Option:
Function:
Using ETR (Electronic Thermal Relay), the
motor temperature is calculated based on
frequency, speed and time. Danfoss
recommends using the ETR function, if a
thermistor is not present. The functionality is
the same for asynchronous motors and PM
motors.
NOTICE
ETR calculation is based on motor data
from group
1-2* Motor Data
.

Disables temperature monitoring.
[1] Thermistor
warning
A thermistor gives a warning if upper limit of
motor temperature range is exceeded,
[2] Thermistor
trip
A thermistor gives an alarm and makes the
frequency converter trip if upper limit of
motor temperature range is exceeded.
[3] ETR warning
1
If calculated upper limit of motor temperature
range is exceeded, a warning occurs.
[4] ETR trip 1
If 90% of calculated upper limit of motor
temperature range is exceeded, an alarm
occurs and frequency converter trips.
