The MDrive Speed Control offers the system designer low cost, intelligent
velocity control integrated with a NEMA 17 or NEMA 23 enhanced torque
stepping motor and a +12 to +48 (MD17 and MD23-4) or +24 to +75
(MD23-7) volt microstepping drive.
The MDrive Speed Control features a digital oscillator for accurate velocity
control with an output frequency of up to 100 kilohertz. Output frequency
will vary with the voltage level on the speed control input. The speed control
input can be adjusted by using one of the following methods:
There are two basic modes of operation: bidirectional and unidirectional. In
bidirectional mode, both speed and direction are controlled by the analog
speed control input. In unidirectional mode, only velocity is controlled by the
speed control input; direction is controlled by a separate digital input.
The MDrive Speed Control has 12 setup parameters which are configured by
using the included IMS Speed Control Interface. These enable the user to
configure all of the operational parameters of the MDrive which are stored in
non-volatile memory.
The versatile, compact MDrive Speed Control is available in multiple
configurations to fit various system needs. These options include: a single
shaft stand-alone device, a rotary motor with optical encoder, a planetary
gearbox, control knob, or an Acme screw linear actuator. The rotary MDrive
Speed Control is also available in three different stack lengths: 13, 15 and 19
for the MD17 and 18, 22 & 31 for the MD23. Interface connections are
accomplished using either a 7 position terminal block or optional 12" (30.5cm)
flying leads.

The IMS Speed Control Interface Software is accessed through the IMS SPI
Interface which is easy to install and use graphical user interface (GUI) for
configuring the MDrive from the parallel/SPI port on your computer. It is
required for configuring your MDrive Speed Control and is included on a CD
with the product, or it may be downloaded at www.imshome.com.
The IMS Speed Control Interface Software features include:
10
10k Potentiometer.
0 to +5V applied directly to the input.
15 - 25kHz (0 to 100% duty cycle) PWM applied to the input.
4 - 20mA or 0 - 20mA applied to input.
Easy installation.
Automatic communication configuration.
Will not set out-of-range values.
Tool-tips display valid range setting for each option.
Ease of use via single screen interface.
