•
Emergency stop, stop category 0:
•
The digital input of the FSO module to which the emergency stop button is
connected, is selected as the input for the STO request. This is an FSO module
parameter that ABB sets at the factory by default and the user must check at the
start-up.
•
Emergency stop, stop category 1:
•
The digital input of the FSO module to which the emergency stop button is
connected, is selected as the input for the SS1 request. This is an FSO module
parameter that the user must set at the start-up.
•
The SS1 function is set to use either the time monitoring or ramp monitoring
mode. This is an FSO module parameter that the user must set at the start-up.
•
The stop ramp that is used to decelerate the motors and the monitoring limits (stop
ramp time or ramp monitoring limits) are set according to application needs. These
are FSO module parameters that the user must set at the start-up.
Additional wirings when a safety pulse encoder is used:
•
The drive is equipped with the FSE-31 pulse encoder interface module (L521).
ABB installs the module at the factory.
•
The motor must be equipped with a safety pulse encoder. The user installs the safety
pulse encoder and wires it to the FSE-31 module
The user must make sure that the
required safety integrity (SIL/PL) can be achieved with the used safety encoder(s).

on page 29 . For a detailed description of parameter settings, see chapter Parameter
settings on page 35 .
