Accel/Decel Error

Allen-Bradley · MicroLogix 1400 Programmable Controllers

Was bedeutet 4 ?

The accelerate/decelerate parameters (ADP) are either less than zero, greater than half the total output pulses to be generated (TOP), or exceed a specific documented limit (see page 103). This error faults the controller and indicates an invalid motion parameter. It can be cleared by logic within the User Fault Routine.

Häufige Ursachen

  • Acceleration/deceleration parameters (ADP) set to a negative value.
  • ADP value exceeds half of the total output pulses (TOP) for the PTOX move.
  • ADP value exceeds the absolute limit for the PTOX subsystem as specified on page 103 of the manual.

Reparaturschritte & Checkliste

Klicken Sie auf Schritte, um Ihren Fortschritt zu verfolgen.

  1. 1

    Verify the accelerate/decelerate parameters (ADP) are non-negative and do not exceed half the total output pulses (TOP).

  2. 2

    Check the ADP value against any specific limits documented on page 103 of the manual.

  3. 3

    Correct the program logic that sets the ADP values to ensure they are within acceptable bounds.

  4. 4

    Clear the fault using the User Fault Routine or by cycling power after correcting the ADP values.
