The servo actuator can't be turned on
No way! What for? Normal power failure can turn!This has not been touched, we are used in the packing machine! A: so do you see the drive?
You say this kind of situation can only explain the motor and magnetic field exists, if it is the driver to stop, but no one stop drives that can signal, then the situation should be reasonable, if the drive power disconnected, and long time or the situation that is not normal.
You mean with your hand? If it's charged, that's normal, and it depends on whether the motor has a brake
