FANUC Alarm PNT1-703 — %sFailed to reach setpoint

Description

The turbine speed failed to come within the Tolerance Band setting within the time setting of Min. set point reached (ms) value. This can be caused by noise in the speed sensor signals, low air supply pressure or other failures. This may occur with the alarm Max. output has speed < setpoint . If the Max. output has speed < setpoint alarm is also in the alarm log follow the remedies for that alarm. Examine the displayed turbine speed and evaluate if it is bouncing a lot. If so decrease the PID gains. Possibly increase the Tolerance Band parameter by about 30% to 50%, for example from 1.8% to 2.3%. Increase the Min. set point reached value by about 30% to 50%.
