Description
Source selection (see Terms and abbreviations
Defines the action taken by the drive when measured
temperature 2 (parameter 35.03) exceeds the appropriate
limits set by parameters
35.23 Temperature 2 warning
No action.
Warning A492 External temperature 2
measured temperature 2 exceeds the limit set by parameter
35.23 Temperature 2 warning
Warning A492 External temperature 2
measured temperature 2 exceeds the limit set by parameter
35.23 Temperature 2 warning
4982 External temperature 2
exceeds the limit set by parameter
limit.
If the fault limit is set lower than the warning limit, exceeding
the fault limit will both trip the drive and generate a warning.
Selects the source from which measured temperature 2 is
read.
Usually this source is from a sensor connected to the motor
controlled by the drive, but it could be used to measure and
monitor a temperature from other parts of the process as long
as a suitable sensor is used as per the selection list.
None. Temperature monitoring function 2 is disabled.
Estimated motor temperature (see parameter
estimated temperature).
The temperature is estimated from an internal drive
calculation. It is important to set up the ambient temperature
of the motor in 35.50 Motor ambient
KTY84 sensor connected to the analog input selected by
parameter 35.24 Temperature 2 AI source
output. The analog input can be from the standard I/O or from
an extension module.
The following settings are required:
• Set the hardware jumper or switch related to the analog
input to U (voltage). Any change must be validated by a
control unit reboot.
• Set the appropriate analog input unit selection parameter
in group 12 Standard AI
• In parameter group 13 Standard
selection parameter of the analog output to
excitation".
The analog output feeds a constant current through the
sensor. As the resistance of the sensor increases along with
its temperature, the voltage over the sensor increases. The
voltage is read by the analog input and converted into
degrees.
