Operation frequency

I cannot answer clearly because the load is unknown. The operation cycle of operating for 10 seconds and stopping for 10 seconds is OK, but it is questionabl... More Details >>

Countermeasure against the instantaneous power failure with the inverter

The power cannot be supplied to the control power supply separately for the FR-A024/A044 and small type FR-E500. Therefore, the UPS is not available. More Details >>

FR-PA07

No, we have no cable 50 cm long. The optional cables 1 m, 3 m, and 5 m long are available. (1 m: FR-CB201, 3 m: FR-CB203, 5 m: FR-CB205) More Details >>

DC reactor

It can be used since the specifications are the same. Note that the warranty period and expected lifespan for the A700/F700P are inherited. More Details >>

Installation necessity of a DC reactor

Sampling time of FR Configurator2

It depends on the mask count. It is approximately 0.125 [ms] (mask count: 1) to 20 [ms] (mask count: 30). More Details >>

Replacement of the SF-JR with the SF-PR

Since the SF-PR is more efficient compared to the SF-JR, the resistance will decrease and the load current will increase. Check the following two points when... More Details >>

Output phase loss alarm

If the output current is close to 25% of the rated current, output phase loss may occur when one or two phases of three phases go below 25%.Therefore, when a... More Details >>

PWM control

PWM is an acronym for Pulse Width Modulation and varies the switching pulse width of transistors.　This method creates many pulses within a single cycle of th... More Details >>
