TR200 Programming Guide
Function:
Enter the ramp time, i.e. the time for adjustment of the reference from
0% to 100% of the specified digital potentiometer function (INCREASE,
DECREASE or CLEAR).
If INCREASE / DECREASE is activated for longer than the ramp delay
period specified in par.3-95
ped up / down according to this ramp time. The ramp time is defined as
the time used to adjust the reference by the step size specified in par.
3-90 Step Size.
Function:
Resets the Digital Potentiometer reference to 0% after power up.
Restores the most recent Digital Potentiometer reference at power up.
Function:
Set the maximum permissible value for the resultant reference. This is
advisable if the Digital Potentiometer is used for fine tuning of the re-
sulting reference.
Function:
Set the minimum permissible value for the resultant reference. This is
advisable if the Digital Potentiometer is used for fine tuning of the re-
sulting reference.
Function:
Enter the delay required from activation of the digital potentiometer
function until the frequency converter starts to ramp the reference. With
a delay of 0 ms, the reference starts to ramp as soon as INCREASE /
DECREASE is activated. See also par.3-91
