Hello, it is still the same procedure: You have to manipulate the analog output value in OB "MC-PostServo" and to split the analog output value into absolute value and algebraic sign. The handling of the analog output value you could find in system manual, chapter A.10.7. The algebraic sign you send to an digital output of the CPU, connected to the drive. Maybe the better way to do the programming is to write the TO data to a data block (DB) - that means connect the TO to the data block and not to the analog output - and transfer in OB "MC_PostServo" from data block to analog output and DQ by splitting it in absolute value and algebraic sign. |

Hi thank you for you reply! The first picture is the code in MC-PostServo, When I don't add the MC-ServoPost,the waveform is normal,you can see the second picture! When I add the MC-ServoPost,the waveform not normal,you can see the last picture. Attachmentquestion.pdf (201 Downloads) |
