F-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.
F-91 Accel/Decel 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. F-95 Accel/Decel
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. F-90 Step Size.
F-92 Power Restore
Option: Function:
[0] * Off Resets the Digital Pot-Meter reference to 0% after power up.
[1] On Restores the most recent Digital Pot-Meter reference at power up.
F-93 Maximum Limit
Range: Function:
100 %* [-200 - 200 %] Set the maximum permissible value for the resultant reference. This is advisable if the Digital Pot-Meter
is used for fine tuning of the resulting reference.
F-94 Minimum Limit
Range: Function:
-100 %* [-200 - 200 %] Set the minimum permissible value for the resultant reference. This is advisable if the Digital Pot-Meter is
used for fine tuning of the resulting reference.
F-95 Accel/Decel Ramp Delay
Range: Function:
0* [0 - 0] Enter the delay required from activation of the digital pot-meter 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. F-91 Accel/Decel Time.
