Was bedeutet F111 ?

A malfunction in the safety input enable hardware has been detected, specifically that one of the required safety inputs (S1 or S2) is not enabled. This indicates a problem within the drive's integrated safety circuit or incorrect external safety wiring, preventing safe operation.

Häufige Ursachen

  • One or both of the required safety input signals (e.g., S1, S2) are not active (e.g., open circuit) when safe torque off (STO) is not intended.
  • External safety circuit (e.g., safety relay, light curtain, emergency stop button) has tripped or is improperly wired to the drive's safety inputs.
  • Incorrect configuration of drive safety parameters (e.g., P33-00 to P33-05) related to STO functionality.
  • Break in the wiring of the safety input channels (S1 or S2) to the drive, or a loose terminal connection.
  • Internal failure of the drive's integrated safety circuit (e.g., dual-channel monitoring logic).

Reparaturschritte & Checkliste

Klicken Sie auf Schritte, um Ihren Fortschritt zu verfolgen.

  1. 1

    1. Measure the voltage across safety input terminals S1 and SCOM, and S2 and SCOM (e.g., 24VDC for active, 0VDC for inactive) to confirm their state.

  2. 2

    2. Inspect the external safety circuit for any tripped devices (e.g., E-stop button engaged, safety gate open, safety relay de-energized).

  3. 3

    3. Verify continuity of the wiring from the external safety devices to the drive's safety input terminals (S1, S2, SCOM) using a multimeter.

  4. 4

    4. Confirm that drive safety parameters (e.g., P33-00 "STO Enable") are configured correctly for the application (e.g., set to "Enabled" if using STO).

  5. 5

    5. If the drive has diagnostic LEDs for safety inputs, observe their status to pinpoint which channel (S1 or S2) is not enabled.
