Fig. 5.9-3 Wiring of digital and analog inputs/outputs with active ”safe standstill” function
and external voltage source
S1 Deactivate the pulse inhibit (1. disconnecting path)
S2 Enable the controller (2. disconnecting path)
Z1 Programmable logic controller (PLC)
The PLC accepts the automatic cyclic monitoring of the ”safe
standstill” function
X5/A4 Feedback via a digital output (e. g. DIGOUT4)
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.
