How to monitor OP mode in Panasonic A6B Ethercat

Now, do I need to invert "lcec.0.0.drivestatus-0" ? How it can be done?
Maybe try the 'NOT' component:
linuxcnc.org/docs/devel/html/man/man9/not.9.html
 


I think I already tried using "not" component, can you confirm this is right format?

try running this in terminal:

watch -n 0.1 ethercat slaves

however drives not getting to OP mode must have a reason. What hardware are you on? I have similar issue with RPI5 and generic driver. I tried faster servo threads, but developers told me, that generic driver is only good for 1 000 000 ns servo thread.

I know nothing about EtherCAT, so I have no idea if you can get an inverted value back from the drive. What I suggested was using the built in HAL component called 'NOT'. For which you would need to use 'loadrt' and 'addf' commands and connect the input and output pins in hal.

You really should give Ethercat a try! Some Ethercat settings can have the direction altered by changing a SDO setting. But I doubt a status pin will.

You can run it multiple times to find the servo drive that can OP every time. Use ethercat sii_read to read the sii data in it and compare it with the sii data in the drive that cannot OP to find the difference. The easiest way is to use ethercat sii_write to write the good sii data. It has been several months since I solved this problem and this problem has never appeared again.
