Countermeasure against noise and leakage current during low-noise operation

The following two major countermeasures against noise are available: - Keep the noise source and partner device apart from each other.- Install a noise filte... More Details >>

Parameter unit FR-PU03

You can use it with the FR-A200 (E) and FR-A100 (E) series. (Note) Use the connection cable (option). You cannot use it with the FR-Z and FR-U series (except... More Details >>

Comparison of noise between FR-A100 and FR-A100E

The setting ranges of the carrier frequency are:- FR-A100: 2 kHz to 14.5 kHz- FR-A100EXCELLENT: 0.7 kHz to 14.5 kHzThe range of the FR-A100EXCELLENT is exten... More Details >>

Auto tuning enabled motor

Auto tuning targets an induction motor. 1. You can perform auto tuning on a wound rotor motor. After performing auto tuning, check operation in test run. 2. ... More Details >>

Advanced magnetic flux vector control

Check the parameters necessary for tuning again.Check if Pr.9 (Electronic thermal O/L relay) and Pr.81 (Number of motor poles) are set correctly. More Details >>

Inverter setup

Set the parameters below. For other parameters, keep the initial settings.1.　Set Pr.122 (Communication check time interval) to other than "0". ("9999" is OK.... More Details >>

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 >>

Pulse train output of terminal FM

Under Advanced magnetic flux vector control, the output frequency varies due to slip compensation. This may cause the output frequency monitor value to chang... More Details >>
