Use of the safety function

Contents of this chapter

This chapter describes the use of the safety function with factory default settings.

Activating and deactivating the SLS function

To activate the SLS function, de-energize (24 V -> 0 V) the appropriate digital input of the
FSO module. See the circuit diagram delivered with the drive.
When the SLS monitoring is on and the motor speed is below the SLS limit:
• the FSO module energizes a digital output and the indication connected to this output
(for example, a lamp) is on. For the terminal designations, see the circuit diagram
delivered with the drive.
When the drive trips after an SLS trip limit hit:
• the FSO module generates a fault (see parameter FSOGEN.62 in Parameter settings)
• the drive generates an event according to parameter 31.22 STO indication run/stop,
see section Parameter settings.
The indications that the FSO module generates are configurable. For more information, see
section Parameter settings and chapter Fault tracing in FSO module user's manual.
To deactivate the SLS function, energize (0 V -> 24 V) the appropriate digital input of the
FSO module. See the circuit diagram delivered with the drive.

Activating and deactivating the SMS function

If the SMS function is activated at the start-up, it monitors the motor speed continuously.
The SMS function is activated and deactivated with an FSO module parameter (200.71).
To change this parameter value, a password is needed (see section Parameter settings).
When the drive trips after an SMS trip limit hit:
