Turn ON the monitor command RYC.

Check if signals that are ON when the programmable controller's transistor output starts are always ON.

You can write frequency setting by setting Pr.339 (Communication speed command source) to "0".

You can change the full-scale value by changing Pr.55 (Frequency monitor reference). The initial setting is 60 Hz.

With the monitor indicator "1", there is no problem with the parameter setting of auto tuning. Check if the terminals MR

Set Pr.55 (Frequency monitoring reference) of the first inverter to 70 Hz.

The initial value of Pr.872 is set to "1" (Valid) because the A701 have regeneration unit built-in and an overvoltage ma

Up to 42 units can be connected. (When only inverters are connected)

Considering voltage drop of the internal power supply and influence by noise, the wiring length should be 30 m or less.

Since Pr.3 (Base frequency) is a parameter to set the rated motor frequency, setting it to 80 Hz does not increase the f
