Appendix B

Removing the OIM While the Drive is Powered

If the OIM is the selected control source, removing the OIM while the drive is
powered will cause a drive fault.

If the 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.

If the LCD OIM is not the selected control source or reference source, removing
the OIM while the drive is powered will have no effect on drive operation.

Display Description

This section describes the display features and the key functions.

Figure 94 - The Display (Main Menu Shown)

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.
