Inputs 0 to 7 can be used as registration inputs allocated by REG_INPUTS for axis 3, using the
REGIST command.
Auxiliary connector
The 15 way D-Type connector is a multi-function socket that has 1 x RS232 port, 1 x
RS422/RS485 port, 1 x CANbus port, Anlogue I/O and connections for the WDOG solid-state
relay.
Grounding and Shielding
Good quality screened cables should be used for the auxiliary port. The serial ports and
CANbus port are not galvanically isolated, therefore the 0V return MUST be connected to all
peripheral devices. In addition, bond together the 0V (24V return) terminals of all system
components to minimise current flowing in the serial cables.
Ensure that:
1.
0V connection is NOT used for terminating screens.
2.
For fully opto-isolated inputs on the drive, the 0V may be ommitted.
3.
Screen should be connected to the 9 or 15 way D-type shell.
4.
The MC404-Z 24V supply has common 0V with the drive(s).
