Functions and allocations of individual interfaces
X2: Serial interface
The serial interface serves for the communication between the drive
controller and a PC. It is needed for programming, parameterization and
diagnosis during commissioning and service. For this purpose the
appropriate software (e. g. SERCTOP or DriveTop) needs to be installed
on the PC.
It can be operated as RS-232 or, from device index A12 onwards, as
RS-485.
Note:
For details on how to install interface leads please see the
documentation on "Electromagnetic Compatibility (EMC) in
Drive and Control Systems".
RS-232 interface
The RS-232 interface enables:
•
a maximum number of participants of 1, i. e. , when using DriveTop,
only one drive can be parameterized via the RS-232 interface,
•
a transmission length of up to 15 meters and
•
transmission rates of 9600/19200 baud.
