Clamp responded too often

What does 0x2387 mean?

This fault occurs when the maximum current of the axis (display in 0x2DDF:002) has been reached too frequently in succession. This indicates the system is hitting current limits repeatedly.

• Repeated mechanical jamming or obstruction in the driven axis, causing high current spikes.
• Insufficient motor sizing for the application's peak torque demands, leading to frequent current limit hits.
• Acceleration/deceleration ramps (e.g., P2-10, P2-11) configured too aggressively for the motor's capabilities and load inertia.
• Motor brake (if present) engaging or disengaging incorrectly, causing transient overcurrents during motion.
• Damaged or worn mechanical components (e.g., bearings, gears) increasing friction and required motor torque.

Click steps to track your progress.

1. 1

   Monitor the actual current (0x6078) and torque reference via diagnostic tools during operation to identify peak load events.

2. 2

   Inspect the mechanical system for binding, misalignment, or obstructions preventing free movement of the axis.

3. 3

   Increase the acceleration and deceleration ramp times (e.g., P2-10, P2-11) in small increments and retest.

4. 4

   Verify the motor sizing against the application's peak and continuous torque requirements. Consider upgrading the motor or drive if consistently undersized.

5. 5

   Check the motor brake operation and wiring (e.g., terminals X1:1, X1:2) for proper release and engagement timing.

6. 6

   Lubricate moving parts and inspect bearings for excessive wear, replacing as necessary.
