| Setting | Axis selected | |---------|----------------| | 0 | 1st axis (X) | | 1 | 2nd axis (Y) | | 2 | Not used (invalid) | | 3 | Not used | | 4 | 3rd axis (Z) | | 5 | 4th axis (A/B) |

Parameter 8901, when set optimally, allows:

This setting "shields" or suppresses the alarm, allowing the machine to continue operating even if the fan signal is missing or faulty. Using the Parameter "Better" While setting 8901#0 to 1

Note: This parameter works in conjunction with memory backup batteries. If parameter 8901 is set, it flags the SRAM area for work offsets as "protected/retained," ensuring that volatile memory keeps the G54 data alive during a controlled power-down, preventing the dreaded "0030 Power-off without memory backup" alarms or data clearing.

The short answer is . Setting Parameter 8901 to a specific non-zero value is statistically better for modern high-speed machining, but only if you understand the trade-offs. This article will explain what 8901 does, why the default setting is outdated, and how optimizing it makes your machine better .

If a replacement fan is unavailable and production must continue, you can set the parameter to 1, but you forced air cooling

Based on your request, it seems you are asking for information regarding a to achieve "better" performance.
