1. How much is the sensitivity current? When the sum of the three-phase output current of the inverter reaches approximately 70% of the inverter rated curren... More Details >>
The inverter uses PWM control to change the output voltage and frequency to vary the motor speed. PWM stands for Pulse Width Modulation. Voltage is chopped i... More Details >>
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 >>
I want to synchronize the Z200 and E500.
If you are using analog voltage commands, connect the voltage inputs to the FR-E500 and FR-Z200 in parallel to equalize inputs to both units and speeds are s... More Details >>
The current monitor displays the average value of the three-phase current. The three-phase voltage is not incorporated for the voltage monitor. The output vo... More Details >>

Yes. Set parameters as below.For FR-E500Set Pr.79 =3, and Pr.146= 0.Multi-speed is prioritized.For FR-S500Set Pr.79 = 3, and Pr.53 = 1.Multi-speed is priorit... More Details >>
UL standard certification number
The UL standard certification numbers (UL Listing Card No.) of the FR-E500, FR-A500, and FR-A200 are as follows: FR-A200 series??????E131592FR-A500 series???... More Details >>
General-purpose magnetic flux vector control is effective at low speed under a heavy load.To shorten the acceleration time, use Pr.44 to set the second accel... More Details >>
Parameter No.79 (Operation mode)
You cannot cancel multi-speed command input. When the multi-speed command is input from the terminal, you cannot use the potentiometer. Use the inverter so t... More Details >>
Speed change due to power supply volt...
1. The output frequency satisfies the "control specification/frequency precision" even when the power supply voltage changes, but the output voltage cannot r... More Details >>
