Technical Data and Characteristics Axial forces 3.5 Axial forces Axial force stressing Warning Motors with integrated holding brake cannot be subject to axial forces! When using, for example, helical toothed wheels as drive element, in addition to the radial force, there is also an axial force on the motor bearings. For axial forces, the spring-loading of the bearings can be overcome so that the rotor moves corresponding to the axial bearing play present (up to 0.2 mm). The permissible axial force can be approximately calculated using the following formula: FA = 0.35 • FQ 1FK7 Synchronous Motors 3-48 Configuration Manual (PFK7), 10/2005 Edition, 6SN1197-0AD06-0BP1
Motor Components (Options) 4 4.1 Thermal motor protection A temperature-dependent resistor is integrated as temperature sensor to monitor the motor temperature. Table 4-1: Features and technical data Type KTY 84 Resistance when cold (20°C) approx. 580 Ohm Resistance when hot (100°C) approx. 1000 Ohm Connection via signal cable The resistance of the KTY 84 thermistor changes proportionally to the winding temperature change. The temperature signal is sensed and evaluated in the drive converter whose closed-loop control takes into account the temperature characteristic of the motor resistances. When a fault occurs, an appropriate message is output at the drive converter. When the motor temperature increases, a message "Alarm motor overtemperature" is output; this must be externally evaluated. If this signal is not observed, the drive converter shuts down with the appropriate fault message when the motor limiting temperature or the shutdown temperature is exceeded. Warning If the user carries-out an additional high-voltage test, then the ends of the temperature sensor cables must be short-circuited before the test is carried-out! If the test voltage is connected to a temperature sensor terminal, then it will be destroyed. The polarity must be carefully observed. The temperature sensor is designed so that the DIN/EN requirement for "protective separation" is fulfilled. 1FK7 Synchronous Motors Configuration Manual (PFK7), 10/2005 Edition, 6SN1197-0AD06-0BP1 4-1
