Estun ProNet drives need to be configured to run with the Acorn Hardware you can do this one of two ways
1 Enter parameter settings using the push buttons on the drive itself This method is actually quite simple and is the
recommended way as it does not require a computer special cable or drive software Refer to page 137 and 140 in the
Estun manual
2 User the Estun Software and Special USB to RJ45 cable
Optional ESView v210 Software unzip and run the exe to install ESView

Method 1 Setup Estun ProNet Drive using the buttons on the drive itself
1 Turn on logic power to the Estun Drive no main power no motor connected
2 On the Estun Servo Drive use the Mode M button to switch to Parameter modeβ
βPn_ _ _β will be displayed
Use Up ο΅ and Down οΆ buttons to change parameter numbers Refer to page 140 in the Estun manual
Once the correct parameter is selected press the Enter ο³ button to view the parameter value
Then edit parameter value by pressing and holding the Enter ο³ until a flashing period cursor
appears
Then Press enter to cycle the cursor to each digit of the parameter
Then use the up and down arrows to change the digits to the desired parameter value
Press Mode M button when you are done editing the parameter to save it
3 Before connecting motor set the initial Estun Servo Drive Parameters that configure the basic setup of
the drive and servo motor being used Some parameters take effect immediately and other require a
power cycle of the drive power off wait 10 seconds and then power back up
a Set the servo drive and motor model with parameters P005 3 P840 1 and P840 2
Read the servo motor model from the ID sticker on the Servo motor itself
Then use the Chart from the Estun ProNet User manual to set P005 3 P840 1 and P840 2
Power Cycle drive at the end of this procedure
If you get a A 43 or A 44 on the Estun servo drive recheck this procedure

4 Input these parameters on the Servo Drive using the display and buttons
Parameter #
Pn000 0110 disables P OT N OT
Pn004 1000 Inverts SIGN
Pn005 _010 sets position mode Pn005 3 sets Servomotor
model and should not be changed
Pn100 0 sets manual gain adjustment
Pn201 256 1 st
Electronic Gear Numerator
Pn202 1 Electronic Gear Denominator
5 Run the Acorn CNC configuration Wizard
a Under Primary System Config Select drive type and then Estun ProNet
b Under Axis Config Set Steps/Revolution to β4096β for the axis that your Estun is connected
c then use the other menus to setup the rest of the machine setup Follow the Acorn Installation
Manuals for guidance
d Click βWrite Settings to CNC Control Configurationβ and click βOKβ follow instructions on the screen
6 Power down the entire control system connect The Motor power to the Drive connect the motor to the drive
7 Power up and test movement of each axis

8 Estun ProNet software is missing a classic βAuto Tuneβ feature so the motors must be tuned by βhandβ
If the motors are smooth and quiet they are probably good to go but if they are βsingingβ and vibrating its time
to adjust the gain settings to achieve the desired smooth quiet operation
In general the more heavy and the more resistance natural damping a machine has the higher the gain
numbers can be And the opposite is true for light and no resistance light to no damping that an axis has
For example a Typical entry level CNC Router like and AvidCNC router with light axes and rack and pinion
runs well with these settings

Using the Estun Esview software to set the drive parameters
1 Power down the entire control system connect The Motor power to the Drive connect the motor to the drive
Plug the drive into the computer via the CN4 connection on the drive and plug the other end of the cable into the PC
Start ESView Software
When installing the ESView v210 software you may get an error message about windows compatibility just skip by that
You can try the newer versions of ESView as well but Iβve had better luck with v210 version
If you have trouble with drivers/cable/connections just set the drive up using the buttons on the drive
Select Online click Search
The software will search for the drive select the drive when it is found
If there are problems try changing the Applied Com

5 Click Test Run β Jog
Make sure the axis can move without running into something Click OK
Click edit and change the jog speed to something fairly slow 250 or so
Click Servo On observe that the indicator goes green
Click Forward and Reverse and check that the motor moves
