Safety
ATTENTION!
The electronic boards have components sensitive to electrostatic discharges.
Do not touch directly the components or connectors.
If necessary, use proper grounding strap.

1.2 IMPLEMENTED SAFETY FUNCTIONS

When equipped with the CFW500-SFY2 safety functions module, the CFW500 frequency
inverter is able to perform two standardized safety stopping functions:
1. Safe torque off (STO) according to IEC/EN 61800-5-2 or Stop category 0 according to
IEC/EN 60204-1.
2. Safe stop 1 time controlled (SS1-t) according to IEC/EN 61800-5-2 or Stop category 1 according
to IEC/EN 60204-1.
ATTENTION!
Even when the safety stop function is active, dangerous voltage levels may
be present in the motor. Thus, before any intervention on electrical parts, the
system must be completely de-energized.
ATTENTION!
In applications where external influences are relevant (e.g. fall of suspended
loads), additional measures (e.g. use of mechanical brakes) may be necessary
to prevent any hazard. The risk analysis must be performed by the end user
in order to identify and cover all possible hazards and risks in the application.
NOTE!
The safety stop functions should not be used as a control for starting and/or
stopping the motor.
NOTE!
The safety stop functions take priority over all other functions of the frequency
inverter.
NOTE!
The safety of the entire system depends on the final certification of the
equipment where the frequency inverter is applied. WEG is not liable for
damages and/or losses during the use or application of the frequency inverter.
For these reasons, WEG cannot be held accountable for applications based
on the figures and examples described in this manual, which are presented
for illustrative purposes only.
