ZMC306N Motion Controller User Manual V1.5
⚫
Please connect a 120Ω terminal resistor in parallel at the two ends of the CAN bus to
match the circuit impedance and ensure communication stability (when point to
point connection is used or the number of slave stations is not many and the wiring
is short, the terminal resistor can not be used).
⚫
When the number of slave stations is large, please connect a 120Ω terminal resistor
at the two ends of the RS485 cable in parallel to match the circuit impedance and
prevent signal reflection.
⚫ Please be sure to connect the common terminal of each node on the CAN bus to
prevent the CAN chip from burning out.
⚫
The distance between each node branch line on the RS485/CAN bus wiring circuit
should be less than 3m.
⚫
Please use twisted-pair shielded wires, especially in harsh environments, make sure
the shielding layer is fully grounded.
⚫
On-site wiring should also pay attention to the distance between strong current and
weak current wiring, it is recommended to be more than 20cm.
⚫
It should be noted that the equipment grounding (chassis) on the entire line must be
good, and the grounding of the chassis should be connected to the standard factory
ground pile.
