5000 FLUX

If Relative [1] is selected, one of the adjusted

preset references (parameters 215-218) is added

to the external references as a percentage

of the actual reference.

If External/preset [2] is selected, it is possible to shift

between external references or preset references

via terminal 16, 17, 29, 32 or 33 (parameter 300,

301, 305, 306 or 307). Preset references will be a

percentage value of the reference range.

External reference is the sum of the analogue

references, pulses and bus references. See also

section Reference Handling.

NB!:

If Sum or Relative is selected, one of the

preset references will always be active. If the

preset references are to be without influence,

they must be set to 0 % (factory setting).

The example shows how to calculate the output

speed by using Preset references together with

Sum and Relative in parameter 214.

Parameter 205 Maximum reference has been

set to 1500 rpm.
