Chapter 9 Parameter Descriptions
Determines the bandwidth around a skip frequency (half the band above and half
the band below the skip frequency).
Selects the source of the speed reference to the drive unless Preset Speed 1...7
(101...107)
is selected.
Note that the manual reference command can override the reference control
source.

ATTENTION: Removing and replacing the OIM while the drive is running may
cause an abrupt speed change if the OIM is the selected reference source. The
drive will ramp to the reference level provided by the OIM at the rate specified in
Accel Time 1 (140), Accel Time 2 (141), Decel Time 1 (142), and Decel Time 2
(143). 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.
