5.12.6 Bias and gain for torque (magnetic flux) and set
voltage (current)
Changing the function of analog input terminal
• The initial value for terminal 1 used as analog input is set to speed setting auxiliary (speed limit auxiliary), and terminal 4 is
set to speed command (speed limit). To use the analog input terminal as torque command, torque limit, or magnetic flux
command, set Pr.868 Terminal 1 function assignment, Pr.858 Terminal 4 function assignment to change the function.
(Refer to page 410.)
The magnetic flux command is valid under vector control only.
The magnitude (slope) of the torque can be set as desired in relation to the torque setting signal (0 to 5 VDC, 0 to 10
VDC, or 4 to 20 mA).
Use Pr.73 Analog input selection or Pr.267 Terminal 4 input selection to switch among input 0 to 5 VDC, 0 to 10 V,
and 4 to 20 mA. (Refer to page 406.)
