Reference Mode rEF
Use the reference mode to monitor and if local control is enabled (
AIU1
) adjust the actual
reference value by rotating the jog dial.
When local control is enabled, the jog dial on the HMI acts as a potentiometer to change the reference value up and down within the limits
preset by other parameters (LSP or HSP). There is no need to press the ENT key to confirm the change of the reference.
If local command mode is disabled, using
When local control is enabled, the jog dial on the HMI acts as a potentiometer to change the reference value up and down within the limits

If local command mode is disabled, using

, only reference values and units are displayed. The value
will be "read only" and cannot be modified by the jog dial (the reference is no longer given by the jog dial but from an AI or other source).
The actual reference displayed depends on the choice made in
