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 >>

Combination with power factor improving reactor

It cannot be combined with the power factor improving reactor. (Since the power factor is further improved by the high power factor converter, it is not requ... More Details >>

Inverter selection when multiple inverters are to be connected

Be sure to use a high power factor converter with the capacity higher than the total capacity of the inverters connected. (Note: One or more of the inverters... More Details >>

Using both types of power factor improving reactors

Yes.By using both types of reactors together, you can reduce the outgoing harmonic current.For examples of harmonics reduction, refer to the value in the har... More Details >>

Frequency does not rise with blower

Our suggestion is to adjust the following parameters:1. Set Pr.14 = 0. If the V/F pattern for variable-torque load (Pr.14 = 1) is used, the current may incre... More Details >>

FR-A8NC

The torque limit setting is defined as an absolute value. Thus, when -100% is written to the torque limit, the torque is limited at 100%. More Details >>
