Insufficient Press Movement

Beckhoff · TwinSAFE Logic FB

¿Qué significa 0x4021 ?

With the PressStarted input TRUE and the system not explicitly stopped ('Stopped' is FALSE), the position did not change by at least the MinPositionChange within the MoveDetectionTime. This means the press initiated movement but did not travel the expected minimum distance within the allotted time, possibly due to a partial jam or restricted motion, impacting process quality or safety.

Causas comunes

  • Insufficient movement detected in the press mechanism.
  • Actuator did not travel the required distance.
  • Encoder or position sensor malfunction.
  • Low torque from the motor.
  • Mechanical binding preventing full travel.

Pasos de reparación & Lista de verificación

  1. 1

    Physically inspect the press mechanism for any partial obstructions, increased friction, or binding that limits movement.

  2. 2

    Verify the motor and drive system are delivering adequate torque and speed.

  3. 3

    Check the position sensor accuracy and resolution, ensuring it reliably detects small position changes.

  4. 4

    Adjust the MinPositionChange and MoveDetectionTime parameters if the physical system characteristics have changed or were initially misconfigured.
