Excessive position command difference

Hva betyr F2037 ?

The difference between the commanded position and the actual position of the axis is too large, indicating that the drive cannot follow the commanded trajectory accurately. This is often related to tuning or mechanical issues.

• Mechanical binding, obstruction, or excessive load preventing the motor from following commands.
• Insufficient control loop gains (P, I, D) for the application's dynamics, leading to large following error.
• Inertia mismatch between motor and load, or undersized motor/drive.
• Faulty encoder or poor encoder signal quality.

1. 1

   Inspect the mechanical system for any binding, blockage, or excessive friction that would prevent the motor from moving freely.

2. 2

   Review and re-tune the drive's position and velocity control loop gains. Start with conservative gains and increase gradually.

3. 3

   Verify that the motor and drive are appropriately sized for the load inertia and acceleration requirements.

4. 4

   Check encoder cabling for damage and ensure good signal integrity.
