0-30 Custom Readout Unit
Option: Function:
Program a value to be shown in the
display of the keypad. The value has a
linear, squared, or cubed relation to speed.
This relation depends on the unit selected
(see Table 3.1). The actual calculated value
can be read in parameter 16-09 Custom
Readout.

This parameter sets the
minimum value of the custom-
dened
readout (occurs at 0
speed). It is only possible to
select a value dierent from 0
when selecting a linear unit in
parameter 0-30 Custom Readout
Unit. For quadratic and cubic
units, the minimum value is 0.
