2.1 Installing and Removing the LCD OIM
A cable (RECBL-LCD) must be used to convert the OIM for hand-held use. The
maximum cable length is 32 feet using extender cables.
To install the LCD OIM, connect the OIM to DPI port 3 on the DPI Communication
Interface board until it clicks into place.
To remove the LCD OIM, pull back on the OIM cable connector to release the OIM
from the DPI Communication Interface board.
2.1.1 Removing the LCD OIM While the Drive is Powered
If the LCD OIM is the selected control source, removing the OIM while the drive is
powered will cause a drive fault.
If the LCD OIM is not the selected control source, but is the reference source,
removing the OIM while the drive is powered will result in a zero reference value.
When the OIM is replaced, the drive will ramp to the reference level supplied by the
OIM.

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 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.
