Pulse frequency characteristics of terminal FM

The terminal FM output pulse is directly proportional to the inverter output frequency.With the initial setting, 1440 pulses/sec are output at 60 Hz (Pr.55),... More Details >>

Monitoring current value

With the FREQROL-U100 series, pressing and holding the [SET] switches to the current monitor. More Details >>

Frequency display deviation

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 >>

CC-Link

Already released.Unlike the E520, you need to purchase the optional card FR-E5NC. More Details >>

Winding control

As an example, you can use an inverter to feed the cord at the constant speed under dancer control using a combination of the deviation detector and deviatio... More Details >>

Fault contact when connecting separate power supply for each control circuit

Since the inverter's fault contact is an NC contact, it does not open unless a fault occurs.Therefore, when the control power supply (and main circuit power ... More Details >>

Reset selection

The specifications of the FR-V200E series do not allow for choosing from "Reset input always enabled" and "Reset input enabled only when the protective funct... 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 >>

Reversible operation of agitator

When the inverter's forward and reverse terminals are switched instantaneously, the inverter decelerates and then switches the rotation direction. It can swi... More Details >>

Regenerative brake resistor

The brake resistor is not built in the inverter. Purchase the optional resistor and connect it to the inverter.Inverter only (without resistor)Continuous reg... More Details >>
