(T) Multi-Function Input Terminal Parameters
● There are three methods to adjust the torque setting voltage (current) bias and gain.
³ Method to adjust arbitrary point with application of a voltage (current) between terminals 1
and 5 (4 and 5). Refer to page 5-423.
· Method to adjust arbitrary point without application of a voltage (current) between terminals
1 and 5 (4 and 5). Refer to page 5-424.
» Method to adjust only torque without adjusting voltage (current). Refer to page 5-425.
NOTE Always calibrate the input after changing the voltage/input signal with Pr. 73, Pr. 267, and the volt-
age/current input selection switch.
Analog input display unit changing (Pr. 241)
● The analog input display unit (%/V/mA) for analog input bias and gain calibration can be changed.
● Depending on the terminal input specification set to Pr. 73 and Pr. 267, the display units of C17
(Pr. 919), C19 (Pr. 920), C39 (Pr. 932), and C41 (Pr. 933) will change as shown below.
