Press Unexpectedly Stopped After Starting

Beckhoff · TwinSAFE Logic FB

¿Qué significa 0x4020 ?

The PressStarted input was TRUE, indicating a commanded motion, but the position subsequently stopped ('Stopped' changed to TRUE) after having moved. This suggests an unexpected halt during a commanded press operation, which could be due to an obstruction, overload, or sensor fault, potentially damaging equipment or causing an unsafe state.

Causas comunes

  • Press stopped unexpectedly after starting.
  • Sudden loss of power to the drive.
  • Overload trip during initial movement.
  • Emergency stop activated unintentionally.
  • Control system error causing premature shutdown.
