I appreciate the information and I had found these too. But I was looking for something directly related to the interface commands. To explain the specifics of my problem, if I have an EStop on my system, it puts the drives in STO. I have not figured out a way to re-attach them to the kinematic after this. The drives are stuck in AB after this event. No command of the drive, for example to ModeAH has an effect. The kinematic commands also have no effect, moving from Mode_Coord_AB to _AH or _Standby, etc.
My thought is that when an STO event occurs on the axes that are joined to the kinematic, that I need to command the kinematic in a certain way to follow the actual drive state. And then, I'm suspecting, there is a sequence to recover from the STO state once the safety controller releases the drive from STO. But I have not found a way to do this yet. Right now, the only sure way is to Cold Stop the PLC which is similar to a power cycle. Then the kinematic works as expected to coordinated the axes correctly.
