Source selection (see Terms and abbreviations
Adjusts the gain of the speed correction term in a speed-
controlled follower. In effect, defines how accurately the
follower follows the master torque. A greater value results in a
more accurate performance.
See section Load share function with a speed-controlled
follower (page 32).
Speed correction term adjustment.
Selects the source of the torque reference for the load share
function. See section Load share function with a speed-
controlled follower (page 32).
None.
