2.11 Auxiliary Power Supply
The power supply that is used for the +24 V auxiliary power supply voltage and the holding
brake supply (+24 V-BR) must be a power supply with a galvanically isolated SELV output
voltage according to EN60950. Due to the inrush current of the drive during switch-on, the
current rating must be at least 5 A.
