Bias and gain for torque (magnetic flux) and set voltage (current)

Sensorless Sensorless Vector Sensorless
The magnitude (slope) of the torque can be set as desired in relation to the torque setting signal (0 to
5 V DC, 0 to 10 V DC, 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 V DC, 0 to 10 V, and 4 to 20 mA. (Refer to page 5-406.)

The parameter number in parentheses is the one for use with the LCD operation panel and the
parameter unit.
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 aux-
iliary), and terminal 4 is set to speed command (speed control). To use the analog input terminal as
torque command, torque limit, or magnetic flux command, set Pr. 868 "Terminal 1 function assign-
ment", Pr. 858 "Terminal 4 function assignment" to change the function. (Refer to page 5-411.)
The magnetic flux command is valid under vector control only.
