DESCRIPTION
The MDrive17 Speed Control offers 
the system designer low cost, intelli-
gent velocity control integrated with a 
NEMA 17 high torque stepping motor 
and a +12 to +48 volt microstepping 
driver.
The MDrive17 Speed Control fea-
tures a digital oscillator for accu-
rate velocity control with an output 
frequency of up to 100 kilohertz. 
Output frequency will vary with the 
signal applied to the speed control 
input. Speed can be adjusted by 15-
25kHz PWM, 0-20mA, 4-20mA or 
0 to +5 volts.
There are two basic modes of opera-
tion: bidirectional and unidirectional. 
By moving the center point, both 
speed and direction are controlled 
by the IMS Analog Speed Control GUI. 
By setting the center point to zero or 
the lower end of the potentiometer, 
only velocity is controlled by the speed 
control input; direction is controlled 
by a separate digital input.
The MDrive17 Speed Control has 12 
setup parameters, confi gured  using 
the supplied IMS Analog Speed Con-
trol GUI. The setup parameters en-
able the user to confi gure all MDrive 
operational parameters which are 
stored in nonvolatile memory. 
The versatile, compact MDrive17 
Speed Control is available in multiple 
confi gurations to fi t various system 
needs. These options include a single 
shaft rotary motor, a dual shaft rotary 
motor available with optical encoder 
or control knob, a planetary gear-
box, or a long life Acme screw linear 
actuator. The rotary MDrive17 is 
available in single, double and triple 
stack sizes: 13, 15 & 19. Interface 
connections are accomplished us-
ing either a 7 position pluggable 
terminal strip or 12.0” (30.5cm) 
fl ying leads. 
CONFIGURING
The IMS Analog Speed Control is 
a required software GUI for quick 
and easy parameter setup of the 
MDrive17 Speed Con 
trol from a 
computer par 
al lel/SPI port. GUI 
access is via the IMS SPI In 
ter -
face in 
clud ed on the CD shipped 
with the product, or down 
load at 
www.imshome.com. An optional 
Parameter Setup Cable is available 
for ease of connecting and confi gur-
ing the MDrive.
IMS Analog Speed Control features:
•  Easy installation.
• Automatic detection of MDrive 
version and communication 
confi guration.
• Will not set out-of-range values.
• Tool-tips display valid range 
setting for each option.
• Single screen interface (below).
Confi guring the MDrive Speed Control 
is simplifi ed with the IMS Analog Speed 
Control's single screen interface.
