I agree with you Terence however we want to discard that bad encoder siganals are the only cause for the behaviors we're seeing. Thanks ------------------------------ Nelson Munoz ------------------------------

EDIT: linkified for convenience -FL Hi Jonathan, I'm not sure if this can answer your question but I'm seeing that Rockwell sells the complete Replecement kit for HPK series motors and provides the installation instructions. https://literature.rockwellautomation.com/idc/groups/literat ...

Hi Jose and thanks for your answer. The first document was exactly the one that I was using to take the idea for the control but unfortunately it only describes the way that operates the control but nothing realted to configuration. For the TN 516124 it's telling me that I don't have ...

Hi Vincent, Basically the problem here is that we have a 3rd party motor from Andritz Permanente Magnet 467 V 126 Amps, the encoder is a sensitec incremental sensor module and we're using a motrona FM210 Frequency multiplier to adapt the signals to the required 2048 pulses. For this reason ...

PM Offset test in load sharing configuration between Permanent Magnet motors

Hi everyone. We have a load sharing configuration betweeen 2 permanent magnet motros coupled to the same shaft and with only one encoder signal for both. My question is how can prevent or configure sequentially the drives to perform the Auto PM Offset test after a power cycle?. So it's clear that ...

Thanks Terence, We know for sure we're having issues with the encoder feedback signal, we already verified that in the osc, but we need to know if we would be expecting the current behaviors that we're seeing according to this problem. ------------------------------ Nelson Munoz - ...

Hi everyone For a PowerFlex 755 with PM motor with incremental encoder. If we have noise and/or encoder inaccuracies that affect encoder feedback over time will this jeopardize motor commutation over time? On the first start after a power cycle, we do the PM Offset test and the relationship ...

Hi everyone, actually I have the following drive configuration: There are 2 Permanent Magnet motors driving the anvil roll – one on the drive side and one on the non-drive side. The motors are sized at 76.28 kW each (152.56 kW combined). Each anvil motor is controlled by a 302 Amp PowerFlex755 drive ...

Hi everyone, Right now there is a system with a Virtual Master Axis defined in meters, it is moved using MAJ. This master is guiding a winder defined in meters using a MAG with a fix gear value and the winder is guiding a spindle defined in degrees moved by MAG with Master reference Command and ...

Hi Vincent, as you can see in the image below the routine for the motion instructions (04_UnwinderAxis) is running in a periodic task with 10 ms period the same for the tension control routine _04_TensionControl. I don't know if this helps a little bit to understand the use of 2 MAJ instead of 1. ...

Thanks Vicent it was a really nice explanation about the use of the MAJ instruction to superimpose over an active MAG but I have a plus. Why do you think they are using 2 exactly the same MAJ instructions for this control happening one in one scan and the other one in the next scan so they are interspersed?. ...
