Ensure that:
1. The shield screw is grounded

as close to the MC405 as
possible.

2. 0V, V- and E- connections are

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 MC405 24V supply has

common 0V with the drive(s).

When wiring MC405 Stepper
outputs 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 MC405
24V return. (24V -)
