Connection with pole change motor

Since the inverter allows for changing speed, fix the number of poles when using the pole change motor. It is recommended to fix the number of poles to four ... More Details >>

Torque characteristic at low speed

Torque is not guaranteed for slower than 0.5 Hz. Therefore, no data for this is published. Also, no torque is generated at 0 Hz. More Details >>

Faults history upon power failure

When an instantaneous power failure of 100 msec or longer occurs, the inverter is reset* and it is not recognized as a fault. Since it is not recognized as a... More Details >>

Power supply capacity

Since the input power factor is improved to approximately 1, the power supply capacity can be reduced to 2/3 to 3/4 of an inverter without a power factor imp... More Details >>

How much low-speed torque can be output?

By choosing the General-purpose magnetic flux vector control and slip compensation function, you can output torque of 150% or more at 1 Hz (200% or more at 3... More Details >>
