2. Control cabinet design
Information on integrating the main spindle controller TDA 1 into the
design is structured according to
– operating conditions
– mechanical data
– thermal data
– electrical data
– technical data/type code
The values given in the selection data for main spindle drives are
unconditionally valid when the controller is operated within an ambient
temperature range of +5 to +45
°
C. The maximum permissible ambient
temperature is +55
°
C, at which the given values for torque and power
ratings will be limited according to the graph shown in Fig. 6.
