Introduction to PROFIBUS

Section 1-3

1-3-3

What is PROFIdrive

The PROFIdrive device profile supplements the PROFIBUS standard. It
defines a unified behavior and technique to access Inverter and drive device
data. All drives supporting the PROFIdrive profile respond the same way to
control instructions.

!Caution

For backward compatibility and direct use of the Inverter registers, the Option
Board offers two additional device profiles that are NOT PROFIdrive compli-
ant. For PROFIdrive compliance, ensure that P182 = 0.
