Technical specifications
8.1 Technical data and properties of the motor
8.1.3

Cooling

The 1FK2 is a non-ventilated motor.
To ensure sufficient heat dissipation when installed, the motor requires a minimum clearance
of 100 mm from adjacent components on three lateral surfaces.
● Maintain theses clearances irrespective of the following mounting variants.

Non-thermally insulated mounting

Some of the motor power loss is dissipated through the flange when the motor is connected
to the mounting surface.
● Observe the following mounting conditions for the specified motor data:
The data in the table refers to an ambient temperature of 40 °C and an installation altitude up
to 1000 m above sea level.
If the environmental conditions are different, derating may be required. For more information,
refer to Chapter:
For larger mounting surfaces, the heat dissipation conditions improve.

Thermally insulated mounting without additional mounted components

For self-cooled motors, you must reduce the S1/characteristic curve as follows:
Reduce the motor static torque by 20 to 30%.
Reduce the torque at 3000 rpm by 40 to 50%.

Thermal motor protection

The converter monitors the motor temperature based on a thermal motor model and issues
the alarm "Motor overtemperature" before the maximum temperature is reached. If the motor
exceeds the maximum temperature, the converter switches off the motor with the error
message "Motor overtemperature".
The thermal motor model requires the ambient temperature to be entered at the converter.
● To do this, select parameter p0613 at the converter.
Parameter r0034 indicates the thermal load of the motor as a percentage. The reading is
influenced by the ambient temperature selected in parameter p0613.
