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 >>

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 >>

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 >>

Operation at base frequency or higher

The output frequency is 55 Hz. (For V/F control)When the base frequency is set to 50 Hz, frequencies over 50 Hz is the constant output range.Note that the ma... More Details >>

Comparison with FR-A200E

In addition to speed control, you can also select torque control as well as you can perform position control using an option. The speed control range is as l... More Details >>

Applicable motors

In addition to the dedicated motor (SF-VR series), the SF-JR series motor with an encoder can be used. You can also use a standard motor by combining it with... More Details >>

Noise filter

Noise filtering and harmonics suppression are different matters and you need to install the line noise filter (FR-BSF01) against noise and DCL (FR-BEL) again... More Details >>

Number of inverters that can be connected to a 20 A branch circuit breaker

The basic idea is the same, but the total capacity should be 3.7 kW. (The maximum capacity is also 3.7K.) More Details >>

Speed setting

The high speed command (multi-speed command) is prioritized over the frequency setting potentiometer. It is OK if these are both input simultaneously. When t... More Details >>
