Endurance

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 >>

Comparison with E500

The major differences are:- Capacity range- Availability of regenerative brake resistor- Operation of the operation panel- Number of I/O terminals More Details >>

Installing frequency setting potentiometer

When you are inputting analog signals, install the potentiometer within 30 m from the inverter. 　(Refer to "Precaution on Selection and Operation" on the cat... More Details >>

CC-Link

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

Notes when inverter capacity is larger than motor capacity

When using one-rank-higher inverter, as you mention, you need to care about the setting of the electronic thermal O/L relay.Setting the electronic thermal O/... More Details >>

Analog output

The FM output is 0 to 8 VDC pulse. More Details >>

Output voltage measurement

The inverter's output voltage is controlled by switching DC voltage and has a pulse voltage waveform.(It is not a clean sine wave.)Therefore, it cannot be me... 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 >>

Usage

1. Changing frequency to 0 Hz(1) Set Pr.8 (Deceleration time) to 0 second.If the load is large, the stall prevention function may work to lengthen decelerati... More Details >>
