VLT AutomationDrive FC 301/302
Programming Guide
Enter the increment size required for increase/decrease as a percentage of the synchronous motor speed, n
activated, the resulting reference is increased or decreased by the value set in this parameter.
Parameter 3-91 Ramp Time
Table 257: Parameter 3-91 Ramp Time
3-91 Ramp Time
Default value: 0 s
Conversion index: -2
Enter the ramp time, that is the time for adjustment of the reference 0–100% of the specified digital potentiometer function (in-
crease, decrease, or clear). If increase/decrease is activated for longer than the ramp delay period specified in parameter 3-95 Ramp
Delay, the actual reference is 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 parameter 3-90 Step Size.
Parameter 3-92 Power Restore
Table 258: Parameter 3-92 Power Restore
3-92 Power Restore
Default value: [0] Off
Conversion index: –
Option Name Description
[0]* Off Resets the digital potentiometer reference to 0% after power-up.
[1] On Restores the most recent digital potentiometer reference at power-up.
Parameter 3-93 Maximum Limit
Table 259: Parameter 3-93 Maximum Limit
3-93 Maximum Limit
Default value: 100%
Conversion index: 0
Set the maximum allowed value for the resulting reference. This is recommended if the digital potentiometer is used for fine-tuning
of the resulting reference.
Parameter 3-94 Minimum Limit
Table 260: Parameter 3-94 Minimum Limit
3-94 Minimum Limit
Default value: 100%
Conversion index: 0
Set the minimum allowed value for the resulting reference. This is recommended if the digital potentiometer is used for fine-tuning
of the resulting reference.
Parameter 3-95 Ramp Delay
