Inverter's heat generation quantity
The heat generation quantity while the inverter is outputting the rated current is as follows:1. FR-A520-3.7K: 230 W2. FR-A520-7.5K: 420WThe heat generation ... More Details >>
Pulse train output of terminal FM
Under Advanced magnetic flux vector control, the output frequency varies due to slip compensation. This may cause the output frequency monitor value to chang... More Details >>

As an example, you can use an inverter to feed the cord at the constant speed under dancer control using a combination of the deviation detector and deviatio... More Details >>
Connecting the brake resistor allows for quick deceleration because the regenerative power is processed. (The brake torque increases.)Therefore, when an exte... More Details >>

FR-A500 main circuit wire types
Since the UL standard defines to "Use copper wires (rated at 75?C)", we also recommend the same type of copper wire. More Details >>
Two-rank up maximum short-time torque
It is not possible to generate torque larger than the maximum possible torque of the motor by increasing the inverter's capacity.Even when the inverter is up... More Details >>
