Benefits & 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.

Pursuing the best performance
– The General-purpose magnetic flux vector control and 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 speed.
– An enclosure surface operation panel‚ which can be attached on an enclosure surface‚ is available as an option.
– 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.
