Wiring Reference For CAN, Input, Output and Power
ECI1000 series motion control card uses single power. ZIO expansion module uses
double power to supply, in actual application, ZIO power channels on expansion
modules can share the same power supply, the IO power supply of the E24V of
the IO board is powered separately. When the control card and expansion module
use different powers, the GND of card CAN terminal must be connected to the
GND of expansion module’s power, otherwise, CAN bus may be burned out.
When multi expansion modules are linked on CAN bus, it is necessary to connect
120Ω resistor between CANL and the CANH on the last IO expansion module.
