Interfaces
The frequency converter has a RS 232 interface as standard (SERVICE X5)
and is optionally equipped with serial interfaces:
■
RS 485 C
■
Profibus DP
■
Ethernet/IP
The TURBO.DRIVE 400 is configured through the parameters according to
the parameter list. Pxxx denotes parameter value xxx.
The PC software "TURBO.DRIVE Server" allows convenient access by the
user to the parameters of the frequency converter.
In the case of BETA units simultaneous operation of the RS 232 interface in
parallel to the RS 485 interface or the Profibus interface is not yet reliably
supported. For this reason only one interface at a time should be connected
to the unit.
