the branch structure also can be used.
⚫Please connect a 120Ω terminal resistor in parallel to each end of the CAN bus for
matching the circuit impedance and ensuring communication stability.
⚫Please be sure to connect the public ends of each node on the CAN bus to prevent
the CAN chip from burning out.
⚫Please use STP (Shielded Twisted Pair), especially in bad environments, and make
sure the shielding layer is fully grounded.
⚫When on-site wiring, pay attention to make the distance between strong current and
weak current, it is recommended for the distance 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.
→Cable Requirements:
Shielded Twisted Pair, and the shielded cable is grounded.
3.2.2. Basic Usage Method
(1) Please follow the above wiring instructions to wiring correctly.
(2) After powered on, please use any one interface among the three interfaces
(ETHERNET, RS232, RS485) to connect to ZDevelop;

ZMC420SCAN Motion Controller Hardware Manual V1.5
(3) Please use the "ADDRESS" and "SETCOM" commands to set and view the protocol
station number and configured parameters, see "ZBasic Programming Manual" for
details.
(4) Please use the "CANIO_ADDRESS" command to set the master's "address" and
"speed" according to the needs, and use the "CANIO_ENABLE" command to enable or
disable the internal CAN master function, or through "ZDevelop/Controller/State the
Controller/Communication Info” to view the CAN status intuitively, and refer to the
“ZBasic Programming Manual” for details.
(5) According to their respectively instructions, correctly set the relevant parameters of
the third-party equipment to match the parameters of each node.
(6) Correctly set the "address" and "speed" of the slave station expansion module
according to the manual of the slave station.
(7) After all the settings are completed, restart the power supply of all stations to
establish communication.
(8) Note that the "speed" settings of each node on the CAN bus must be consistent, and
the "address" settings cannot cause conflicts, otherwise the "ALM" alarm light will be
on, and the communication establishment will fail or the communication will be
disordered.
