1. INTRODUCTION AND THE FUNCTIONS
Introduction
The ProTuner is a software tool designed to configure and tune our DMD & DM series
digital stepper drives including DM805-AI. The user can tune the current loop and adjust
the anti-resonance parameters via this software.
Work Platform
After installing the software and open it, the software is displayed as follows.

2. HOW TO USE THE SOFTWARE
Open a file
If you want to load the configuration data from a file in the PC, click on the File->Open. The
parameters in the software’s workspace will be updated.
Save as a file
Click Drive->Save As to save the data in current workspace to a file and rename it.
Connecting Drive
Connect to Drive window appears every time when you open ProTuner. Select the serial
port, leave the baud rate as default 38400 and click on the Open button. The software will
connect to the drive and read the settings. It may take several minutes.
Before connecting the drive, please make sure:
1) The RS232 cable .has been connected between the drive and PC
serial port;
2) Power has been applied to the drive and the green LED is on.

Caution
The motor is no need to connect to the drive if you just want to change
the parameters but not tuning.
Do not connect or disconnect serial cable when drive is powered on. The
drive’s communication circuit may be damaged.
Current Loop Tuning Window
It is used to configure current loop parameters according to different motor. In the tuning
window, user can set proportional gain, integral gain and test value.
NOTES: After finishing the input of the number, don’t forget to hit the “Enter” key in the
keyboard to confirm new value.

Proportional
Gain
Increase Proportional Gain (Kp) to make current rise
fast. Proportional Gain determines the response of the
drive to current setting command. Low Proportional
Gain provides a stable system (doesn’t oscillate), has
low stiffness, and large current error, causing poor
performances in tracking current setting command in
each step. Too large Proportional Gain values will cause
oscillations and make the system unstable.
1 –65535
Integral Gain
Adjust this parameter to reduce the steady error.
Integral Gain helps the drive to overcome static current
errors. A low or zero value for the Integral Gain may
have current errors at rest. Increasing the Integral Gain
can reduce the error. If the Integral Gain is too large,
the systems may “hunt” (oscillate) about the desired
position.
1 –65535
Test Value
The current amplitude for the step response. T his
value sh o uld not exceed the maximum output
current of the drive.
0.5 –5A
Test Button
Click this button to activate the test. A target curve (red)
and an actual curve (green) will be displayed on the
screen for user’s analysis.
