Imbalanced input and output side power supplies

1. In general, the input power of the inverter is always larger than the output power because the inverter loss is added to the motor loss. 2. In both of cas... More Details >>

Inverter circuit breaker selection

Since the inverter leakage current is in proportion to the switching voltage of the transistor of the main circuit, the leakage current for the 400 V system ... More Details >>

Coasting

When the inverter output shutoff signal MRS is turned on, the output is shut off immediately without regard to setting of Pr.250. More Details >>

Load current limit of inverter

You can input current from the terminal AM of the inverter to the programmable controller (for A/D conversion) and control the speed with the software of the... 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 >>

Common connection of the terminal SD

There is no problem for only the terminal SD connection because undesirable current will not be flown. More Details >>

Operation mode setting

The stop-on-contact control does not function in the combined operation mode. 　Perform the control in the External operation mode. More Details >>

Operation panel and FR-PA07

Since the operation panel and PU connector cannot be specified for command source at the same time, they cannot be used together. More Details >>

Brake resistor

Connect the brake resistor to the terminal P and terminal PR. (For the FR-A700-7.5K or lower, remove the jumper of the terminals PR and PX.) Do not remove th... More Details >>

Brake resistor

The brake resistor is MRS120W200. More Details >>
