FANUC Alarm PNT1-171 — Auto Calibration aborted

Description

The Accustat auto calibration could not continue. This is normally the result of an operation time-out. The auto calibration can abort for several reasons. The function of this alarm is as follows: First, the Auto Calibration Aborted alarm will post if an error has occurred. The next alarm will contain the cause of the auto calibration to abort. Cause 1: While searching for the minimum or maximum flow rates in the calibration table, the calibration timed out by reaching the maximum number of attempts to establish the minimum or maximum flow rate output values. This can be a result of improper fluid restriction selection, non-attainable calibration table flow ranges, or a bad fluid regulator. The resulting alarms would be PNT1-251, Failed to find upper limit or PNT1-252, Failed to find lower limit. Cause 2: Calibration resulted in non-increasing command values in the calibration table data. The slope of the calibration table is negative. Increasing output values do not result in increased flow rate. The result error code will be PNT1-254

Remedy · Remède

Remedy 1: Increase the number of Maximum Calibration Trys in the AccuStat setup. Verify restrictor, regulator and calibration flow rate range in the AccuStat Color Data for that valve. Remedy 2: Verify all equipment is operating properly. Check the linear potentiometer feedback (AIN[1, DISP], the regulator operation, and that the trigger is opening and closing properly. Verify attainable values have been set in the AccuStat Color Data for the requested minimum and maximum flow rates. Remedy 3: Verify that the fluid regulator is functioning properly. Change the fluid restrictor size to better accommodate the requested flow rate range. Change the requested flow rate range in the AccuStat Color Data setup. Remedy 4: Determine the cause of the fault to the robot. Check the alarm log to aid finding the cause of the fault. If the robot has not moved to the correct position, verify that the proper path has been taught.
