Fanuc - Parameter 8901 Better __link__
While changing this parameter can clear an immediate alarm, it should be done with caution:
Servo lag in X axis (non-moving during tapping) was being unnecessarily referenced. The sync loop included X, causing phase shift at high spindle speeds. fanuc parameter 8901 better
When 8901=2, the CNC analyzes the interior angle of a corner. If the angle is acute (< 90 degrees), the control automatically reduces the feedrate in anticipation. When 8901=1, the machine often slams into the corner, deflects the cutter, then speeds up. While changing this parameter can clear an immediate
In Fanuc CNC systems, is specifically used to manage fan-related alarms , such as the "701 Fan" alarm, which occurs when a system cooling fan fails or stops rotating properly. If the angle is acute (< 90 degrees),
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
Fanuc parameter is primarily used to mask the ALM701 fan overheat alarm on CNC systems like the Series 0i-B, 0i-C, and 18i-TB. Core Function and Use Alarm Suppression : Setting bit 0 of parameter 8901 to
