3-90 Step Size
Range:
Function:
0.10 %
*
[0.01 -
200.00 %]
Enter the increment size required for
INCREASE/DECREASE, as a percentage of
the synchronous motor speed, n
s
. If
INCREASE/ DECREASE is activated the
resulting reference will be increased /
decreased by the amount set in this
parameter.
3-91 Ramp Time
Range:
Function:
1.00 s [0.00 -
3600.00 s]
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
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
.
3-92 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.
3-93 Maximum Limit
Range:
Function:
100 %
*
[-200 - 200
%]
Set the maximum permissible value for
the resultant reference. This is advisable if
the Digital Potentiometer is used for fine
tuning of the resulting reference.
3-94 Minimum Limit
Range:
Function:
0 %
*
[-200 - 200
%]
Set the minimum permissible value for the
resultant reference. This is advisable if the
Digital Potentiometer is used for fine
tuning of the resulting reference.
3-95 Ramp Delay
Range:
Function:
Size
related
*
[ 0.000 -
0.000 ]
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.
