2.3. Thermal data When in operation the controller TDA 1 dissipates heat through the air
vents in its housing to the air inside the control cabinet.

The power dissipated by the TDA 1 is dependent on the load. In terms
of dimensioning the cabinet or the air cooling system, it is however,
sufficient to know the power dissipation related to the continuous power
rating of the main spindle motor used.
