
PROFINET Overview
This section describes the communication profile used between the PROFINET I/O network and the option.
The option supports the PROFIdrive profile. Users can select between the control and status words according to the
PROFIdrive profile or use the Yaskawa-specific control and status words.

PROFIdrive Communication Profile

The Control Word and the Status Word
The contents of the Control Word and the Status Word are detailed in Table 9 . and Table 10 . respectively. The drive states
are presented in the PROFIdrive State Machine ( Figure 18 .).

Frequency Reference
The Frequency reference is a 16-bit word containing a sign bit and a 15-bit integer. A negative reference (indicating
reverse direction of rotation) is formed by calculating the two's complement from the corresponding positive reference.
The reference value is the desired output frequency.

Output Frequency
Output Frequency is a 16-bit word containing the current output frequency (U1-02) of the drive.
