3.4.1 3-0* Reference Limits
Parameters for setting the reference unit, limits, and
ranges.
Also see parameter group 20-0* Feedback for information on
settings in closed loop.
3-02 Minimum Reference
Range: Function:
0* [-4999–4999] The minimum reference is the lowest value
obtainable by summing all references.

Enter up to 8 dierent preset references (0–7)
in this parameter, using array programming. For
selecting dedicated references, select preset
reference bit 0/1/2 [16], [17], or [18] for the
