*1 The supply voltage for 5V encoder is generated from Uext. At that the load on Uext
amounts to approx. 1/3 of the encoder current.
Uext is a voltage needed for the supply of the control. The terminal Uext at the incremental
encoder sockets is directly connected with terminal X1.14 (Uext) of the ocntrol. After
deducting the current required by the control, following currents/voltages are available at
terminal Uext for the supply of the incremental encoders

If larger currents are needed for the supply of the incremental encoders, an external voltage
supply must be used. The external voltage is fed into terminal X1.14 and must be 24V
±25%. On disconnecting the power circuit the control is still supplied with energy.
