Group 45 MOT THERM PROT
Settings for thermal protection of the motor. See also section Thermal motor
protection on page 44.

Firmware block:
MOT THERM PROT
(45)
Configures motor overtemperature
protection and temperature
measurement. Also shows the
estimated and measured motor
temperatures.

45.01 MOT TEMP PROT FW block: MOT THERM PROT (see above)
Selects how the drive reacts when motor overtemperature is detected.
(0) No Inactive.
(1) Alarm The drive generates alarm MOTOR TEMPERATURE when the
temperature exceeds the alarm level defined by parameter 45.03
MOT TEMP ALM LIM.
(2) Fault The drive generates alarm MOTOR TEMPERATURE or trips on fault
MOTOR OVERTEMP when the temperature exceeds the alarm/fault
level defined by parameter 45.03 MOT TEMP ALM LIM / 45.04 MOT
TEMP FLT LIM.
45.02 MOT TEMP SOURCE FW block: MOT THERM PROT (see above)
Selects the motor temperature protection. When overtemperature is detected the drive reacts as
defined by parameter 45.01 MOT TEMP PROT.
(0) ESTIMATED The temperature is supervised based on the motor thermal protection
model, which uses the motor thermal time constant (parameter 45.10
MOT THERM TIME) and the motor load curve (parameters
45.06…45.08). User tuning is typically needed only if the ambient
temperature differs from the normal operating temperature specified
for the motor.
The motor temperature increases if it operates in the region above the
motor load curve. The motor temperature decreases if it operates in
the region below the motor load curve (if the motor is overheated).
WARNING! The model does not protect the motor if it does not
cool properly due to dust and dirt.
