Ensure that:
1. The shield screw is grounded as close to the
MC4N as possible.
2. 0V connection is NOT used for terminating
screens.
3. Pin 5 of Encoder/Stepper plug is connected
to 0V on drive.
4. Encoder cable screen is clamped to 9 way D
shell.
5. The MC4N 24V supply has common 0V with
the drive(s).
When wiring MC4N Stepper output to a
differential input stepper drive, use the 0V
and shield connections shown for the encoder.
The stepper drive must have its common 0V
connected to the MC4N.
