Connection diagram
The main speed command differs according to each operation mode (External, PU, communication).
The output signal terminal to be used differs according to the Pr. 190 to Pr. 196 (Output terminal
function selection) setting.
The input signal terminal to be used differs according to the Pr. 178 to Pr. 189 (Input terminal
function selection) setting.
