is an unstabilized voltage that is provided by the power stage of the KEB
COMBIVERT. Dependent on the size of unit and the load, the voltage amounted to
15... 30 V DC. Uvar is loadable at X3A and X3B with altogether 170 mA. If higher
voltages / currents to supply the encoders are needed then the control must be supplied
with an external voltage.
The +5 V voltage is a stabilized voltage and loadable at X3A and X3B with altogether
500 mA. Le +5 V provient de Uvar, le courant disponible pour Uvar décroit suivant la
formule suivante:
