 Changing the function of analog input terminal
• In the initial setting, terminal 1 is used for analog input of the auxiliary speed setting (auxiliary speed limit), and terminal 4
is used for the speed command.
To use the analog input terminal to input the stall prevention operation level, set Pr.868 Terminal 1 function assignment
and Pr.858 Terminal 4 function assignment to change the function. (Refer to
