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 par. 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 par. 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.
3-93 Maximum Limit
Range: Function:
100 %* [-200 - 200 %] Set the maximum permissible value for the resultant reference. This is advisable if the Digital Po-
tentiometer 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 resultant reference. This is advisable if the Digital Po-
tentiometer is used for fine tuning of the resulting reference.
3-95 Ramp Delay
Range: Function:
Application
dependent*
[Application dependant] 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
Ramp Time
.
