If an acyclical request cannot be executed by the converter, it replies with one of the
following error messages.
Error message
7.7.4.1

Cyclic communication

Converter → master
The converter cyclically transfers the data from p2051[1] and p2051[2] in four bytes to the
master. You can process these four bytes in the control as for analog data. Refer to the
documentation for the AS-i master for detailed information about access to analog data.
If you selected Macro 31 or 34 during the commissioning, the two indexes are
interconnected as follows:
• p2051[1] = 63: Smoothed actual speed value
• p2051[2] = 27: Absolute smoothed actual current value
The values for transfer are normalized in accordance with the PROFIdrive N2 data type.
Using p2051[1] and p2051[2] you can interconnect any other or connector parameters and
transfer to the control.
