Connection example 1
Stepper drives.
All outputs are RS422
differential line drivers rated
at 5V 10mA.
The 0V may be omitted if the
stepper drive inputs are fully
opt0-isolated.
Connection example 2
Servo drives with 24V enable
Many Servo drives that have pulse and direction inputs for motion also use a 24V enable
input. The WDOG connection, pins 6 and 14 on the Auxiliary connector can be used to
directly enable the drives. The same signal can be used to enable all 4 axes.
A risk assessment must be done to decide if any of the motors that are controlled by
the MC404-Z might cause harm to an operator. The MC404-Z WDOG and Enable outputs
are NOT Safety outputs. An additional safety circuit may be needed to comply with
regulations.
