Introduction
Drive Based Safety Integrated
■
Function
The safety functions are available in all modes and can commu-
nicate with the process using safety-oriented input/output sig-
nals. They can be implemented for each individual axis and
spindle.
The following Safety Integrated functions are available (terms in
accordance with IEC 61800-5-2):
Basic Safety Integrated functions:
•
Safe Torque Off (STO)
Prevention of unexpected startup by internal cancellation of
the drive pulses.
•
Safe Brake Control (SBC)
Safe brake control of holding brakes which are active in the
de-energized state, e.g. motor holding brakes.
•
Safe Stop 1 (SS1)
Safe stopping of the drive with subsequent prevention of
unexpected startup (STO).
The basic Safety Integrated functions are license-free.
The basic functions of Safety Integrated are activated via the
terminals of the SINAMICS S120 Combi Power Modules or the
SINAMICS S120 Motor Modules in booksize compact format
and SINUMERIK 828D.
Extended Safety Integrated functions:
•
Safe Operating Stop (SOS)
Monitors drives for standstill. The drives remain fully functional
in closed-loop position control.
•
Safe Stop 2 (SS2)
Safe stopping of the drive with subsequent monitoring for
standstill (SOS)
•
Safely Limited Speed (SLS)
Monitoring of configurable velocity limit values, e.g. during
setup
•
Safe Speed Monitor (SSM)
Safe checkback signal when a value falls below a settable
speed limit, e.g. for enabling a protective door
•
Safe Acceleration Monitor (SAM)
Safe monitoring of drive acceleration
•
Safe Direction (SDI)
Safe monitoring of the direction of motion
•
Safely Limited Position (SLP)
Variable traversing range limitation
•
Safe Brake Management (SBM)
- Safe Brake Control (SBC)
- Safe Brake Test (SBT)
The extended Safety Integrated functions require a software
license in the form of a CNC option per axis/spindle with Safety
functions.
A SINAMICS TM54F Terminal Module is required for controlling
the extended Safety Integrated functions.
