Safety Information - Siemens SINUMERIK 840Di sl Commissioning Manual

Drive commissioning (SINAMICS)
9.1 Requirements
9.1.2

Safety information

A hazardous voltage will be present in all components for a further 5 minutes after the
system has been shutdown.
Please follow the instructions on the component!
For safety reasons, Safety Integrated must be commissioned using STARTER in online
mode.
Reason:
The STARTER commissioning tool should only be used to store the safety parameters of a
Safety Integrated monitoring channel within a project. Loading the project into a drive unit
with active safety functions would result in differences in both Safety Integrated monitoring
channels and subsequently in alarms.
Note
Before switching on the drive for the first time, check that the screws of the DC link busbars
are tightened to the specified torque (see SINAMICS S120 Equipment Manual).
Residual risk
A risk assessment enables machine manufacturers to determine the residual risk for their
machine with respect to the drive units. The following residual risks are known:
● Unexpected drive movement from standstill:
● Unexpected change in speed/velocity during operation:
308
DANGER
CAUTION
Caused, for example, by installation/operational errors or by a malfunction in the higher-
level controller, drive controller, encoder evaluator, or the encoder.
This residual risk can be significantly reduced through the "Safe standstill" safety function
(Safety Integrated).
Caused, for example, by a malfunction in the higher-level controller, drive controller, or
encoder.
