4.4.8 3-9* Digital Potentiometer
The digital potentiometer enables increase or decrease of
the actual reference by adjusting the set-up of the digital
inputs using the functions
Increase
,
Decrease
or
Clear
. To
activate the function, at least 1 digital input must be set to
Increase
or
Decrease
.
3-90 Step Size
Range:
Function:
0.10 %
*
[0.01 -
200 %]
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 is increased/ decreased by the
amount set in this parameter.
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
resulting reference. This is recommended if
the digital potentiometer is used for fine-
tuning of the resulting reference.
3-94 Minimum Limit
Range:
Function:
-100 % [-200 -
200 %]
Set the minimum permissible value for the
resulting reference. This is recommended if
the digital potentiometer is used for fine-
tuning of the resulting reference.
3-95 Ramp Delay
Range:
Function:
1000
ms
*
[0 -
3600000 ms]
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.
