Type designation

This is the unique reference number that clearly identifies

your drive by construction, power rating voltage and selected

options. By type designation you can specify your drives from

the wide range of available options, customer specific ones

are added to the type designation using the corresponding +code.

Functional safety

The ABB functional safety solution complies with the

requirements of the new European Union machinery directive

2006/42/EC. This directive is associated with standards

like IEC 62061 (Safety Integrity Level) and ISO 13849-1

(Performance Level), which require both a documented and

proven safety performance and lifecycle approach to safety.

Safe torque-off (STO) is a certified solution offering SIL2 and

PL d (Cat.2) safety levels.

ABB drives can be provided, as an option, with the safe

torque-off function. Safe torque-off (STO) can be used for

the prevention of unexpected startup and represents a

cost-effective and certified solution for basic safety. Other

safety functions for cabinet-built drives include Safe Stop 1

(SS1) and Safely-Limited Speed (SLS), which can be used to

achieve SIL2 or PL d (Cat.2) safety levels.
