FUNCTION COMPATIBILITY
The table below shows the I/O functions that are not compatible with each other. Any function not listed
in this table is compatible with all other functions.
Aside from the particular functions shown in this table, two general priorities exist:
• Stop functions always have priority over Run commands.
• Speed references via logic command always have priority over analog setpoints.
In addition, the choice of functions is limited by:
• The number of controller inputs and outputs to be re-assigned.
• The incompatibility of certain functions with others.

Function priority (functions which cannot be active at the same time):
The arrow points to the function that has priority.
The stop functions have priority over run commands.
The speed references from a logic command have priority over analog references.
Note: An incompatible function must be deselected before the desired function can be programmed.
For example, if preset speeds is programmed, it must be cleared before the +/- speed parameter
can be selected.
