Installing parameter unit outside control panel

You can install the operation panel FR-DU04 (or parameter unit FR-PU04) on the enclosure surface by connecting it with the inverter via a cable.To do this, d... More Details >>

Inverter control power supply

To supply power via R1 and S1, 60 VA or higher is necessary for 22K or lower and 80 VA or higher is necessary for 30K to 55K.Note that the rush current of ap... More Details >>

Is the number of writing times of the parameter memory limited?

1. The limit of the parameter writing is 100,000 times. 2. Parameter error occurs. Since the data in the ROM may be broken, the inverter may become unavailab... More Details >>

Built-in regenerative resistor

For both the 200 V and 400 V classes have the built-in regenerative resistor for 0.4 K to 7.5 K.The permissible power is as follows:Capacity: Short-time perm... 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 >>

Winding control

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 >>

Remote operation of the inverter

The wiring length of the start signal (STF etc.) is 30 m or less. The circuit voltage of the control input signals (terminal STF etc.) is 24 VDC and the volt... More Details >>

Coasting

When the inverter output shutoff signal MRS is turned on, the output is shut off immediately without regard to setting of Pr.250. More Details >>

Amount of heat

The inverter (FR-A520-5.5K) itself generates approximately 310 W of heat. This is the amount generated under the inverter rated current 100% load. Since the ... More Details >>
