Hi all,
Just looking for some advice and feedback from anyone who has used a PowerFlex 525 for simple positioning control.
We have an application where we have a flighted conveyor which we are placing empty containers onto. We need to index this conveyor a set distance or flight every move sequence (lets say exactly 300mm for simplicities sake), to put these containers underneath a filling head.
I've been told a PF525 with encoder is suitable for this task, as it can be put into position mode and told to increment this distance, however I'm concerned with the accuracy or accumulative error that may occur as I can't find any information in the manuals or on the knowledgebase about what type of accuracy can be achieved.
I've been told verbally by one of our distributors that accuracy to within half a motor revolution can be achieved, which if coupled to a high ratio gearbox may not equate to much on the drive end. I am not completely sold on the idea.
This is a retrofit to an existing system and trying to avoid going to a servo drive/motor at this stage.
Interested to hear peoples opinions.
Cheers.
