Image 6-12 Telegrams 353 ... 999 for cyclic communication
Abbreviation Explanation
STW1 ... STW3 Control word 1 ... control word 3
ZSW1 ... STW3 Status word 1 ... status word 3
NSOLL_A Speed setpoint 16-bit
NSOLL_B Speed setpoint 32-bit
NIST_A Actual speed value 16-bit
NIST_B Actual speed value 32-bit
IAIST Actual current value

Interconnection of the process data
The telegrams use - with the exception of telegram 999 (free interconnection) - the word-by-
word transfer of send and receive data (r2050/p2051).
If you require an individual telegram for your application (e.g. for transferring double words),
you can adjust one of the predefined telegrams via parameters p0922 and p2079. For
details, please refer to the List Manual, function diagrams 2420 and 2472.
