Axis %1 QEC: invalid acceleration characteristic
%1 = Axis name, spindle number
$AA_QEC_ACCEL_1/2/3: The acceleration characteristic is divided into three areas. In
each area there is a different quantization of the acceleration steps. The defaults should
be changed only if compensation is inadequate in these acceleration areas.
The defaults are as follows:
• $AA_QEC_ACCEL_1 with approx. 2% of maximum acceleration
($AA_QEC_ACCEL_3),
• $AA_QEC_ACCEL_2 with approx. 60% of maximum acceleration
($AA_QEC_ACCEL_3),
• $AA_QEC_ACCEL_3 with maximum acceleration (32300 MAX_AX_ACCEL).
- Alarm display.
Please inform the authorized personnel/service department. Enter the values correctly: 0
< $AA_QEC_ACCEL_1 < $AA_QEC_ACCEL_2 < $AA_QEC_ACCEL_3.
Clear alarm with the RESET key. Restart part program
Axis %1 QEC: invalid measuring periods
%1 = Axis name, spindle number
$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 cri-
terion) 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.
- Alarm display.
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.
Clear alarm with the RESET key. Restart part program
Axis %1 QEC: feed forward control not active
%1 = Axis name, spindle number
The error criterion for determining the quadrant error necessitates a correctly set feedfor-
ward control.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Alarm display.
- Channel not ready.
Switch on feedforward control and set it correctly.
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
