of this parameter allows maintenance personnel to temporarily "shield" or bypass the alarm to keep the machine running while waiting for a replacement fan. Function and Settings The parameter is typically labeled (or PRM) and operates on a bit-level basis: Bit 0 (Value = 0):
Here is a technical overview text regarding optimizing Fanuc parameter settings for improved performance:
In high-stakes manufacturing, a halted CNC machine is an expensive bottleneck.
A machine that shuts down at 2:00 AM on a Friday requires emergency repair bills and premium overnight shipping. Using Parameter 8901 to safely extend operations lets you order a budget-friendly replacement component and schedule the installation during a natural shift change later in the week. Step-by-Step Guide to Safely Changing Parameter 8901
While changing this parameter can clear an immediate alarm, it should be done with caution:
Fan detection is active. If the fan stops, Alarm 701 is triggered.
A new fan cost is negligible compared to a new servo drive. Conclusion
Press the SYSTEM key, then the PARAM soft key. Type 8901 and press [NO. SRH] .
If you are experiencing Alarm 8, 9, or A , it signifies an abnormal current or a short circuit in the amplifier or motor, which requires immediate hardware inspection rather than parameter adjustment.
Understanding the common pitfalls associated with Parameter 8901 is essential to using it effectively.
When the FANUC control detects a fan failure, it triggers an alarm—usually a —and the machine stops to prevent overheating. By setting Parameter 8901#0 to 1, you tell the CNC to stop monitoring the fan, thus clearing the alarm.
: Do not let the internal cabinet ambient temperature exceed 45°C (113°F).
