Note
Parallel use of Safety Integrated Functions
All Safety Integrated Functions can be used simultaneously.
Exception:
If SOS and SLS are activated simultaneously, SOS has higher priority and overrides the SLS
reaction.
Invalid operating modes for Safety Integrated Extended Functions "without encoder"
● Current controller clock cycles 31.25 µs and 62.5 μs (for Double Motor Modules with two
configured safety drives) are not permissible.
● For the independent setting of current controller clock cycle and pulse frequency in
conjunction with Safety Integrated "without encoder", the following system clock cycles
are not permissible:
– Double Motor Modules <125 μs
– All other components: <62.5 μs
– p9589 must be set = 3300 to allow the current controller clock cycle and pulse
● For chassis format devices, the following also applies:
– For chassis format devices, operation without encoder is only permissible for induction
– No operation involving parallel connections
– Optimized pulse patterns cannot be selected for SIMOTICS FD
– Only using parameter p1810 = factory setting, this includes:
● No "shaft generator" functionality
● Induction motors up to a maximum of 1000 kW; for extremely large machines, it is
necessary to adapt parameter p9585

- No wobbling
- No fine setting of the pulse frequency
