When consuming the regenerative power with the brake resistor, the brake transistor is triggered at a certain voltage to make the brake resistor use the rege... More Details >>
Setting Pr.37 to the machine speed at 60 Hz switches the frequency monitor to the rotations per minute monitor.Note that the speed setting must be input in a... More Details >>
The estimated lives of the parts of the FREQROL-E500 are as follows: Cooling fan at surrounding air temperature of 35 deg C???30,000 hrsPower supply smoothin... More Details >>

It rotates in the forward direction while STF is ON.And then, when STR is turned ON and STF is turned OFF, the inverter decelerates down to 0 Hz within the s... More Details >>
If you are using an external VR, influence by noise is probable.Setting Pr.74 (Input filter time constant) to a higher value stabilizes the frequency command... More Details >>
General-purpose magnetic flux vector control is effective at low speed under a heavy load.To shorten the acceleration time, use Pr.44 to set the second accel... More Details >>
The major differences are:- Capacity range- Availability of regenerative brake resistor- Operation of the operation panel- Number of I/O terminals More Details >>
Already released.Unlike the E520, you need to purchase the optional card FR-E5NC. More Details >>
Connecting the brake resistor allows for quick deceleration because the regenerative power is processed. (The brake torque increases.)Therefore, when an exte... More Details >>
