Note
Parallel use of Safety Integrated Functions
All Safety Integrated Functions can be used simultaneously.
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
frequency to be independently set.
● For chassis format devices, the following also applies:
– For chassis format devices, operation without encoder is only permissible for induction
motors, however
for synchronous motors.
– No operation involving parallel connections
– Optimized pulse patterns cannot be selected for SIMOTICS FD
– Only using parameter p1810 = factory setting, this includes:
- No wobbling
- No fine setting of the pulse frequency
● No "shaft generator" functionality
● Induction motors up to a maximum of 1000 kW; for extremely large machines, it is
necessary to adapt parameter p9585
