PARAMETERS
5.12.2 Analog input terminal (terminal 1, 4) function
assignment
• Concerning terminal 1 and terminal 4 used for analog input, the frequency (speed) command, magnetic flux command,
torque command, and other similar commands are usable. The functions available are different depending on control mode
as shown in the table below. (For control mode, see page 164.)
• Terminal 1 functions under different control modes
• Terminal 4 functions by control
NOTE
• When Pr.868 = "1" (magnetic flux command) or "4" (stall prevention/torque limit), the terminal 4 function is enabled whether
the AU terminal is turned ON/OFF.
