Structures of dedicated motor

We offer the following: <<Dedicated motor model variation>>- With standard legs (SF-VR__)5.5 kW, 7.5 kW, 11 kW, 15 kW, 18.5 kW, 22 kW, 30 kW, 37 ... More Details >>

Torque limit

When the second torque limit is used, the settings of Pr.816 and 817 are valid. More Details >>

FR-A800-R2R

Yes, it is. However, it is not suitable for the low speed regenerative side. It is also recommended to use a dedicated control for winding/unwinding applicat... More Details >>

FR-A800-GF

Yes, the options are the same as the FR-A800 standard model. Note that two options can be added at maximum. (One option is already used as standard.) Other c... More Details >>

Using existing potentiometer by replacing inverter

It is OK if the resistance value of the speed varying potentiometer's resistance is 2 kΩ.Use the speed varying potentiometers used with the existing inverter... More Details >>

Current value display

The motor-generated torque elements have the following relationship:Torque T = K I V/FK: ConstantI: CurrentV: VoltageF: FrequencyThe inverter regularly perfo... More Details >>

Influence on inverter at motor coasts to stop

An induction motor does not act as a power generator unless voltage is applied to it.Therefore, just rotating due to coasting does not affect the inverter. More Details >>

Can I use a motor of which capacity is larger than the inverter capacity?

Even when the actual load (torque) is half of the motor capacity, the current output from the inverter to the motor is not reduced to the half. Therefore, it... More Details >>

IPM motor drive

Overshooting of the speed due to the acceleration/deceleration may be the cause. Overshooting is more likely to occur when the load inertia is too high. As a... More Details >>

Stop-on-contact control

When the brake sequence function is enabled, the RT signal is disabled and the stop-on-contact control cannot be performed. More Details >>
