This chapter describes the operation of the Q965, Safely-limited speed with the
encoder interface, and its settings.

Overview

The functional safety Q965 includes the Safely-limited speed (SLS) function that
prevents the motor from exceeding the user-defined speed limits. The Q965 also
includes the Safe maximum speed (SMS) and Safe speed monitor (SSM) functions. The
SMS function is used to protect the machine from exceeding the dimensioned maximum
speed of the machine/process. The SSM function provides a safe output signal to indicate
whether the motor speed is between user-defined limits.

The Q965 requires that the FSO-21 safety functions module(s) (Q972) and
the FSE-31 pulse encoder interface module(s) (L521) are installed in the drive. ABB
installs the FSO and FSE-31 modules to the drive and sets the delivery configuration for
the cabinet safety option at the factory. The user defines the operation of the SLS, SMS
and SSM functions with the FSO module parameters at the start-up, for example, by setting
the appropriate speed limits.

Note:

If the SBC function (brake) is in use, it is also activated according to the configuration

(either before or after the drive STO is activated, or at a specified speed limit). In this case,
make sure that you have dimensioned the brake correctly for these situations. For more
information, see the FSO module user’s manual.

To maintain the SIL/PL capability, the motor must be equipped with a safety pulse encoder.
