SPEED CONTROL

The MDrive17Plus Speed Control offers 

system designers cost effective, program-

mable velocity control integrated with a 

NEMA 17 high torque 1.8° brushless step 

motor and a +12 to +48 volt microstepping 

driver.

The MDrive17Plus Speed Control features 

a digital oscillator for accurate velocity 

control with an output frequency of up 

to 5 Megahertz. Output frequency will 

vary with the signal applied to the speed 

control input and can be limited by the 

amount specifi ed by the Maximum Veloc-

ity parameter. 

Speed can be adjusted using three modes 

of operation: voltage, current and PWM. 

The ranges are 0 to +5 volts and 0 to 

+10 volts in voltage mode, 0 to 20 mA 

and 4 to 20 mA in current mode, and 15 

to 25 kHz in PWM mode. This allows the 

MDrive17Plus Speed Control to be driven 

by a wide variety of sensors and control 

devices.

There are two basic methods for control-

ling the velocity: bidirectional and unidi-

rectional. By moving the center point, both 

speed and direction are controlled by a 

potentiometer or joystick. 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 MDrive17Plus Speed Control has 18 

setup parameters, which may be con-

fi gured using the supplied IMS Analog 

Speed Control GUI, or a user-developed 

front-end communicating over SPI. The 

setup parameters enable the user to con-

fi gure all MDrive operational parameters 

which are stored in nonvolatile memory.

The MDrive17Plus is a compact, powerful 

and cost effective motion control solution 

that will reduce system cost, design and 

assembly time for a large range 

of brushless

step motor applications. 

The IMS Analog Speed Control is a soft-

ware GUI for quick and easy parameter 

setup of the MDrivePlus Speed Con trol 

from a computer's USB port. GUI ac-

cess is via the IMS SPI Motor In ter face  

available at www.imshome.com. The IMS 

interface is also used to upgrade MDrive-

Plus Speed Control fi rmware. 

IMS Analog Speed Control features:

• Easy installation.

•  Automatic detection of MDrivePlus ver- 

  sion and communication confi guration.

•  Will not set out-of-range values.

•  Tool-tips display valid range setting for  

 each 

option.

•  Simple screen interface.
