Multi-Axis System with Virtual Axis

[Silverfang-]

Hello Everyone,

I'm new here and relatively new to Machine Expert and Motion Control. I have an application where I need to perform movements of an object using 2 servo drives. So I assume its a virtual axis configuration I need to do but there seems to be very little literature on how to do it.

Can anyone point me to an example of this on Machine Expert or a guide which explains how to do this? I am using a Pacdrive LMC Pro 2 motion controller

Hi Silverfang,
when you create a new project for PacDrive with Machine Expert, you can choose from different examples. The most common one is the "Template Full", which is already set up for use with 2 Lexium drives and a Power Supply.
If you're new to Machine Expert and don't have prior motion experience, I would recommend attending one of our courses. There are several aspects to consider when implementing a motion system. You can find our training at this address:

or you can search for "training" in your regional Schneider Electric website (www.se.com).
Alternatively, there are videos on YouTube posted by some colleagues.

Hello Francesco,

Thanks for your response. Yes although I don't have a wide amount of experience with Machine Expert I have created many applications which successfully run the configuration you are referring to where the axis is a single real axis and a single servo takes care of the movement.

What I need help with is to use a virtual axis (similar to a crank motion where the linear movement creates a rotational path of motion). My actual application demands the system to follow a virtual path of motion by using a twin axis system created by 2 servo motors.

I would love to explore any examples for this (such as robotic arms etc) but I am unable to find resources for this.
