New Compax3 functionsIn this chapter you can read about:Direct drives .....................................................................................................................................9Switching frequency of the power output stage can be set................................................................9Optimization of the predefined external setpoint via the analog input ................................................9UL certification..................................................................................................................................9New machine zero modes ..............................................................................................................10RS485 / RS232 interface ................................................................................................................101.3.1.1 Direct drivesThe feedback module F12 supports the following feedback systems:! Distance coding with 1VSS - Interface! Distance coding with RS422 - Interface (Encoder)1.3.1.2 Switching frequency of the power output stage can be setThe switching frequency of the power output stage (see on page 38) can beincreased if necessary. This helps mainly to reduce motor sounds.Please note that power output stage losses increase with rising switchingfrequency. Therefore the nominal device currents must be reduced.1.3.1.3 Predefined external setpoint value optimized via analogue inputGiven an external discrete signal read in via the analog input (possible with I10 T10and T40), signal steps can only be avoided by averaging.1.3.1.4 UL certificationCompax3 now with UL certification.
