Calibration example of terminal 4
• 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.
Adjustment by changing the torque without adjusting the current (voltage).
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:
