SAFETY SPEED OVER

¿Qué significa SP0757 ?

The CNC CPU detected that the spindle motor speed on the n-th spindle was greater than the safety speed (parameter No. 4372, 4438, 4440, or 4442) during safety monitoring (when the safety check request signal (*VLDPs) is 0). This indicates an unsafe spindle operating speed, which is a critical safety violation.

• Actual motor speed exceeded the configured safety speed limit (P3-01).
• Unexpected acceleration causing speed overshoot.
• Loss of feedback from a speed monitoring device.
• Incorrect deceleration ramp settings.

1. 1

   Verify the values set for safety speed parameters No. 4372, 4438, 4440, or 4442.

2. 2

   Ensure that spindle operation is programmed and executed within the defined safety speed limits.
