No Origin Input Signal

¿Qué significa 0201 ?

This fault occurs during an origin search when the main origin input signal was not received. This prevents the system from precisely determining its home position, indicating a failure to detect the final origin marker.

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

1. 1

   Visually inspect the wiring connections for the origin 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 Input Signal Type' setting is correctly configured (NC or NO) to match the sensor's operation.

3. 3

   Test the origin input 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 input sensor allows for proper detection during an origin search.

5. 5

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