13. (T) Multi-Function Input Terminal Parameters
13.5 Torque (magnetic flux) setting current (voltage) bias and gain
• Use C40 (Pr.933) to set the torque to the 20 mA input of the torque command current (0 to 20 mA).
• There are three methods to adjust the bias/gain for torque setting current (voltage).
Adjustment by applying current (voltage) between terminals 4 and 5 to set the current (voltage) at the bias/gain torque.

Adjustment by selecting the current (voltage) at the bias/gain torque without applying current (voltage) between terminals
4 and 5.

NOTE
• Always calibrate the input after changing the voltage/current input signal with Pr.267 and the voltage/current input selection
switch.
 Display unit changing for analog input (Pr.241)
• The analog input display unit (%/V/mA) can be changed for analog input bias/gain calibration.
• Depending on the terminal input specification setting of
Pr.73 (Pr.267) , the units of the displayed values of C39 (Pr.932)
and C41 (Pr.933) change as shown below:

Pr.241 = "0" (initial value) Pr.241 = "1"
0 to 5 V input 0% to 100% (0.1%) 0 to 5 V (0.01 V)
0 to 10 V input 0% to 100% (0.1%) 0 to 10 V (0.01 V)
0 to 20 mA input 0% to 100% (0.1%) 0 to 20 mA (0.01 mA)
