3.2.4 0-3* LCP Custom Readout
It is possible to customise the display elements for various
purposes:
•
Custom Readout. Value proportional to speed
(linear, squared or cubed depending on unit
selected in
parameter 0-30 Custom Readout Unit ).
•
Display Text. Text string stored in a parameter.
Custom readout
The calculated value to be displayed is based on the
settings in:
•
Parameter 0-30 Custom Readout Unit .
•
Parameter 0-31 Custom Readout Min Value (linear
only).
•
Parameter 0-32 Custom Readout Max Value .
•
Parameter 4-13 Motor Speed High Limit [RPM] .
•
Parameter 4-14 Motor Speed High Limit [Hz]
•
Actual speed.

Option: Function:
Programme a value to be shown in the LCP
display. The value has a linear, squared or cubed
relation to speed. This relation depends on the
unit selected (see
Table 3.3 ). The actual calculated
value can be read in parameter 16-09 Custom
Readout , and/or shown in the display by selecting
[1609 Custom Readout] in parameter 0-20 Display
