Configuring the MOVITRAC
®
B frequency inverter
To control the MOVITRAC
®
B frequency inverter via DeviceNet, you must switch the
drive inverter to
control signal source (P101)
and
setpoint source (P100)
= SBus be-
forehand. The SBus setting means the MOVITRAC
®
B parameters are set for control
and setpoint entry via gateway. The MOVITRAC
®
B then responds to the process output
data transmitted by the PLC.
It is necessary to set the SBus1 timeout interval (P883) to a value other than 0 ms for
the MOVITRAC
®
B inverter to stop if faulty SBus communication is encountered. We
recommend a value in the range 50 ... 200 ms. Activation of the control signal source
and setpoint source SBus is signaled to the higher-level controller using the "SBus mode
active" bit in the status word.
For safety reasons, you must also enable the MOVITRAC
®
B at the terminals for control
via the fieldbus system. Therefore, you must wire and program the terminals in such a
way that the MOVITRAC
®
B is enabled via the input terminals. The simplest way of en-
abling the MOVITRAC
®
B at the terminals is, for example, to connect the DIØ1 (function
CW/STOP) input terminal to a +24-V signal and to program the remaining input termi-
nals to NO FUNCTION.

NOTE
Set the parameter
P881 SBus address
to values between 1 to 8 in ascending order 8.
A MOVITRAC
®
B with integrated DFD11B has the SBus address 1 as factory setting
(as of firmware .15).
The SBus address 0 is used by the DFD11B gateway and must therefore not be used.
Set
P883 SBus timeout
to values between 50 ... 200 ms
