MDrive23Plus Motion Control Product Introduction

Introduction to the MDrive23Plus Motion Control System

The MDrive23Plus Motion Control offers system designers a low
cost, intelligent motion controller integrated with a NEMA 23
high torque brushless motor and a +12 to +75 volt microstepping
driver.
The unsurpassed smoothness and performance delivered by the
MDrive23Plus Motion Control are achieved through IMS's
advanced 2nd generation current control. By applying innovative
techniques to control current flow through the motor, resonance
is significantly dampened over the entire speed range and audible
noise is reduced.
The MDrive23Plus 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 operating temperature range of –40° to +85°C pro-
vides long life, trouble free service in demanding environments.
Standard features available in the MDrive23Plus 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
revolution, and full featured easy-to-program instruction set.
Expanded features in the MDrive23Plus 2 version include up to 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 electronically controlled ratio,
or an output clock can be generated fixed to the internal step clock.
For use in environments where exposure to chemical, dust and liquids may occur, a sealed assembly
MDrive23Plus 2 -65 version is designed to meet IP65 specifications.
All MDrive23Plus 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 MDrive23Plus 2 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 a 7 position terminal strip. Plus 2 versions come with pluggable locking wire crimp con-
nectors. Plus 2 -65 sealed versions come with M12/M23 circular connectors.
The MDrive23Plus is a compact, powerful and inexpensive solution that will reduce system cost, design and
assembly time for a large range of brushless motor applications
