Fig. 6-192: Signal adjustment of terminal 4
There are the following three methods to adjust the torque setting voltage (current) bias and
gain.
● Method to adjust any point without application of voltage (current) to across terminals 1-5
(4-5). (Refer to page 6-397)
● Method to adjust any point without application of voltage (current) to across terminals 1-5
(4-5). (Refer to page 6-398)
● Method to adjust torque only without adjustment of voltage (current). (Refer to page 6-399).
NOTE
When voltage/current input specifications were switched using Pr. 73 and Pr. 267, perform
calibration without fail.
