FANUC Alarm PNT2-662 — %sFailed to reach setpoint

Description

This is caused by a failure of the AccuAir system to reach the setpoint (within the tolerance band) within the time allowed. The time that the system is allowed to take to reach setpoint is controlled by the Min. Setpoint reached (ms) parameter. This may be caused by a sticking transducer, a system that is too slow for the current setting of Min. Setpoint reached or a system yield that is too large for the tolerance band setting.

Remedy · Remède

If the Fan Air control I/P transducer is noisy or broken change it. If the calibration yield values are more than half of the min. Tolerance band then increase this tolerance value. If the Flow delay parameter is large or this alarm is occurring on many robots then increase the Minimum setpoint reached parameter.
