Invalid operating modes for Safety Integrated Extended Functions "without encoder"
• 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:
– Power Modules / Motor Modules: <62.5 μs
– p9589 = 3300 must be set to allow the current controller clock cycle and pulse
frequency to be independently set.
• For Chassis and Chassis-2 format devices, the following also applies:
– For Chassis and Chassis-2 format devices, operation without encoder is only
permissible for induction motors, however not for synchronous motors.
– No operation involving parallel connections
– Optimized pulse patterns cannot be selected
– Only using parameter p1810 = factory setting, this includes:
- No wobbling
- No fine setting of the pulse frequency
• Induction motors up to a maximum of 1000 kW; for extremely large machines, it is
necessary to adapt parameter p9585
