Mitsubishi Inverter FR-E700 Series:

Features

• Pursuing the best performance--top level of driving performance in a compact body.

Advanced magnetic flux vector control enables accurate start-ups for general-purpose industrial machines (200% 0.5Hz (3.7K or lower)

Improved short-time permissible overload (200% for 3s) provides powerful and consistent driving . Torque limit and current limit functions are available

• Easy-to-use (Outstanding operability and diverse expandability) 

The non-slip , adaptable scroll speed setting dial allows for quick jumps or precise increments based on turning speed. The operation mode can be selected  in simple steps. This Series has USB which enables easy setting from a personal computer with FR Configuration. Plug-in options are available to add digital inputs/analog outputs and to support different communication networks. For the customers who need more than the standard terminals, the option blocks, such as the 2-port RS-485 terminal block , are available. The inverters with 0.4K or higher capacity have plug-in regenerative brake transistors, which enable use for lift applications. An enclosure surface and is available as an option. The operation panel of the FR-E500 series can be also connected.

• Compact and space-saving

The mounting dimensions are the same as the conventional FR-E500 model to keep backwards compatibility. Space can be saved with the side-by-side installation. 

• Improved reliability and easy maintenance 

Spring clamp terminals provide high reliability and easy wiring. (FR-E700-SC/NF/NC) . Shutoff circuit (hardware) securely provides emergency output shutoffs. The inverter with the safety standards without  incurring too  much cost. (FR-E700-SC/NF/NC).  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. The removable control circuit terminal block simplifies replacement work.

•  Environmentally friendly

Filter options reduce the electromagnetic noise generated at the inverter and enables compliance with the harmonic suppression guidelines of japan.
