Dear Mr. Kolev, I'm not sure I understood correctly. But this is my take on your question: When the STO of the slave is triggered, store the current master position (e.g. 225 units) After the reset of the slave error, call MC_SetPosition on the virtual master and reset it to the stored position (225 units) Optionally, before MC_CamIn is restartet, move the slave back to the slave position corresponding to the stored master position. (If you do this, no ramping in will be necessary) Restart MC_CamIn,...

Dear Mr. Kolev, can you please explain a little more: what happens at an STO? I assume the slave axes will be stopped and retain their current position? How, then, do you call MC_CamIn after the STO? Do you restart it with a new rising edge, but on the same master position as before the STO? Which StartMode are you using, is the cam slave absolute or relative, master absolute or relative? Are the slave axes modulo or finite axes? Best regards, Georg Seidel

Hi jgalaska, the parameters and their valid ranges are described here (0). In particular, the parameter d1 must be non-positive (<= 0).

Hi bertus, the coordinate systems used in SoftMotion CNC are all right-handed. The CNC editor uses isometric projection. This can be confusing, as in your example. The y-axis seems to point into the screen, away from the viewer. However, this is just an optical effect. If you turn on the (experimental) perspective projection (must be added to the CNC tool bar using tools->customize), you can see that the coordinate system is in fact right-handed. Best regards, Georg

Hi aniket-b, the maximum cycle time of the EtherCAT_Task is very high, ca. 35 ms. Could you please check if this is just the first cycle after starting the application or if it happens during motion? (You can reset the times in the task configuration by right-clicking in the "monitoring" tab.) Another thing to try: put the SoftMotion_Planning task on a different core. Best regards, Georg

Hi aniket-b, this error has nothing to do with the scara3 kinematics, or robotics, or SoftMotion. It means that the EtherCAT bus is not synchronized. The usual cause is that the realtime of the PLC is not sufficient. See https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_basic_common_errors.html for details and ways to solve the problem. You can also check the PLC log for additional information about the error. Best regards, Georg
