Inverter drive of 400 V class motor
When the wiring between the inverter and motor is long, surge voltage occurs at the terminal of the motor.This surge voltage deteriorates insulation of the m... More Details >>
Surge voltage of 400 V inverter
No. Although the carrier frequency increases or decreases the switching count, the switching speed is the OFF-to-ON speed of the IGBT element of the inverter... More Details >>
Power factor improving effect by option
Installing the high power factor converter brings the power factor improving effect of 99% or higher.Therefore, when the high power factor converter is used,... More Details >>
Automatic overload control of inverter
The inverter has the current limit function. This automatically controls the frequency so that the preset current value may not be exceeded. (Note that the m... More Details >>
Using the inverter's input terminal, you can use up to 15 speeds.This function is supported by the current 500 series products (A500, F500, E500, and S500).U... More Details >>
Current input switching operation
With your setting, since Pr.60 assigns the OH function to the terminal PL, and terminals RL and SD are open, an external protection error occurs. (It does no... More Details >>
Fault contact state when input side p...
The NC contact does not open when the power supply is cut off whether the inverter is operating or ceased.When the input side power supply is cut off, the DC... More Details >>
The operation panel of the FR-S500 is not detachable.For the FR-S500-○○K-R (compatible with RS-485 communication), you can install the FR-PU04 on the enclosu... More Details >>
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 >>
