B.1.4
Connection [X5]: pin allocation of the interface RS232
Collision with interface “RS485”.
If the interface “RS232” is used, the interface “RS485” can additionally be active through
configuration. If a cable is used in which the pins “4” and “9” are contacted on both plugs,
this can result in simultaneous access of the interfaces “RS232” and “RS485” to the motor
controller.
–
For communication with the interface “RS232”, use only a cable that corresponds to
the pin allocation “interface RS232”.
