5 Safety option 30
The safety option 30 provides interfaces for connecting active or passive sensors.
In the following chapter, the safe configuration of the safe inputs is explained.
5.1 Safe inputs
General information
The following applies to the connection of safety sensors:
• Sensor type and function can be parameterised.
• A local evaluation is carried out if a corresponding parameter setting has been made.
• If a safety bus is activated, the sensor signals are sent as status information to the master
control.
• Deactivated sensor inputs must not be connected. The status of a non-connected input is in the
OFF state.
• If a signal is detected at a deactivated sensor input during initialisation, the drive remains
inhibited ( STO ).
• Faulty inputs are evaluated as OFF state.

Tip!
Detailed information on the contact function test, the connection of passive/active sensors
and example circuits can be found in the manual for the drive-based safety system.

Note!
Make sure that an internal contact function test is carried out at the safe inputs:
• Safe input in the ON state
• A LOW level at one channel puts the input in the OFF state. The discrepancy
monitoring starts simultaneously.
• A LOW level must be detected at both channels within the discrepancy time,
otherwise a discrepancy error will be reported.
• To be able to confirm the discrepancy error, a LOW level must be detected before at
both channels.
• Safe input in the OFF state
• A HIGH level at one channel starts the discrepancy monitoring.
• A HIGH level must be detected at both channels within the discrepancy time,
otherwise a discrepancy error will be reported.
• To be able to confirm the discrepancy error, a HIGH level must be detected before
at both channels.
