Current increase at motor stop

If the current increases when the motor stops under V/F control (at low speed under a light load), the motor is considered to be in the overexcitation state.... More Details >>

Availability of parameter unit

You cannot use the FR-PU04 with the FR-HC. 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 >>

Consideration on thermal

A motor overheats (the current increases) when the load is heavy.When the electronic thermal O/L relay works, you need to mitigate the load.If the current is... 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 >>

Switching between high speed and low speed

As you mention, when the inverter is operated only with STF without inputting the speed command signal, the minimum frequency must be set to 10 Hz.However, a... More Details >>

Installation method

If multiple line noise filters are wound without clearance between them, the noise reduction effect corresponding to the number of filters cannot be obtained... More Details >>

Can you provide the CAD data?

The CAD data is found on the member's page of Mitsubishi Electric FA Global Website. More Details >>

Size of the crimp terminal

Because the crimp terminal of 3.5 sq is out of JIS standard. The 5.5 sq crimp terminal can also fix the 3.5 sq cable. More Details >>

Cumulative pulse monitor

The count is resumed from 0. Thus, the times of the overflow is reset. More Details >>
