The PC (process complete) bit of MAS command does not clear

[Parya 0]

Hello everyone,

I have this weird problem that the PC (process complete) bit of MAS command does not clear after a cycle time. 

As you may probably see in the picture attached when the desired torque has been reached, the servo has to be stopped using MAS command; however, this is good only for one cycle!! The PC bit will remain on even when the whole sequence gets unlatched/reset. I have to manually reset this bit. I was wondering if you could help me with this issue, please? 

Thank you!

This is documented behavior.  Instructions that use the Process Complete bit will reset it themselves when they are started.  In the motion instruction set manual, look in Preface => Instruction Timing => Process Type Instructions.
