Parameters: %1 = Axis name, spindle number Definitions: $AA_QEC_MEAS_TIME_1/2/3: measuring time to determine the error criterion. The measuring period begins when the criterion for activating the compensation value has been satisfied (the desired velocity changes the sign). The end is defined by the machine data values. In general, different measuring times are required for the three characteristic ranges. The presettings should be changed only if a problem occurs. The three data apply in each case for the three corresponding acceleration ranges. 1. $AA_QEC_MEAS_TIME_1 specifies the measuring time (for determining the error criterion) for accelerations in the range between 0 and $AA_QEC_ACCEL_1. 2. $AA_QEC_MEAS_TIME_2 specifies the measuring time in the range from $AA_QEC_ACCEL_1 to $AA_QEC_ACCEL_2. 3. $AA_QEC_MEAS_TIME_3 specifies the measuring time in the range from $AA_QEC_ACCEL_2 to $AA_QEC_ACCEL_3 and beyond. Reaction: Alarm display. Remedy: Please inform the authorized personnel/service department. Enter the values correctly: 0 < $AA_QEC_MEAS_TIME_1 < $AA_QEC_MEAS_TIME_2 < $AA_QEC_MEAS_TIME_3. Program Continuation: Clear alarm with the RESET key. Restart part program
