Parameter Descriptions
Decrease or Clear. To activate the function, at least one
digital input must be set up to Increase or Decrease.

Range:
0.10 % [0.01 - 200.00 %]

3-91 Ramp Time

Range: Function:
1.00 [0.00 - Enter the ramp time, i.e., the time for
s 3600.00 s] 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
3-95 Ramp Delay, the actual reference will be
ramped 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 3-90 Step Size.

3-92 Power Restore

Option: Function:
[0] Off Resets the Digital Potentiometer reference to 0% after
*
power-up.
[1] On Restores the most recent Digital Potentiometer
reference at power-up.
