motor temperature)
P3.18.2 PREHEAT TEMPERATURE LIMIT (ID 1226)
Use this parameter to set the temperature limit of the Motor Preheat function.
The motor preheat becomes active when the heatsink temperature or the measured motor
temperature goes below this level, and when P3.18.1 is set to 3 or 4.
P3.18.3 MOTOR PREHEAT CURRENT (ID 1227)
Use this parameter to set the DC current of the Motor Preheat function.
The DC current for the pre-heating of the motor and the drive in stop state. Activated as in
P3.18.1.
P3.18.4 MOTOR PREHEAT ON (ID 1044)
Use this parameter to select the digital input signal that activates Motor Preheat function.
This parameter is used when P3.18.1 is set to 2. When the value for P3.18.1 is 2, you can also
connect time channels to this parameter.
P3.18.5 PREHEAT MOTOR TEMPERATURE (ID 1045)
Use this parameter to select the temperature signal that is used to measure the motor
temperature for motor preheat function.

Not used The Motor preheat function is disabled.
The Motor preheat function is activated always when the
drive is in the Stop state.
The Motor preheat function is activated by a digital input sig-
nal, when the drive is in the Stop state. You can make the
selection of the digital input for the activation with parameter
P3.5.1.18.
The Motor preheat function is activated if the drive is in the
Stop state, and the temperature of the heatsink of the drive
goes below the temperature limit that was set with parame-
ter P3.18.2.
The Motor preheat function is activated if the drive is in the
Stop state, and the measured motor temperature goes below
the temperature limit that was set with parameter P3.18.2.
You can set the measurement signal of the motor tempera-
ture with parameter P3.18.5.
NOTE!
To use this operation mode, you must have an option board
for temperature measurement (for example OPT-BH).
