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 >>
Single-phase power supply drive
For a single-phase 200 V power supply, you can use the FR-E520S series for up to 0.75 kW motor.If you use the three-phase 200 V power supply inverter with a ... More Details >>
The following is the case for the FREQROL-A500 series:1. When the R phase or S phase is lost, the inverter stops since it loses the control power supply.2. W... More Details >>
Frequency adjustment using potentiometer
Since the inverter is initially set to 0 Hz for 0 V and 60 Hz for 5 V, you can calculate the frequency for a certain voltage value. The equation is "Output f... More Details >>
Since the FR-A540-0.75K has a brake transistor for resistor regenerative driving inside the inverter, you do not need to use BU. Just remove the jumper from ... More Details >>
How can I have the motor coast to stop?
You can use the following two methods:1. Turn ON MRS at the same time when STF turns OFF.2. Set Pr.10 = 60 Hz, Pr.11 = 0 sec, and Pr.12 = 0% (when the invert... More Details >>
Use Pr.17 (Input terminal assignment) to assign MRS to the terminals DI1, DI2, and DI3. More Details >>
Checking terminals used:Are the terminals MRS and RES open?Are the terminals STR and SD short-circuited correctly?Is the voltage/current switch of the termin... More Details >>
Up to 30 m. (To avoid noise and voltage drop) More Details >>
Keep Y100D turned ON if you are changing the frequency continuously. More Details >>
