3.1.3 0-3* LCP Custom Readout
It is possible to customize the display elements for various
purposes: *Custom Readout. Value proportional to speed
(Linear, squared or cubed depending on unit selected in
0-30 Custom Readout Unit ) *Display Text. Text string stored in
a parameter.
Custom Readout
The calculated value to be displayed is based on settings in
0-30 Custom Readout Unit , 0-31 Custom Readout Min Value
(linear only), 0-32 Custom Readout Max Value , 4-14 Motor
Speed High Limit [Hz] and actual speed.

Option: Function:
Program a value to be shown in the display
of the LCP. The value has a linear, squared
or cubed relation to speed. This relation
depends on the unit selected (see table
above). The actual calculated value can be

doutUnit] This parameter allows the
choice of the min. value of the
custom defined readout
(occurs at zero speed). It is only
possible to select a value
different to 0 when selecting a
linear unit in
0-30 Custom
Readout Unit . For Quadratic
and Cubic units the minimum
value will be 0.
