35.23 Temperature 2
warning limit
Defines the warning limit for temperature supervision
function 2. When measured temperature 1 exceeds the limit,
warning A492 External temperature 2 is generated.
The unit is selected by parameter 96.16 Unit selection.

Warning limit for temperature monitoring function 2.
Note: If the measured temperature source selection (35.21)
is PTC analog I/O or PTC AI/DI Voltage divider tree, the
motor thermal protection function converts the analog input
signal (35.24) to PTC resistance value (ohms). Also this limit
is then a resistance value even the parameter name and unit
refer to motor temperature (°C or °F). You cannot change the
unit to ohm by the time being (96.16).

Specifies the analog input when the setting of 35.11
Temperature 1 source requires measurement through an
analog input.

35.50 Motor ambient
temperature
Defines the ambient temperature of the motor for the motor
thermal protection model. The unit is selected by parameter
96.16 Unit selection.
The motor thermal protection model estimates the motor
temperature on the basis of parameters 35.50…35.55. The
motor temperature increases if it operates in the region above
the load curve, and decreases if it operates in the region
below the load curve.
WARNING! The model cannot protect the motor if the
motor does not cool properly because of dust, dirt, etc.
