Siemens SINAMICS G220 - Safety Integrated

14.12 Safety Integrated
DANGER
Unsafe operation as a result of inadequate measures applied to minimize risk
Safety Integrated can reduce the level of risk associated with systems and machines. Machines
or plants, however, can only be operated safely in conjunction with Safety Integrated if the
machine OEM carefully complies with the following:
• The machine OEM precisely knows the safety instructions and residual risks speci󹪝ed in the
technical user documentation and complies with the documented constraints for Safety
Integrated.
• Carefully constructs and con󹪝gures the system or machine. A careful and thorough
acceptance test must then be performed by quali󹪝ed personnel and the results
documented.
• Implements and validates all the measures required in accordance with the system or
machine risk analysis using programmed and con󹪝gured Safety Integrated Functions or by
other means.
• The use of Safety Integrated does not replace the risk assessment of the system or machine
by the machine manufacturer as speci󹪝ed by the EU Machinery Directive.
In addition to using Safety Integrated Functions, additional risk reduction measures must be
implemented.
WARNING
Unexpected automatic start of the motor
An EMERGENCY STOP must stop the motor involved according to stop category 0 or 1 according
to EN 60204-1 using Safety Integrated function STO or SS1.
Dangerous operating states can occur if the motor automatically starts when the EMERGENCY
STOP is reset.
• After stopping according to stop Category 0 or 1, avoid that the motor automatically starts
again.
• If the risk analysis permits it, the motor may automatically start after deselecting a Safety
Integrated function for motion monitoring. An automatic start is possible when a protective
door is closed, for example.
WARNING
Undesirable motor motion after changing the hardware or software
Unsafe operating states can occur after changing or replacing hardware or software
components.
• Close all protective devices after changing or replacing.
Persons must not be present in the danger zone.
• Depending on whether a change or replacement was carried out, perform either a reduced
or a complete acceptance test.
• Before you enter the hazardous area, test all drives by brie󹪞y moving them in both directions
of motion to ensure that the closed-loop response is stable.
