During the process, when transporters are geared with MC_GearIn instruction, transporter 2 starts to rotate backwards, randomly. I don't notice any mechanical problems can affect the transporter movement. Has someone had similar problem? Could I get any ideas how to solve the problem?

	Regards, Jacek What is confusing you is the fact that you never see a number but always its digit representation. So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine

What kind of mechanics do you have? Is it a linear axis or a rotary axis? Maybe the synchronization is done backwards because the slave drive positionwise is already standing further than the master?
	Best regards, Robert

After changing the gain in control loop settings and dynamics limits of drives, I was able to obtain satisfactory results. Now I have one more problem. I have to keep the product at the set distance. We make passive homing with reflection sensor during the conveyor move. Unfortunately, we are not able to stop the object at a given distance, we get an error of +- 3-20 cm at a given distance of 6 m. We use 6ES7 512-1DK01-0AB0 and G120 with CU240E-2 PN. Are we able to get a maximum error of 5 cm on the equipment used? Does the technology block cycle depend on the controller cycle? Encoders shows the correct move value, but manual measurement gives us a 3-20 cm error. Attachment Bez tytułu.png (57 Downloads)
