I. Introduction
What is RAGU V1.0?
It is a user friendly evaluation tool that enables to demonstrate
and evaluate the function of stepping motor driver IC’s.
What Can We Do with this Tool?
This tool enables the user to evaluate or demonstrate certain
functions of motor driver IC’s without the use of bulky
instruments (e.g. oscilloscope, power supply).
With its Software and Hardware, the user can rotate stepping
motors, adjust current limit, control current decay, change
excitation mode, and monitor waveform of output voltages and
currents.

Accessed via: View -> Dynamic Window Menu Item
The Dynamic Settings window allows the
user to preprogram a sequence of
configurations to the device.
The Run Cycle determines the repeat count
for the whole sequence.
The repeat delay defines the time between
each cycle.
Press Start to begin the dynamic sequence.
Temperature Monitor

Accessed via: View -> Tj Monitor Menu Item
The Temperature Monitor window allows the
user to preprogram a sequence of
configurations to the device in order to
monitor the temperature at each setting.
At the end of the sequence, the logged
temperature data is plotted into a Microsoft
Excel Spreadsheet.
Press “Start” to begin temperature
monitoring.
Press “Save Chart” to plot the existing
temperature log in a spreadsheet.
Calibrate
Figure 20. Calibration Settings
The calibrate function is found under the Help Menu.
Note: Ensure that all oscilloscope functions are
turned off before calibrating the device. Calibrating
the device while using the oscilloscope may result to
an incorrect calibration.
