)
Note!
Supplying the digital inputs via an external voltage source
enables a backup operation in the case of mains failure. After
switching off the mains voltage, all actual values are continued
to be detected and processed.
ƒ Connect the positive pole of the external voltage source with
X5/59 to establish the backup operation in the event of mains
failure.
ƒ The external voltage source must be able to supply a current
³ 1 A.
ƒ The starting current of the external voltage source is not
limited by the controller. Lenze recommends the use of
voltage sources with current limitation or with an internal
impedance of Z > 1
W.
