ATTENTION: Removing and replacing the LCD OIM while the
drive is running may cause an abrupt speed change if the LCD OIM
is the selected reference source, but is not the selected control
source. The drive will ramp to the reference level provided by the
OIM at the rate specified in 140 [Accel Time 1], 141 [Accel Time 2],
142 [Decel Time 1] and 143 [Decel Time 2]. Be aware that an
abrupt speed change may occur depending upon the new
reference level and the rate specified in these parameters. Failure
to observe this precaution could result in bodily injury.
