This section will acquaint the user with connecting and using MDrive17 and
MDrive23 C Connector Versions which have a 12 Position, Keyed and Locking
Pin and Receptacle. If your MDrive17/23 is equipped with a factory mounted
encoder, also refer to Section 1.3: Interfacing an Encoder. Covered in this
section are:
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 MDrive need to be twisted. If more than one MDrive
is to be connected to the same power supply, run separate power and ground leads
from the supply to each driver.

MDrive17 and MDrive23 C Connector Versions utilize a 12 Position, Keyed and
Locking Pin and Receptacle for interfacing the I/O. For quick connection and
setup, the following cables are available from IMS.
P a r a m e t e r S e t u p C a b l e
A low cost accessory which eliminates the need for the user to wire communica-
tions. Included in this cable is built-in logic level shifting circuitry to accommo-
date the 3.3v ports on some PCs.
Order Cable Part No. MD-CC100-000 plus Adapter Cable Part No. MD-ADP-
1723C to connect the MDrive C Connector to a standard DB-25 PC Parallel/SPI
port.
P r o t o t y p e D e v e l o p m e n t C a b l e
To expedite interfacing to MDrive17 and MDrive23 with C Connector. Order
Cable Part No. ADP-3512-FL.
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.
