I am getting error, Master period /Slave period of a cam must be an integer. How do I get rid of this error. I am using MpAxisCoupling function block to configure the Cam. [image]

Hi, Option 1. Change the CAM to contain 3 Periods. 0,1666666667. → 1 0,3333333333 → 0 … 1 → 0 Option 2. Adapt the Masterscaling with a Factor *1/3 As 1/3 is 0.3333333 this is a bad value for this option. 1/2 = 0.5 would be better, but this is not what you desired. You always have to be …

Thanks for the help. I could not put any CamID value . It shows error in the logger as , Value”1” for CamID is invalid. [image]

Hi, The CAM must be transfered to the ACOPOS Axis were it will be used. This can be done via a ChannelFeature or during Runtime via a Functionblock. Functionblock CamPrepare ChannelFeature Cam must be part of the Software Configuration [image] Add Cam List CamList [image] Add Cam …

Hi Michael, Thanks for the help. The slave axis(gAxis_2) synchronize with the master axis(gAxis_1), but I am not getting the correct position wave form and the velocity goes to negative. [image] [image]

Hello, good to hear that you were now be able to get to Synchronised Motion. First about you CAM Curve The Y-Axis is the Slave Position at a spezific X-Axis Master Position. In the first half of you curve you move the slave in a positive direction as long as the master reaches the 0,5 units mark…

Thanks Michael, I am able to trace one cycle of the slave position in one cycle of the master position as seen below. [image] How can I get 3 cycles of slave position in one master position cycle.

Hi,

try making the cam 0/0 → 1/1

An then Scale it via the FB:
Coupling FB

Scaling could be for example:
Master 36000(360°)
Slave 72000(720°)

depening on your scaling of the axes

That way the slaveaxis makes 2 revolutions while the master makes one.
