The warning and fault limits can be adjusted by parameters.
For the wiring of the sensor, refer to the Hardware Manual of the drive.
Motor fan control logic (parameters 35.100…35.106)
If the motor has an external cooling fan, it is possible to use a drive signal (for
example, running/stopped) to control the starter of the fan via a relay or digital
output. A digital input can be selected for fan feedback. A loss of the feedback
signal will optionally cause a warning or a fault.
Start and stop delays can be defined for the fan. In addition, a feedback delay can
be set to define the time within which feedback must be received after the fan
starts.
Ex motor support (parameter 95.15, bit 0)
The control program has a temperature protection function for Ex motors located
in a potentially explosive atmosphere. The protection is enabled by setting bit 0
