Relationship between frequency and output torque

The output torque characteristics of the FREQROL-E500 series are shown in the figure below. Figure 1 More Details >>

FR-RC selection

1. The 100% braking torque means the 100% motor rated torque. Do not consider the continuous regenerative driving based on the braking torque. Consider the r... More Details >>

Changing parameters

Before you change Pr.7 and Pr.8, you must switch to the PU operation mode. Switch to the PU operation mode and change them. More Details >>

Terminal FM

Since the terminal FM is designed with 8 V peak pulse voltage output, it cannot output 10 V.Since the terminal AM is an analog output of 0 V to 10 V, use thi... More Details >>

Output phase loss protection error

- How to find out lost phaseMeasure the three-phase current when the error has occurred.The phase with a small (or no) phase current is lost.- Possibility of... More Details >>

Rated capacity related to harmonic suppression guidelines

The usual inverter input current is determined not by the inverter capacity but by the motor capacity (motor load).Therefore, the input side capacity is not ... More Details >>

EMC compliant filter terminal cover

The SF1258 has the terminal cover.Although the SF1259 to SF1263 do not have the terminal covers and their terminals are bare, rubber tubes to cover them are ... More Details >>

Proper use of AC reactor and DC reactor

1. ACL has the input power factor of approximately 90% and DCL has the input power factor of approximately 95%. Therefore, DCL has a higher input power facto... More Details >>

I want to display the speed on an analog meter.

As the inverter does not display the speed in m/min, let us explain using the speed display in r/min. In this case, set Pr.52 to "6" (operation panel display... More Details >>

Second deceleration time setting

Your suggestion is fine, but note that deceleration stop is naturally not available in case of an inverter error.In addition, considering regenerative power,... More Details >>
