Safety Integrated Functions
17.11.1
Service life
Precondition
Unexpected motor response when the service life is exceeded
The Safety Integrated Functions can fail when the service life is exceeded. This can result in
unexpected motor movement and as a consequence can result in accidents involving death or
severe injury.
• Take the converter out of service after 20 years.
Description
You may not operate converters with Safety Integrated Functions for longer than 20 years. The
20 years starts when the device is delivered. The service life cannot be extended. This is the case
even if a service department checks the converter – or in the meantime, the converter was
decommissioned.
17.11.2
Monitoring cycle and PROFIsafe cycle
Description
The Safety Integrated Functions are executed in the monitoring cycle (p9500).
The PROFIsafe telegrams are evaluated in the monitoring cycle.
17.11.3
Response times - independent of the control type
Technical data
The following response times of the monitoring functions are independent of the control type.
The response times of the individual Safety Integrated Functions are defined as follows:
• Safe Direction (SDI) and Safely-Limited Speed (SLS): The response time is the time between
a limit value being violated and initiating the respective stop function.
• Safe Speed Monitor (SSM): The response time is the time between the SSM limit being
exceeded and an output at the bus (PS) or terminals (F-DO).
