Safety rel. position limit val., exc. in neg. dir.

What does F7012 mean?

This safety technology error indicates that the motor's actual position has exceeded the safety-related negative position limit value configured in the IndraDrive MPx02. This is a critical safety violation, implying the machine has moved beyond its safe lower boundary, requiring an immediate safety stop.

• Incorrectly set safety-related negative position limit (e.g., S-0-0194) in the IndraDrive MPx02.
• Encoder counting error or offset, leading to incorrect actual position reporting.
• Loss of control or unexpected motion command pushing the axis beyond the limit.
• Mechanical overrun due to inertia or external forces.
• Faulty safety limit switch or sensor that failed to activate or register.

Click steps to track your progress.

1. 1

   Review and adjust the safety-related negative position limit parameter (e.g., S-0-0194 'Safety related position limit negative') in the IndraDrive MPx02, ensuring it is correct for the machine's physical limits.

2. 2

   Verify the motor encoder for accurate position feedback. Check for mechanical slippage, loose couplings, or encoder damage.

3. 3

   Inspect any external negative travel limit switches or sensors and their wiring for proper function and connection.

4. 4

   Check the commanded motion profile and ensure that no trajectory attempts to exceed this limit.

5. 5

   Perform a re-referencing or recalibration of the axis position, if applicable.
