No Origin Proximity Input Signal

Was bedeutet 0200 ?

This fault occurs during an origin search when the 'Origin Detected after Prox Input' parameter is set to 0 (Turns ON and then OFF), but no origin proximity input signal was received. This indicates the machine failed to detect the initial proximity sensor before the final origin, preventing the origin search from completing.

• Faulty wiring of the origin proximity input signal, leading to an open circuit or poor connection.
• Incorrect 'Origin Proximity Input Signal Type' (NC or NO) configured in PLC Setup.
• Origin proximity sensor failure, damage, or mispositioning, preventing proper detection.

1. 1

   Visually inspect the wiring connections for the origin proximity input signal for integrity; measure continuity of the cable from sensor to input terminal.

2. 2

   Access the PLC Setup 'I/O Module Tab Page' using CX-Programmer and verify the 'Origin Proximity Input Signal Type' setting is correctly configured (NC or NO) to match the sensor's operation.

3. 3

   Test the origin proximity sensor operation by manually activating it and verifying the corresponding input signal status at the PLC input terminal.

4. 4

   Ensure the physical positioning of the origin proximity sensor allows for proper detection during an origin search.

5. 5

   Initiate an origin search again from the HMI or programming software.
