CAN
The structure of the C
is to be realised so as to guarantee that a 120 ohm terminating
resisto is provided o
s. On the drive module itself exists a terminating resistor. It is
activa
by the DIP sw
N terminator. The stub lines leading from the bus to the individual
modu
should not be l
n 50 cm in case of a baud rate of 1 Mbit/s.

For the CAN wiring, it is recommended to use twisted shielded cables with a characteristic
impedance of 108 to 132 ohms. In case of very small network extensions, it may be possible to
dispense with the connection of the reference potential (CAN ground) (not recommended).
