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 >>

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 >>

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 >>

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 >>

0 Hz output of inverter

When the command frequency is 0 Hz, the inverter does not generate output and the voltage is 0 V. More Details >>

Manual contactor on output side of drive unit

The low-voltage manual contactor is intended to prevent electric shock during inspection and maintenance of the drive unit.The MELIPM series motor is a synch... More Details >>

Brake unit selection

Since the FR-A540-0.75K has a brake transistor for resistor regenerative driving inside the inverter, you do not need to use BU. Just remove the jumper from ... More Details >>

Motor heat generation

The surface temperature of approximately 70?C is OK.The following shows the MM-CF352 frame temperature for reference.(Actual temperature rise depends on how ... More Details >>

Changing parameters

Before you change Pr.7 and Pr.8, you must switch to the PU operation mode. Switch to the PU operation mode and change them. More Details >>

Current input switching operation

With your setting, since Pr.60 assigns the OH function to the terminal PL, and terminals RL and SD are open, an external protection error occurs. (It does no... More Details >>
