MDrive34Plus Motion Control Product Introduction
Introduction to the MDrive34Plus Motion Control System
The MDrive34Plus Motion Control offers system designers
a low cost, intelligent motion controller integrated with a
NEMA 34 high torque brushless motor and a +12 to +75
volt microstepping driver.
The unsurpassed smoothness and performance delivered by
the MDrive34Plus Motion Control are achieved through
IMS's advanced 2nd generation current control. By apply-
ing innovative techniques to control current flow through
the motor, resonance is significantly dampened over the
entire speed range and audible noise is reduced.
The MDrive34Plus accepts a broad input voltage range
from +12 to +75 VDC, delivering enhanced performance
and speed. Oversized input capacitors are used to minimize
power line surges, reducing problems that can occur with
long runs and multiple drive systems. An extended operat-
ing range of –40° to +85°C provides long life, trouble free service in demanding environments.
Standard features available in the MDrive34Plus Motion Control include four +5 to +24 volt general purpose I/O
lines, one 10 bit analog input, 0 to 5MHz step clock rate, 20 microstep resolutions up to 51,200 steps per revo-
lution, and full featured easy-to-program instruction set.
Expanded features in the MDrive34Plus2 version include eight
+5 to +24 volt general purpose I/O lines and the capability of
electronic gearing by following a rotary or linear axis at an elec-
tronically controlled ratio, or an output clock can be generated
fixed to the internal step clock.
All MDrive34Plus Motion Control are available with optional
closed loop control. This increases functionality by adding stall
detection, position maintenance and find index mark.
The closed loop configuration is added via a 512 line (2048
edge) magnetic encoder with index mark, internal to the unit
so there is no increase in length. Or, for an expanded choice of
line counts and resolutions with MDrive34Plus2 versions only,
closed loop control is available with an interface to a remotely
mounted user-supplied external encoder.
The MDrive communicates over RS-422/485 which allows for
point-to-point or multiple unit configurations utilizing one communication port. Addressing and hardware support
up to 62 uniquely addressed units communicating over a single line. Baud rate is selectable from 4.8 to 115.2kbps.
Available motor configurations include a single shaft rotary motor and a linear actuator with long life Acme screw*.
Rotary versions are available in three motor lengths. Interface connections are accomplished using 12.0” (30.5cm)
flying leads, or with pluggable locking wire crimp connectors for Plus2 versions only.
The MDrive34Plus is a compact, powerful and inexpensive solution that will reduce system cost, design and assem-
bly time for a large range of brushless motor applications.
