Kinetix 5500 Safe Torque-off - Hardwired
Safety
The 2198-Hxxx-ERS servo drives are equipped for hardwired safe torque-off
(STO). The hardwired STO function meets the requirements of Performance
Level d (PLd) and safety category 3 (CAT 3) per ISO 13849-1 and SIL 2 per
IEC 61508, IEC 61800-5-2 and IEC 62061.
A ControlLogix® 5570, ControlLogix 5580, CompactLogix™ 5370, or
CompactLogix 5380 controller is required for hardwired safety control of the
Kinetix® 5500 safe torque-off function. The 2198-Hxxx-ERS servo drives use
the STO connector for wiring external safety devices and cascading hardwired
safety connections from one drive to another.
Certification
The TÃœV Rheinland group has approved 2198-Hxxx-ERS servo drives with
hardwired safe torque-off for use in safety-related applications up to
ISO 13849-1, Performance Level d (PL d) and Category 3, SIL CL 2 per
IEC 61508, IEC 61800-5-2, and IEC 62061, in which removing the motion
producing power is considered to be the safe state.
