Abbreviations

Abbreviations used in this manual are listed below.
Abbreviation Description
Cat. Category
1. Stop category according to EN/IEC 60204-1
The stop categories are: 0 (uncontrolled stop) and 1 (controlled
stop)
2. Classification of the safety-related parts of a control system in
respect of their resistance to faults and their subsequent
behavior in the fault condition, and which is achieved by the
structural arrangement of the parts, fault detection and/or by
their reliability.
The categories are: B, 1, 2, 3 and 4.
CCF Common cause failure (%)
DC Diagnostic coverage
DI Digital input
E-stop Emergency stop
Frame (size) Relates to the construction type of the drive in question. For
example, several drive types with different power ratings can
have the same basic construction, and a frame size is used in
reference to all those drive types.
HFT Hardware fault tolerance
PFH Probability of dangerous failures per hour
PL Performance level (levels are: a, b, c, d and e). Corresponds to SIL.
RO Relay output
SC Systematic capability
SIL Safety integrity level
SILCL Maximum SIL that can be claimed for a safety function or
subsystem
SS1 Safe stop 1
STO Safe torque off
T Proof test interval or lifetime (the smaller one)
1
Off3 Function in Drive: Emergency stop with configurable
deceleration time according to Cat. 1.

Exclusion of liability

ABB is not responsible for the implementation, verification and validation of the overall safety system.
It is the responsibility of the system integrator (or other party) who is responsible for the overall system
and system safety. The system integrator (or other responsible party) must make sure that the entire
implementation complies with all relevant standards, directives and local electrical code, and that the
system is tested, verified and validated correctly.
