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 >>

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 >>

Safety stop function of the FR-D700/FR-E700

It is recommended to install the magnetic contactor on the input side of the inverter for safety. The category 3 can be satisfied without installing it. More Details >>

Safety stop function

Up to three inverters can be connected. When more than four inverters are connected, the inverters may not be recognized because of the voltage drop. More Details >>

FR-A842

The inrush current limit circuit is not built in the FR-A842 (inverter unit). It is built in the FR-CC2 (converter unit), which is combined with the FR-A842.... More Details >>
