Installing frequency setting potentiometer

When you are inputting analog signals, install the potentiometer within 30 m from the inverter. 　(Refer to "Precaution on Selection and Operation" on the cat... 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 >>

All parameters returned to initial values

FR Configurator2

Vector control cannot be selected unless Pr.862 is set to 1. Only the first motor is supported in the motor setting of FR Configurator2. More Details >>

Emergency stop of the FR-A800

For the V/F control and Advanced magnetic flux vector control, the FR-A800 stops only by Pr.1103 Deceleration time at emergency stop. Pr.815 is not affected. More Details >>

Replacement with the FR-B, B3 (A800 specification)

In the A800 base of the FR-B and FR-B3, the Easy setup wizard is not available. Thus, some functions are restricted. More Details >>
