FR-E520 operation mode (Pr.79) selection

The FR-E500 manufactured before May 1998 behaved as you mentioned, and the potentiometer becomes unavailable once you set the frequency on the operation pane... 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

Yes. Set Pr.89 (Speed control gain) to "0". More Details >>

CC-Link

You cannot monitor the running frequency and conveyor speed (machine speed) simultaneously.The inverter does not have a function to output them simultaneously. 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 >>

When motor current is large

If the parameters related to the output voltage are not changed from the initial setting, it is unlikely that the output current at 55 Hz and 60 Hz is double... More Details >>

Suggestion for replacement of inverters

We do not offer book type inverters. Therefore, the S500 is recommended to replace the Z123 because of its compact design. If regenerative driving matters, c... More Details >>

Operation by single-phase power supply

Similarly to the FR-A220, single-phase power supply operation is possible by reducing the inverter's output current.Ensure that the output current is smaller... More Details >>

Differences between type A and type B

MR-J4-A receives the motor drive command by general pulse train and MR-J4-B does by the optical communication, SSCNET III/H of our motion network. For the de... More Details >>
