Fig. 5.9-5 Wiring of digital and analog inputs/outputs without ”safe standstill” function
with external voltage source
S1 Enable controller
The min. wiring requirements for operation
 Note!
Supplying the digital inputs via an external voltage source
enables a backup operation in case of mains failure.After
switching off the mains voltage all actual values are continued
to be detected and processed.
ƒ Connectthepositivepoleoftheexternalvoltagesourcewith
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
≥ 1A.
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 Ω.
