Surge voltage of 400 V inverter

1. Since the voltage resistance of the standard motor is not improved, it is recommended to use an "insulation-enhanced motor".If you are using an insulation... More Details >>

Notes when inverter capacity is larger than motor capacity

When using one-rank-higher inverter, as you mention, you need to care about the setting of the electronic thermal O/L relay.Setting the electronic thermal O/... 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 >>

Can I drive multiple motors with a single inverter?

You can drive multiple motors with a single inverter.However, since the inverter cannot determine the current of each motor, the electronic thermal O/L relay... More Details >>

Wiring to connector

You can solder the wiring to the connector without using the junction terminal block (option). More Details >>

Selection method of the FR-ABR

The multiple rating is adopted from the FR-A800 series and the motor and the inverter are no longer one-to-one. Thus, considering the combination that the mo... More Details >>

Installation of the FR-PA07

Yes, because the same enclosure cut dimensions is adopted. More Details >>

FR-A800-E

There are some restrictions compared to the FR-A800 (RS-485 communication type). For example, the FR-A8TR is unavailable, and only two option connectors are ... More Details >>

FR-A800-R2R

Yes. It can be carried out like under the dancer feedback speed control. More Details >>

Reduced impact restart

Until now the DC has been applied to perform the frequency search. When Pr.162 = 3 or 13, the impact is reduced by detecting the phase and performing the sea... More Details >>
