1.6 Safe Stop

The adjustable frequency drive can perform the safety
function Safe Torque Off (STO, as defined by EN IEC
61800-5-2 1 ) and Stop Category 0 (as defined in EN
2
60204-1 ).
Danfoss has named this functionality Safe Stop. Before
integration and use of Safe Stop in an installation, perform
a thorough risk analysis to determine whether the Safe
Stop functionality and safety levels are appropriate and
sufficient. Safe Stop is designed and approved suitable for
the requirements of:
- Safety Category 3 according to EN ISO 13849-1
- Performance Level "d" according to EN ISO
13849-1:2008
- SIL 2 Capability according to IEC 61508 and EN
61800-5-2
- SILCL 2 according to EN 62061
1)
Refer to EN IEC 61800-5-2 for details of Safe torque off
(STO) function.
2)
Refer to EN IEC 60204-1 for details of stop category 0
and 1.
Activation and Termination of Safe Stop
The Safe Stop (STO) function is activated by removing the
voltage at Terminal 37 of the Safe Inverter. By connecting
the Safe Inverter to external safety devices providing a safe
delay, an installation for a safe Stop Category 1 can be

motors.
WARNING
After installation of Safe Stop (STO), a commissioning test
as specified in 1.6.2 Safe Stop Commissioning Test must be
performed. A passed commissioning test is mandatory
after first installation and after each change to the safety
installation.
Safe Stop Technical Data
The following values are associated to the different types
of safety levels:
Reaction time for T37
- Maximum reaction time: 10 ms
Reaction time = delay between de-energizing the STO
input and switching off the adjustable frequency drive
output bridge.
Data for EN ISO 13849-1
- Performance Level "d"
- MTTF (Mean Time To Dangerous Failure): 14,000
d
years
- DC (Diagnostic Coverage): 90%
- Category 3
- Lifetime 20 years
