GE AF-60 LP - Parameter Group 3: Reference;Ramps

4.4. Parameter Group 3: Reference/Ramps
4.4.1. 3-** Reference/Ramps
Parameters for reference handling, definition of limitations, and configuration of the frequency converter's reaction to changes
4.4.2. 3-0* Reference Limits
Parameters for setting the reference unit, limits and ranges.
3-00 Reference Range
Option: Function:
Select the range of reference and feedback signals. Values can be both positive and negative, unless par. 1-00,
Configuration Mode, is set to Process Closed Loop [3]. In that case only positive values are allowed.
[0]
*
Min - Max Reference setpoint ranges can have positive values only.
Select this if running in Process Closed Loop.
[1] -Max - +Max Ranges can have both positive and negative values.
3-02 Minimum Reference
Range: Function:
0.00 * [-4999 - 4999]
Enter value for minimum reference.
The sum of all internal and external references are clamped (limited) to the minimum reference value, par. 3-02.
3-03 Maximum Reference
Range: Function:
Maximum Reference is adjustable in the range Minimum Reference - 4999.
50.00
* [-4999 - 4999]
Enter value for Maximum Reference.
The sum of all internal and external references are clamped (limited) to the maximum reference value, par. 3-03.
4.4.3. 3-1* References
Parameters for setting up the reference sources. Select the preset references for the corresponding digital inputs in parameter group 5.1*, Digital Inputs.
3-10 * Preset Reference
