Error power supply home switch

What does F270 mean?

The DIAX04 SSE-03VRS drive's power supply for the home switch input has an error. This implies that the voltage supply to the homing sensor is out of specification, missing, or there is an overload/short circuit on the output. This renders the homing function unreliable or inoperable, preventing accurate machine referencing.

• Short circuit or overload on the power supply output for the home switch.
• Damage to the wiring between the DIAX04 SSE-03VRS and the home switch.
• Faulty home 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.

Click steps to track your progress.

1. 1

   Disconnect the home switch wiring from the DIAX04 SSE-03VRS drive input. If the fault clears, the issue is external.

2. 2

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

3. 3

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

4. 4

   Test the home switch for proper operation and current draw. Replace if faulty.

5. 5

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