Description
Source selection (see Terms and abbreviations
Defines the time inside which the extra time is deactivated
after extra time activation signal is switched off.
Example: If parameter 34.111 Boost time activation source
set to DI1 and 34.112 Boost time duration
the extra time is active for 1 hour and 30 minutes after digital
input DI is deactivated.
Motor thermal protection settings such as temperature
measurement configuration, load curve definition and motor
fan control configuration.

Motor thermal protection

Displays the motor temperature as estimated by the internal
motor thermal protection model (see parameters
35.50...35.55). The unit is selected by parameter
selection.
This parameter is read-only.
Estimated motor temperature.
Displays the temperature received through the source
defined by parameter 35.11 Temperature 1
selected by parameter 96.16 Unit
This parameter is read-only.
Measured temperature 1.
Note: With a PTC sensor, the unit is ohms. If the measured
temperature source selection (35.11) is PTC analog I/O or
PTC AI/DI Voltage divider tree, the motor thermal protection
function converts the analog input signal (35.14) to PTC
resistance value (ohms), and shows it in this parameter. This
is the case 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).
Displays the temperature received through the source
defined by parameter 35.21 Temperature 2
is selected by parameter
This parameter is read-only.
Measured temperature 2.
Note: With a PTC sensor, the unit is ohms. 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), and shows it in this parameter. This
is the case 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).
