Rockwell Automation Publication D2-3518-3 - May 2013 115
Chapter 9
Enables a feature to save the present frequency reference value issued by the OIM
to drive memory on power loss. Value is restored to the OIM on power up. HIM
stands for Human Interface Module. It is another way of referring to the OIM.
Figure 43 - Save OIM Ref (192)
Enables/disables a feature to automatically load the present auto frequency
reference value into the OIM when Manual is selected. Allows smooth speed
transition from Auto to Manual.
HIM stands for Human Interface Module. It is another way of referring to the
OIM.
Unipolar = Drive receives unsigned reference (0...32767) and
direction command separately (from the DPI port). For
example, the direction keys on an OIM apply the
direction to the reference.
Bipolar = Drive receives signed reference (-32767...32767). In this
case, the direction keys have no effect.
Reverse Disable = Drive receives signed reference (-32767...32767);
however, regardless of the reference, the drive is not
permitted to reverse.
