If INCREAS E / DECREASE is activated for longer
than the ramp delay period specified in par. 3-95,
the actual referen ce will be ramped up / down
accordingtothisramptime. Theramptimeis
defined as the time used to adjust the reference by
thestepsizespecifiedinpar. 3-90Step Size.
3-92 Power Restore
Option:
*
Off [0]
On [1]
Function:
Select Off [0] to reset the Digital Potentiometer

Range:
-200 - 200 %
*
100%
Function:
Set the maximum permissible value for the
resultant refe rence. This is advis able if the
digital potentiometer is use d for fine tuning
of the resulting reference.
3-94 Minimu m Limit
Range:
-200 - 200 %
*
-100%
Function:
Set the minimum permissible value for the
resultant refe rence. This is advis able if the
Digital Potentiometer is used for fine tuning
of the resulting reference.
3-95 Ramp Delay
Range:
0.000 - 3600.00 s
*
1.000s
Function:
Enter the delay required from activation of the
