Incorrect direction of motion

Hva betyr F7031 ?

This safety technology error indicates that the IndraDrive MPx02 has detected motion in an incorrect or unintended direction, violating a safety-related directional monitoring function. This could be due to a control error or external influence, leading to an immediate safety stop.

• Incorrect parameterization of safety-related direction monitoring (e.g., S-0-0102 'Safe direction').
• Programming error in the motion controller causing a command for the wrong direction.
• Motor phase reversal or encoder wiring issue, causing actual motion to be opposite of commanded.
• Mechanical system defect (e.g., backlash, broken gear) leading to unintended direction of movement.
• Encoder fault providing inverted or incorrect direction feedback.

1. 1

   Review and adjust the safety-related direction monitoring parameter (e.g., S-0-0102) in the IndraDrive MPx02 to ensure it aligns with the intended safe directions of motion.

2. 2

   Verify the motion program in the master controller or PLC, ensuring correct direction commands are issued.

3. 3

   Check the motor phasing and encoder wiring for correct connections. If necessary, reverse motor phases (U, V, W) or encoder direction parameter (S-0-0130 'Encoder direction of rotation').

4. 4

   Inspect the mechanical system for excessive backlash, loose couplings, or other defects that could cause unintended reversal.

5. 5

   Verify the motor encoder for correct direction sensing, checking for potential noise or signal issues.
