ILLEGAL SPINDLE PARAMETER SETTING

What does SP1996 mean?

This Fanuc Series 0i-D/0i Mate-D spindle alarm indicates an incorrect spindle assignment or that the number of configured spindles exceeds the system's maximum allowance. Parameters 3701#1, #4, 3716, and 3717 are typically involved.

• Incorrect assignment of spindle axes in parameters (e.g., Parameter No.3701#1, #4).
• The total number of spindles configured (Parameter No.3716) exceeds the system's maximum capacity.
• Parameter No.3717 (spindle control type) is incorrectly set for the installed spindle amplifier.
• Conflicting or inconsistent spindle-related parameter settings.

Click steps to track your progress.

1. 1

   Verify Parameter No.3701#1 (spindle axis assignment for axis 1) and No.3701#4 (if applicable for axis 2) are correctly set according to the machine configuration.

2. 2

   Check Parameter No.3716 (number of spindles for the system) to ensure it does not exceed the maximum allowed for the specific CNC model.

3. 3

   Confirm Parameter No.3717 (spindle control type) is accurately set corresponding to the installed spindle amplifier and motor type.

4. 4

   Review all spindle-related parameters against a known good parameter list or the machine's specifications.

5. 5

   If any parameters are found to be incorrect, adjust them and then cycle power to the CNC system to apply the changes.
