Short-Time Overload

What does SP0029 mean?

The spindle motor has experienced a short-duration overload condition, exceeding its temporary torque limits. This can occur during heavy cutting or rapid acceleration/deceleration.

• Spindle motor is commanded to produce torque beyond its momentary rating.
• Rapid acceleration or deceleration commands are too aggressive.
• Machine load suddenly increases beyond expected levels.
• Parameter P2-14 (Short time overload limit) is set too low.

Click steps to track your progress.

1. 1

   Review programmed feed rates and spindle speeds for sudden changes.

2. 2

   Measure motor torque output or current draw (P5-04) during transient load.

3. 3

   Adjust P2-14 parameter to a more suitable value for the application.

4. 4

   Examine machine operation for unexpected mechanical binding.
