Parameter Group 4-** Limits/Warnings; Motor Limits - Danfoss VLT AutomationDrive FC 301 Programming Manual

Programming Guide | VLT® AutomationDrive FC 301/FC 302
3-91 Ramp Time
Default value: 1 s
Setup: All setups
Data type: Uint32
Enter the ramp time, that is the time for adjustment of the reference 0–100% of the specified digital potentiometer function (increase,
decrease, or clear). If increase/decrease is activated for longer than the ramp delay period specified in 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.
3-92 Power Restore
Default value:
[0] Off
Setup: All setups
Data type:
Uint8
Option Name
[0]* Off
[1] On
3-93 Maximum Limit
Default value: 100%
Setup: All setups
Data type: Int16
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.
3-95 Ramp Delay
Default value: Size related
Setup:
All setups
Data type: TimeD
Enter the delay required from activation of the digital potentiometer function until the drive starts to ramp the reference. With a delay of
0 ms, the reference starts to ramp when increase/decrease is activated. See also parameter 3-91 Ramp Time.

Parameter Group 4-** Limits/Warnings

6.6.1

4-1* Motor Limits

Define torque, current, and speed limits for the motor, and the reaction of the drive when the limits are exceeded. A limit may generate
a message in the display. A warning always generates a message in the display or in the fieldbus. A monitoring function may initiate a
warning or a trip after which the drive stops and generates an alarm message.
