Mitsubishi FR-D700 Series
Simple and compact inverter
Features
Improved reliability and easy maintenance
- Spring clamp terminals provide high reliability and easy wiring.
- Shutoff circuit (hardware) securely provides emergency output shutoffs.
- The inverter with the safety stop function can comply with the safety standards without incurring too much cost.
- Parameter writing/reading can be restricted with a 4-digit password.
- The lives of the cooling fan and capacitor have been extended.
- Using the self-diagnosis function, the part life warning can be output and the degree of deterioration can be monitored to prevent malfunction.
Pursuing the best performance
- The General-purpose magnetic flux vector control and FR-D700 the auto tuning function enable reliable operation in applications that require large starting torque. (150% 1Hz, · 200% 3Hz (3.7K or lower with the slip compensation))
Easy-to-use (pursuing the easy operation)
- The non-slip, adaptable scroll speed setting dial allows for quick jumps or precise increments based on turning · Filter options reduce the electromagnetic noise speed.
- Setting can be made easily from a personal computer with FR Configurator.
- An enclosure surface operation panel, which can be attached on an enclosure surface, is available as an option. Operation panel for the FR-E500 series inverters can be also connected.
- The inverters with 0.4K or higher capacity have built-in regenerative brake transistors, and their usage can be extended to a lift application.
Environmentally friendly
- Filter options reduce the electromagnetic noise generated at the inverter and enables the compliance with the harmonic suppression guidelines of Japan.

*: Braking torque is the average short-time torque when a motor decelerates to a stop from 60Hz in the shortest time. (It varies with the motor loss.) It is not a continuous regenerative torque. The average deceleration torque becomes lower when a motor decelerates from a frequency higher than the base frequency.
The inverter is not equipped with a built-in brake resistor. Use an option brake resistor for an operation with large regenerative power. Brake unit (FR-BU2) can be also used.
