AKD IL.LIMITP / IL.LIMITN Behavior | 08 Mar 2018 | |



I was playing around with an AKD and I tried to change the current limit to avoid breaking things in case some mechanical part is blocking the motion. I read the manual and I found the two limit variables: IL.LIMITP and IL.LIMITN and they work well. The thing is: when I set the current to a small value and force it with my hand to simulate something blocking the motion, the drive simply disables without returning any warning or fault. Is this right? I would expect to get some fault from that.

Thank you!

I can not reproduce this with a simple AKD and Workbench setup. I think he is using a Fieldbus. I asked him to try again without the fieldbus.

Thank you for the reply, Dan. I was testing it using a PDMM and KAS. With a simple AKD and WorkBench it worked properly.

This may have been caused by a program running that was monitoring position fault. If you are using one of the templates, you may find a program called FaultMonitor. If so, you may want to increase the variable Axis1PosErrorLimit or Axis2PosErrorLimit. This is for a version of the PLCOpen FFLD template.

Ron, I found out that was the case. The PDMM was disabling the drive. Thanks for the reply!
