variety of control applications.

The Mitsubishi FR-E720S-050SC-EC is tiny in size (108mm×128mm×141.5mm) and weighs only 1.4kg, making it ideal for narrow control panels. Its IP20 designation protects it against solid objects larger than 12mm, making it ideal for interior industrial use. The inverter also has self-diagnostic mechanisms that monitor its performance and sound alerts for faults, extending its service life. It is RoHS compliant and has CE, UL/cUL, and UKCA certifications to ensure quality and safety in global markets.

Application scenarios

The Mitsubishi FR-E720S-050SC-EC inverter is commonly utilized in small to medium industrial and commercial applications because of its 0.75kW power, compact design, and dependable safety features. As a member of Mitsubishi's FR-E700 family, this inverter is ideal for applications requiring precise speed control and steady performance with small induction motors. The tiny size (108mm×128mm×141.5mm) and low weight (1.4kg) make it ideal for equipment with limited installation space.

Material handling systems, such as small conveyors in factories and warehouses, are one of the Mitsubishi FR-E720S-050SC-EC's primary applications. These conveyors frequently operate for lengthy periods of time and require variable speeds to accommodate various production lines. The inverter's V/F and sensorless vector control enable smooth speed changes, while its 150% overload capacity for 60 seconds eliminates shutdowns due to unexpected load spikes. The built-in Safety Torque Off (STO) function provides additional protection by promptly stopping the motor in an emergency, which is crucial for worker safety around moving parts.

The Mitsubishi FR-E720S-050SC-EC benefits both water treatment and plumbing systems. It is frequently used to operate tiny water pumps in residential structures, small companies, and garden irrigation systems. The inverter saves energy by altering the pump speed based on water demand, unlike traditional fixed-speed pumps. Its Modbus RTU connectivity via the RS-485 port enables personnel to remotely monitor and regulate the pump, eliminating manual checks and maintenance time. The inverter's self-diagnostic mechanism also detects flaws early, preventing water supply interruptions.

FAQ

Q: What is the Mitsubishi FR-E720S-050SC-EC?

A: Mitsubishi's FR-E720S-050SC-EC is a compact and adaptable general-purpose variable frequency drive (VFD) from the FR-E700 series. It is intended specifically for controlling the speed of a three-phase AC motor. The model code specifies a power rating of 0.5 kW (0.67 HP) and a single-phase 200-240V AC input (the "S" in the model). The "-EC" suffix indicates that it is a European Community (CE) compatible model. This inverter is a critical component for achieving energy savings, smooth motor startup, and precise process control in a variety of applications.

Q: How do I program and set parameters on the Mitsubishi FR-E720S-050SC-EC?

A: Programming is simple with the built-in keypad (FR-PU07). You can use menus to adjust fundamental factors such as frequency, acceleration/deceleration times, and motor current. Mitsubishi's FR Configurator2 software can be used on a PC connected via a USB interface cable (available separately) to perform advanced setup or batch programming. This enables easier parameter administration and monitoring of the FR-E720S inverter.
