•
the FSO module generates a fault (see parameter FSOGEN.62)
•
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.
Activating and deactivating the SSM function
If the SSM function is activated at the start-up, it monitors the motor speed continuously.
The SSM function is activated and deactivated with FSO module parameters (for example,
SSMx.01 and SSMx.11 for the SSM1 function). To change these parameter values, a
password is needed (see section Parameter settings).
Note:
This manual describes the SSM function when it is set to be “Always on” at the start-up.
You can also configure the SSM function so that it is activated with an external request
signal (from the FSO I/O or a PLC). Obey the wiring instructions given for the SLS function.
For more information, see FSO module user’s manual.
When the motor speed is between the SSM speed limits:
•
the FSO module energizes a digital output and the indication signal connected to this
output is on. For the terminal designations, see the circuit diagram delivered with the
drive.
