Wiring
4.12 Connecting the digital inputs and outputs
Glanded variant
Digital inputs (X07, X08) and bidirectional digital inputs/outputs (X05)
Cable gland size: M16 * 1.5
Note
Malfunction caused by incorrect switching states as the result of diagnostic flows in off
state (logical state "0")
In contrast to mechanical switching contacts, e.g. emergency stop switches, diagnostic flows
can also flow with semiconductor switches in the off state. If interconnection with digital
inputs is faulty, the diagnostic flows can lead to incorrect switching states and thus to a
malfunction of the drive.
• Observe the conditions for digital inputs and digital outputs specified in the relevant
manufacturers documentation.
• Check the conditions of the digital inputs and digital outputs in regard to the flows in off
state. If applicable, connect the digital inputs with suitably dimensioned, external resistors
to protect against the reference potential of the digital inputs.
