Hi everyone,
I'm seeking advice on how to release the holding brake on a motor connected to the CtrlX drive, which is being controlled by a CtrlX Core. Although I'm utilizing the PLC Open library for motion control, I noticed there's no function block in the library specifically for releasing the holding brake. compass mobile login
Is there an alternative library that includes this functionality, or will I need to create a function block myself? It's worth mentioning that I do not have SBC on these drives, so I'm looking for a method that doesn't involve SBC.
Solved! Go to Solution.

Hi Andrew,
I would look into the IL_ECATSoeCommand function block that should be in your ethercat master library of CtrlX PLC Engineering. From there you can issue most any drive command, in this particular case, it looks to be associated with parameter/IDN P-0-0542
Be aware that you will likely have to issue a brake "apply" command afterward to close the brake again. Also be aware for Indradrive, i think you have to set a parameter to allow for external brake control. I don't see that checkbox on a CtrlX drive so perhaps they removed that requirement for this generation of drives.
Below a link to a write up where they go into detail on using the SOE command and SOE read/write function blocks to similar things:
