SECTION 2.3
Interfacing and Using the MDrivePlus Motion Control I/O
The MDrivePlus Motion Control Digital I/O
The MDrivePlus Motion Control product line is available with two digital I/O configurations, Standard and Enhanced.
The digital I/O may be defined as either active HIGH or active LOW. When the I/O is configured as active HIGH,
the level is +5 to +24 VDC and the state will be read/set as a “1”. If the level is 0 VDC, then the state will be read/set
as “0”. Inversely, if configured as active LOW, then the state of the I/O will be read/set as a “1” when the level is LOW,
and “0” when the level is HIGH. The active HIGH/LOW state is configured by the third parameter of the I/O Setup
(S1-4, S9-12) variable. The goal of this I/O configuration scheme is to maximize compatibility between the MDrivePlus
Motion Control and standard sensors and switches.

Standard I/O Set
The MDrivePlus Motion Control comes standard with a set
of four I/O — (4) sinking or sourcing 0 to +24 VDC inputs
or (4) sinking 0 to +24 VDC outputs, which may be pro-
grammed individually as either general purpose or dedicated
inputs or outputs, or collectively as a group.
Enhanced I/O Set - MDrive34Plus2
The MDrivePlus2 Motion Control is equipped with a set of
eight I/O — (8) sinking or sourcing 0 to +24 VDC inputs
or (8) sinking or so12 to +24 VDC outputs, which
may be programmed individually as either general purpose
or dedicated inputs or outputs, or collectively as a group.
The eight I/O consist of two separate banks of four points:
Bank 1: IO1 - IO4, Bank 2: IO9 - IO12.
Uses of the Digital I/O
The I/O may be utilized to receive input from external devices such as sensors, switches or PLC outputs. When con-
figured as outputs, devices such as relays, solenoids, LEDs and PLC inputs may be controlled from the MDrivePlus
NOTE: On
the Standard
MDrivePlus,
when configured as
outputs, the I/O set
is sinking ONLY! The
Plus2 Models add the
functionality of I/O
Power, which enables
the user to use all the
outputs, both
Standard and
Enhanced, as
Sinking or Sourcing.
NOTE: If the unit
purchased has the
remote encoder option,
the additional points
become dedicated to
encoder functions!
