9.5.5 PROFIdrive Profile
For optimal interoperability, the interface card supports the PROFIdrive profile version 4.1. Use of the
PROFIdrive profile is optional and is not recommended unless specifically required in the PROFINET
system specification. No explicit configuration of the interface card is necessary in the studio when using
the PROFIdrive profile. The controller must support the PROFIdrive profile and must be c onfigured to
use the “Standard Telegram 1” module on the interface card. If the controller does not support the
PROFIdrive profile, use the configurable I/O “IN: 32 WORDS, OUT: 32 WORDS” module. The
PROFIdrive profile is only partially described in this manual due to its complexity. The c omplete
PROFIdrive profile specifications can be obtained from http://www.profibus.com/
.
Some other notes of interest include:
• Implements Application Class 1 (standard drive)
• Supports only Standard Telegram 1 (ST1, PZD-2/2) on slot 1 (similar to Profibus PPO type 3)
• Supports only Speed Control Mode

9.5.5.2 PROFIdrive Control and Status Words
The control word, STW1, is the principal means for controlling the drive. It is sent by the controller (PLC)
to the device (inverter). The bitmapping for the control word is described in Table 39. The status word,
ZSW1, returns status information from the inverter to the controller. The bitmapping for the status word
is described in Table 40.
