Auxiliary Shaft Servo Input Axis Conflicts with Output Axis
Mitsubishi Electric · MELSEC iQ-R Motion Controller
What does 1BF0H mean?
This minor error occurs when the servo input axis number (1 to 64) specified in [Pr.418] for the auxiliary shaft is set to the same value as an output axis. This conflict prevents the initiation of synchronous control, as the system cannot properly assign input and output roles for the conflicting axis ID.
Common Causes
- The servo input axis number (1 to 64) set in "[Pr.418] Auxiliary shaft axis No." duplicates an existing output axis number in the system configuration.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Verify the value of "[Pr.418] Auxiliary shaft axis No." for the auxiliary shaft, ensuring it is within the valid range (1-64 for servo input axis).
- 2
Check the servo network settings to identify all numbers currently assigned to output axes.
- 3
Modify the setting of "[Pr.418] Auxiliary shaft axis No." to a unique axis number that does not correspond to any configured output axis.
