Countermeasure against harmonics

Perform calculation given in the harmonic suppression guidelines, and if the limit value is exceeded, you may also need to insert the ACL. Note that you cann... More Details >>

Inverter current value

1. As the measurement condition is unknown, the possible cases are as follows: - If you measured the current on the input side of the inverter, since the cu... More Details >>

Inverter with one-rank higher capacity

An inverter with one-rank higher capacity is often used when a high torque is required for a short period of time. (Examples)- When rapid acceleration/decele... More Details >>

Relationship between frequency and load current

If the load is heavy and the output current is higher than the control value, you can adjust Pr.22 (Stall prevention operation level) to trigger the stall pr... More Details >>

Compressor

You can use an inverter for fan and pump with the compressor, but it is not recommended for an application that the motor load rapidly increases. More Details >>

Monitor output

The FM output is the 1440 Hz, 1 mA pulse train output at full scale. You can input to the programmable controller if it has a pulse train input. A68AD does n... More Details >>

EMC countermeasure

To conform to the EMC Directive when exporting to an EU country, install the filter that conforms to the EMC Directive on the inverter, and take measures acc... More Details >>

Installing reactor for suppressing harmonics

You can connect multiple inverters to a single reactor. In this case, the load seems to be light from the reactor unless all of the inverters are rotating an... More Details >>

Parameter unit

The FR-PU02-1 cannot be used with the FR-B3 series inverters. 　Use the FR-DU04 or FR-PU04. More Details >>

Amount of heat generated

The amount of heat generated by the FR-E500 series inverter is registered in the Mitsubishi Electric FA Global Website Member's page. Refer to the technical ... More Details >>
