Interesting. In the SMC_LimitDynamics case, do you reduce the maximum velocity of the SMC_GeoInfo based on the third derivative of the spline?

Hi gilad, I cannot tell for sure. But I think it should work on any PLC that is capable of doing motion control. Best regards, Georg

Hi gilad, the missing license does not prevent the axis from being enabled. As far as I know, Festo distributes a CODESYS SoftMotion driver for the CMMT drives together with their software. I would contact Festo and ask for the driver. Best regards, Georg

Dear josepmariarams, this (internal) function has been removed with SoftMotion 4.17.0.0. We do not have public functions to compute the extrema of a polynomial. On which polynomials exactly did you call SMC_Polynomial_AbsMaxLocs? (Maybe if I understand better how you limit the jerk I can come up with an alternative.) There is no functionality to limit the jerk of individual axes in the CNC. With SMC_LimitDynamics, you can limit the velocity and acceleration of cartesian (X/Y/Z) and additional (P/Q/U/V/W/A/B/C)...

Hi alex-n, are there any errors before the crash happens: MC_Phasing.Error, MC_Phasing.CommandAborted, what does the PLC log show before the crash? Does one of the drives show an error? You can achieve the same effect as MC_Phasing by using MC_GearIn and MC_MoveSuperImposed. But probably there is some problem in your application independent of MC_Phasing that can lead to the crash. Best regards, Georg

Hi darwin03, when all joints are 0°, then the 6-axis robot is in a so called singularity. This means that it is in a special position where it cannot move freely in all directions but is restricted by its own construction. For a simple example, imagine a scara robot where the arm is fully stretched. In this position it cannot move freely. You can find a lot of information about robot configurations in the www. As far as CODESYS SoftMotion Robotics is concerned, this page holds the most important...

Hi transcend, most likely cause: one of the motion FBs was not called in each IEC cycle. See https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_basic_common_errors.html. A different possible error, if you are using buffermode buffered or blending: the execution order of the motion FBs was wrong. See https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_buffermode_execution_order.html. Best regards, Georg
