The 2 types of reference inputs are combined in the following formula:
Remote reference=X+X*Y/100%.
If relative reference is not used, set parameter 3-18 Relative Scaling Reference Resource to [0] No function and parameter 3-14 Preset
Relative Reference to 0%. The digital inputs on the drive can activate both the catch up/slow down function and the freeze reference
function. The functions and parameters are described in the programming guide.
The scaling of analog references is described in parameter group 6-1* Analog Input 53 and parameter group 6-2* Analog Input 54, and
the scaling of digital pulse references is described in parameter group 5-5* Pulse Input.
Reference limits and ranges are set in parameter group 3-0* Reference Limits.
8.3.2.2 Reference Limits
Parameter 3-00 Reference Range, parameter 3-02 Minimum Reference, and parameter 3-03 Maximum Reference define the allowed
range of the sum of all references. The sum of all references is clamped when necessary. The relation between the resulting reference
(after clamping) and the sum of all references are shown in the following illustrations.
P 3-00 Reference Range = [0] Min-Max
