FR-A5CN03

Since the heat sink and fan are not waterproof, you need to enclose them so that they are not exposed to the spray of water. If you use the inverter (heat si... More Details >>

Long wire to terminal FM

Although you can connect an analog or digital indicator to the terminal FM, use an analog indicator since the wiring length is long. (The maximum wiring leng... More Details >>

Is the number of writing times of the parameter memory limited?

1. The limit of the parameter writing is 100,000 times. 2. Parameter error occurs. Since the data in the ROM may be broken, the inverter may become unavailab... More Details >>

Vector control of the inverter

The speed fluctuation ratio under Advanced magnetic flux vector control of the FR-A500 is as follows. Without encoder: ±1% With encoder (with A5AP): ±0. 02 %... More Details >>

Earthing (grounding) of FR-A7NC (E kit)

There is no problem, however, earthing (grounding) from each FG terminal is recommended to avoid the influence of noises. More Details >>

Stop selection

No. During JOG operation, deceleration stop is performed even though Pr.250 is set. More Details >>

Use the AC reactor. More Details >>

MD-CX522

The initial value of Pr.78 (Reverse rotation prevention selection) of the MD-CX522 is "1" (reverse rotation is disabled). When performing forward rotation an... More Details >>

FR-FS

The acceleration time is 60 Hz and 5 seconds, and deceleration time is 60 Hz and 60 seconds. More Details >>

Orientation control

The following reasons are possible. - The signal of Z phase does not exist. (It is not returned normally.) - The setting of Pr.359 encoder rotation direction... More Details >>
