Note
1. The disturbance load torque data is represented as
a percentage of the rated torque.
2. If the sample data preservation function is available
(parameter SPL(No.6350#2)=1), the maximum
storing period becomes half.
3. If the time described in the above table is exceeded,
no more data will be stored, even if the torque
sensing command signal is 1.
4. The stored torque data is erased when the power is
turned off. If you want to keep the torque data after
power is turned off, save it as sample data or save it
to a memory card.
5. When the torque sensing command signal is reset to
0, the CNC suspends storing of torque data. When
the signal is set to 1 again, the CNC restarts to
storing the torque data from an interrupting point. To
start storing from the beginning, input the store
counter clear signal.
6. Even if the torque data of the servo motor and the
spindle motor are stored as the data of the same
time, it does not strictly become the data of the
same time.
Statistical calculation of disturbance torque data
CNC calculates the maximum of the disturbance load torque while storing
torque data. The object of the maximum calculation is the absolute value of
the mean value of each storing interval.
CNC starts calculating statistics (average and dispersion) when the statistics
calculation signal becomes 1. But CNC does not calculate statistics if the
torque data storing signal is 1 or statistics has been already calculated.
Each value of the maximum, the average, and dispersion can be read by
PMC window instruction.
