Depending on the setting in p0922, the interface mode of the control and status word is
automatically set:
● p0922 = 1, 352, 999:
STW 1/STW 1: Interface Mode SINAMICS / MICROMASTER, p2038 = 0

b. Manufacturer-specific telegrams
The manufacturer-specific telegrams are structured in accordance with internal company
specifications. The internal process data links are set up automatically in accordance with
the telegram number setting.
The following vendor-specific telegrams can be set via p0922:
•
p0922 = 220 Speed setpoint 32 bit, metal industry
c. Free telegrams (p0922 = 999)
Send and receive telegrams can be configured as required by using BICO technology to
interconnect the send and receive words. The default process data assigned under a) is
retained during the changeover to p0922 = 999, although it can be changed or
supplemented at any time.
To maintain compliance with the PROFIdrive profile, however, the following assignments
should be retained:
● Interconnect PZD receive word 1 as control word 1 (STW 1)
● Interconnect PZD send word 1 as status word 1 (STW 1)
Please refer to function diagrams FP2460 and FP2470 for details on interconnection options.
Telegram interconnections
After changing p0922 = 999 (factory setting) to p0922 ≠ 999, the telegrams are
interconnected and blocked automatically.
Note
Exceptions
Exceptions here are telegrams 20, 220 and 352. In addition to the fixed interconnections,
selected process data (PZD) can be interconnected as required in the send/receive telegram
there.
When you change p0922 ≠ 999 to p0922 = 999, the previous telegram interconnection is
retained and this can be changed.
