Signal allocation
can be modified
Positioning completed (speed coincidence), during servomotor rotation, servo
ready, during current limiting, during speed limiting, brake released, warning,
selecting three of the NEAR signals
Dynamic Brake
Activated at main power OFF, servo alarm, servo OFF, or overtravel
Regeneration
