Coasting to stop method

Use Pr.17 (Input terminal assignment) to assign MRS to the terminals DI1, DI2, and DI3. More Details >>

400 Hz output setting

Change Pr.18 (High speed maximum frequency) to 400 Hz.If you are using the analog command to set the frequency, calibrate the 400 Hz frequency with Pr.903. More Details >>

Start command, speed command

You can do so by setting Pr.339 (Communication speed command source) = 1 (external).　　 More Details >>

RS-485 communication

1. You can set Pr.117 for "n1" (Station number) of the FR-S500 for the D700/E700/F700PJ series.2. You can set Pr.338, Pr.339, and Pr.342 for "n8" (Operation ... More Details >>

Auto tuning

Vector control performs high-accuracy calculation using the motor constant. Therefore, to perform vector control operation, the inverter must recognize the m... More Details >>

Can a brake resistor or brake unit be connected?

You can connect them to the FR-A024 inverter 0.4 to 3.7K. (You cannot connect them to 0.1K and 0.2K.)Available brake resistor options include the FR-ABR high... More Details >>

Speed does not exceed 46 Hz

Since the inverter displayed "0.00" instead of an error when the inverter speed dropped to 0 Hz and stopped by holding the winding machine by hand, it is con... More Details >>

Difference between use with A100 and other types

Similarly to the FR-A200 and A500, four or more filters should be used also for the FR-A100. 　In short, it is OK if the wire penetrates the filter four times... More Details >>

Detection of the motor load

An inverter is used to rotate a motor but it cannot be used to detect whether the belt is broken or not. However, the magnitude of the load will change when ... More Details >>

FR-HC2

The power of MC1 is supplied from the terminals across R2 and S2 of the outside box. Either phase of R2 or S2 may be lost. More Details >>
