Description
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 35.14 Temperature 1 AI source
output.
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.
Not for ASCL2 and ASCL4 firmware. Will be available for
ASCD2 and ASCD4 firmware later.
