Select Linked to Hand / Auto [0] to use the local
reference when in Hand mode; or the remote
reference when in Auto mode.
Select Remote [1] to use the remote reference
in both Hand mode and Auto mode.
Select Local [2] to use the local reference in
both Hand mode and Auto mode.
3-14 Preset Relative Reference
Range:
-100.00 - 100.00%
Function:
Define a fixed value (in %) to be added to the
variable value (defined in par. 3-18 Relative Scaling
Reference Source). The sum of the fixed and
variable values (labeled Y in the illustration below)
is multiplied with the actual reference (labeled
X in the illustration below). This product is then
added to the actual reference (X+X*Y/100) to
give the resulting actual reference.

Analog input 53
Analog input 54
Frequency input 29
Frequency input 33
Local bus reference
Digital pot.meter
Function:
Select the reference input to be used for the first
reference signal. Par. 3-15, 3-16 and 3-17 define
up to three different reference signals. The sum of
these reference signals defines the actual reference.
This parameter cannot be adjusted while
the motor is running.
