®
B
To control the frequency inverter via PROFINET, you must switch the drive inverter to
control signal source (P101) and setpoint source (P100) = SBus beforehand. The SBus
setting means the inverter parameters are set for control and setpoint entry via gateway.
The MOVITRAC
®
frequency inverter then responds to the process output data transmit-
ted from the master programmable controller.
It is necessary to set the SBus1 timeout interval (P815) to a value other than 0 ms for
the MOVITRAC
®
frequency inverter to stop if faulty SBus communication is encoun-
tered. We recommend a value in the range 50 to 200 ms.
Activation of the control signal source and setpoint source SBus is signaled to the ma-
chine control using the "SBus mode active" bit in the status word.
For safety reasons, you must also enable the inverter at the terminals for control via the
fieldbus system. Consequently, you must wire and program the terminals in such a way
that the inverter is enabled via the input terminals. The simplest way of enabling the fre-
quency inverter at the terminals is, for example, to connect the DIØ1 (function
CW/STOP) input terminal to a DC +24-V signal and to set the remaining input terminals
to NO FUNCTION.

INFORMATION
• Set the parameter P881 SBus address to values between 1 and 8 in ascending or-
der. 8.
• The SBus address 0 is used by DFE32B gateway and therefore must not be used.
•Set P883 SBus timeout to values between 50 and 200 ms.
