Termination resistor
The use of bus termination resistors (120 Ω between CAN_L and CAN_H), one at each end of the bus, is
essential for correct operation of the CAN bus. Even with only one Nix connected, mount the termination
resistor to ensure CAN bus operation.
Do not use wirewound resistors
, which are inductive.
Nix Servo Drive includes a termination resistor on board
. A jumper placed next to the CAN connector
allows the user to connect or disconnect the 120 Ω termination resistor. Use a standard 1.27 mm pitch
jumper for this purpose.
CAN GND connection
GND line in CAN devices is used for equaling potential between master and slaves, but is not used for data
transmission, as the line is fully differential. For this reason, if the
host device shares supply GND with Nix
it is not needed to connect CAN connector GND again
, as this could cause ground loop issues.
