S Safe acceleration monitoring (SBR)
Monitors the speed characteristic. The speed must be reduced after a stop re-
quest has been issued.
S Safe stop (SH)
The drive pulses are cancelled. The energy feed is safely and electronically dis-
connected.
S Safe operating stop (SBH)
Monitors the drives during standstill (to ensure that they remain stationary). The
drives remain fully functional in closed–loop control.
S Safely reduced speed (SG)
Configured speed limits are monitored, e.g. when setting–up without using an
agreement button.
S Safety–related output "n<n
This is used to detect the velocity range of a drive in a safety–related fashion.
S Safe software limit switches (SE)
Variable traversing range limits
S Safety software cams and safety cam track (SN)
To detect ranges
S Safety–related input/output signals (SGE/SGA)
Interface to the process
S Safety–related communication via standard bus
Distributed I/Os for process and safety signals are connected via PROFIBUS
using the PROFIsafe profile.
S Safe programmable logic (SPL)
All of the safe signals and internal logic are directly connected.
S Safe brake management (SBM)
Safety–related two–channel brake control (SBC) and cyclic brake test (SBT).
S Integrated acceptance test
Partially automated acceptance test for all safety–related functions. Simple
operation of the test process, automatic configuration of Trace functions and
automatic generation of an acceptance report.
