The settings to " " and " " [supply voltage corrected (off during deceleration)] mean the same op-
eration as those to "
" and " ", respectively, except during deceleration. These settings prevent overvolt-
age during deceleration, while minimizing decreases in low-speed operating torque due to changes in volt-
age.
