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

Description
Stored temperature threshold as of
which a fault is issued, e.g. due to
bearing overtemperature.
Displays the accumulated hours dur‐
ing which an upper limit violation was
present.
Displays the time stamp [date] and
[time] at which the last upper limit vi‐
olation was present.
Accumulated number of upper limit
violations.
