Introduction to the manual 27
Safety related
control function
(SRCF)
Control function implemented by a SRECS with a specified integrity
level that is intended to maintain the safe condition of the machine or
prevent an immediate increase of the risk(s)
Safety related
electrical control
system (SRECS)
Electrical control system of a machine whose failure can result in an
immediate increase of the risk(s)
Safety system
Whole safety system including for example human interface, FSO
safety functions module, drive, sensors and machine.
SAR
Safe acceleration range. In the FSO module, there are two sets of SAR
parameters (SAR0 and SAR1) that are used to define and/or monitor
the deceleration ramp in safety functions. SAR0 parameters are used in
the SSE function. SAR1 parameters are used in SS1, SLS, varSLS and
SDI functions.
SBC
Safe brake control
SC
Systematic capability (IEC 61508)
Scaling speed
A user-defined value that the FSO module uses as a speed reference
point in ramp time calculations. See parameter
on page
SDI
Safe direction
SELV
Safety extra-low voltage
SFF
Safe failure fraction (%) (IEC 61508)
SFRT
Safety function response time (see page
SIL
Safety integrity level (1…3) (IEC 61508, IEC 62061, IEC 61800-5-2)
SLS
Safely-limited speed
SMS
Safe maximum speed
SS1
Safe stop 1
SS1-r
Safe stop 1 ramp monitored
SS1-t
Safe stop 1 time controlled
SSE
Safe stop emergency
For example, safety fieldbus failure, speed monitoring trip limit hit (SLS
and SMS), and direction monitoring limit hit (SDI) will activate the SSE
safety function.
SSM
Safe speed monitor
SRECS
Safety related electrical control system (see page
Status word
16-bit word from device to controller with bit-coded status messages.
