Access EPOS2 70 /10 via LabVIEW

I am developing a LabVIEW vi to control two EPOS2 70/10 and brushed DC  motors and  I use absolute SSI encoder.

 

1). I would like to know If there are any inbuilt  VI's to control the software position limit in the EPOS controller. If not, how to access the position limit to avoid damaging my test object. 

 

2). I would like to clarify how the mode of connection should be established in Labview for interface and baud rate settings for the Master controller and Slave controller. Do I need to have different interface name for both the controller? since the baudrate of Master controller RS232 has 115k bits and slave controller CAN has 50k bits.. But as of now it works fine when I use same interface and baud rate as of master controller to both controllers. I want to verify what is the standard way of initializing the slave controllers.
 
3). I am using the position Window VI in my labview setup for position regulation. I also included the avgvelocity and avgcurrent vi while using the position window. When I introduce the Avg. velocity and current VI, I dont get the precise values as expected. I am worried that after introducing position Window my average values are getting disturbed. How to solve this issue to get precise avg. Velocity and current?

Hi pushpakp,

 

what LabVIEW Version are you using?

 

Are you using the Softmotion Module:

https://www.ni.com/en/support/downloads/software-products/download.labview-softmotion-module.html

 

Or the EPOS2 Drivers:

Best wishes

Hi,

 

these are Third-Party Drivers and for them you will get support via http://support.maxonmotor.com.

 

You should contact Maxonmotor for this.

to answer your "2nd question" , you have two options :

 

1) Connect both EPOS2's serial interface to your pc = 2 cables

 

2) Use the CAN Gateway over the EPOS2

 

check this thread Parrallelism-EPOS

 

 

How it's properly cinfigured for industrial use: I think with a CAN Master interface. 

 

Note: The Vi's from Maxon work fine, I use them on LV2014.
