Error power supply travel limit switch

Was bedeutet F271 ?

The DIAX04 SSE-03VRS drive's power supply for the travel limit switches has an error. This means the voltage supply to the limit sensors is out of specification, missing, or there is an overload/short circuit on the output. This compromises critical safety functions, as the drive cannot reliably detect axis travel limits, risking mechanical damage or injury.

• Short circuit or overload on the power supply output for the travel limit switches.
• Damage to the wiring between the DIAX04 SSE-03VRS and one or both limit switches.
• Faulty limit switch drawing excessive current or internally shorted.
• Internal fault within the DIAX04 SSE-03VRS drive's power supply circuit for sensor inputs.
• Loss of 24VDC control voltage feeding the DIAX04 SSE-03VRS input section.

1. 1

   Disconnect all travel limit switch wiring from the DIAX04 SSE-03VRS drive inputs. If the fault clears, the issue is external.

2. 2

   Measure the voltage at the limit switch power supply output terminals on the DIAX04 SSE-03VRS. Verify it's within specification (e.g., 24VDC).

3. 3

   Check the wiring to each limit switch for shorts to ground or power, and for continuity.

4. 4

   Test each limit switch for proper operation and current draw. Replace any faulty switches.

5. 5

   If the fault persists even with switches disconnected, there may be an internal fault with the DIAX04 SSE-03VRS drive's input power supply circuit.
