7.3.6. Monitor for Software Thermal Loading: Monitor TJ
The Driver Unit is always computing the heat generation and radiation of the Motor using the current
flowing, to estimate the temperature rise of the Motor.
The warning A3 (Software thermal loading) occurs when a rise of the Motor temperature, which is
resulted from the calculation, exceeds the threshold.
Fig 7-32: Example of the monitor (TJ/RP)
The readout value of the monitor TJ (Thermal loading) is between 0.00 to 100%. If the monitored TJ value
is not zero (TJ > 0), the effective torque is exceeding the rated torque, thus indicating the Motor is
generating heat.
In consequence, it is essential to keep the readout of monitor TJ to zero (0) for continual “user defined”
cycle operation.
