RS232 interface (diagnosis/parameterization interface)
The RS232 interface is intended as a configuration interface.
Parameters
Signal level
In accordance with RS232 specification or RS-485 specification
Baud rate
9600 baud to 115 kBaud
ESD protection
ESD protected (16 kV) driver
Connection
Null modem standard, X5
Connection
Over X5 / DSUB 9 pin / pin
Tab. 3.5: Parameters of the RS232 interface
The RS-485 interface is on the same plug connector as the RS232 interface.
Communication must be activated separately by the user. RS232 messages can also be
received when RS-485 communication is activated, which means that the device can be
accessed for configuration at all times.
After reset, the serial interface always has the following basic settings.
Parameters
Value
Baud rate
9600 baud
Data bits
8
Parity
None
Stop bits
1
Tab. 3.6: Default parameters
To be able to operate an interface with a terminal program, such as for test purposes, the

Tab. 3.7: Setting for terminal program
Please note that, immediately after a reset, the motor controller independently issues a
bootup message via the serial interface. A reception program on the controller must either
process or reject these received characters.
