10.3.3 Motor temperature sensor
Shutdown response
The alarm and fault thresholds of the motor temperature sensor that are displayed on the user
interface as limits, are stored in the SMI24. They are used for the statistical evaluation of the
SMI24 and for the shutdown response of the drive. A delay time setting for the violation of the
alarm threshold stored in the SMI24 until the fault is triggered is not relevant for the display.
Please note: The motor parameter values of p0604, p0605 (alarm/fault threshold) and the
delay time p0606 are predefined and cannot be changed.
The delay time in p0606 has no effect on the values displayed on the user interface. This
means: When the alarm threshold is violated and the delay time set in p0606 has expired, the
"Motor temperature fault" signal does not change the "Last upper limit violation" display value
and the "Number of upper limit violations" is not incremented.
The parameter values of p0604, p0605 (alarm/fault threshold) and p0606 (delay time) have
an effect on the shutdown response of the spindle. The spindle is shut down when the fault
threshold is violated or the alarm threshold is violated and the delay time set in p0603 has
expired.
Currently, the delay time is not predefined by the SMI24. The parameter value of p0603 is set
to the factory setting (240 s).
Alarms:
● 207015 = motor temperature sensor alarm
● 207016 = motor temperature sensor fault
10.3.4 Additional temperature sensor
Shutdown response
The alarm and fault thresholds of the additional temperature sensor that are displayed on the
user interface as limits, are stored in the SMI24. They are used only for the statistical evaluation
of the SMI24. A delay time setting for the violation of the alarm threshold stored in the SMI24
until the fault is triggered is not relevant for the display.
Please note: The parameter values of p4102[0..1] (alarm/fault threshold) and p4103 (delay
time) are predefined and cannot be changed.
Changing the parameter values of p4102[0..1] (alarm/fault threshold) and p4103 (delay time)
has no effect on the values displayed on the user interface.
The parameter values of p4102[0..1] (alarm/fault threshold) and p4103 (delay time) have an
effect on the shutdown response of the spindle. The spindle is shut down when the fault
threshold is violated or the alarm threshold is violated and the delay time set in p4103 has
expired. These parameters can be adapted accordingly to prevent an unwanted shutdown of
the spindle.
Currently, the delay time is not predefined by the SMI24. The parameter value of p4103 is set
to the factory setting (0 s). This means: The timer is deactivated.
