9 RS485 Communication

9.1 Communication method

Communication between users and the drive software takes place via so-called telegrams. Each program contains specified data, which has
to be received or sent. The drive software ignores telegrams that are not addressed to it.

RS485 communication is possible with the following parameterisation:
Baud rate = 115200
Number of data bits: 8
Number of stop bits: 1
Parity: even

9.2 Cycle time

The telegrams “COM_CRX_FAHRBEFEHL_DREHZAHL” and “COM_CRX_FAHRBEFEHL_POSITION” may only be sent every 10 ms maximum, as
otherwise working through the telegrams uses up too much computing time.
If the telegrams are sent faster (< 10 ms) information is lost. The command is incomplete and is not executed. This does not cause any
damage to the drive.
