Mitsubishi Inverter FR-D700 Series

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 standard 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 the auto tuning function enable operation in applications that require large starting torque. (150% 1Hz, 200% 3Hz (3.7K or lower with the slip compensation))

• Easy-to-use (Pursing the easy operation)

The non-slip, adaptable scroll speed setting dial allows for quick jumps or precise increments based on turning 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.
