This section will acquaint the user with connecting and using the microstepping
MDrive products. If your MDrive is equipped with a factory mounted encoder,
also refer to Section 1.3: Interfacing an Encoder. Covered in this section are:
L a y o u t a n d I n t e r f a c e G u i d e l i n e s
Logic level cables must not run parallel to power cables. Power cables will
introduce noise into the logic level cables and make your system unreliable.
Logic level cables must be shielded to reduce the chance of EMI induced noise.
The shield needs to be grounded at the signal source to AC ground. The other end
of the shield must not be tied to anything, but allowed to float. This allows the
shield to act as a drain.
Power supply leads to the driver need to be twisted. If more than one driver is to
be connected to the same power supply, run separate power and ground leads
from the supply to each driver.

The following wiring/cabling is recommended for use with the MDrive:
Recommended Wire Size
Logic Wiring ........................................................................................... 22 AWG
Power and Ground ............................. See Appendix A "Recommended Cable
G e n e r a l P r a c t i c e s
The following wire strip length is recommended:
Wire Strip Length ................................................................... 0.250" (6.0 mm)
NOTE: Wire and insulation type are subject to the user's application and environment.
WARNING! DO NOT connect or disconnect power leads when
power is applied! Disconnect the AC power side to power down
the DC power supply. For battery operated systems, connect a
"transient suppressor" across the power switch to prevent arcs
and high voltage spikes.
