Parameter Frequency/torque setting by analog input (terminals 1, 2 and 4)
FR-A700 EC 6 - 395
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).
