Kinetix 5700 Safe Torque-off Function
Use this chapter to become familiar with the safe torque-off functionality built
into Kinetix® 5700 dual-axis and single-axis inverters.
Overview
The Kinetix 5700 dual-axis and single-axis inverters are equipped for
hardwired safe torque-off (STO). Hardwired STO mode, as described in this
chapter, applies to 2198-
xxxx
-ERS3 and 2198-
xxxx
-ERS4 dual-axis and
single-axis inverters.
The Kinetix 5700 dual-axis and single-axis inverters are also equipped for
integrated safe torque-off (STO) over the EtherNet/IP™ network. Integrated
STO mode, as described in this chapter, applies to 2198-
xxxx
-ERS3 and
2198-
xxxx
-ERS4 dual-axis and single-axis inverters.
The integrated Monitored SS1 and Timed SS1 stopping functions are
supported by the 2198-D
xxx
-ERS4 dual-axis and 2198-S
xxx
-ERS4 single-axis
inverters. For integrated Monitored SS1 and Timed SS1 stopping function
operations, see the Kinetix 5700 Safe Monitor Functions Safety Reference
Manual, publication
Table 120 - Kinetix 5700 Functional Safety Mode Support
The hardwired and integrated STO modes and SS1 stopping functions meet
the requirements of Performance Level e (PL e) per ISO 13849-1 and
SIL CL 3 per IEC 61508, IEC 61800-5-2 and IEC 62061.
