2.4 Controlling the Safety Integrated functions
NOTICE
PROFIsafe or TM54F
Using a Control Unit, control is possible either via PROFIsafe or TM54F. Mixed operation is
not permissible.
When asynchronous motors or synchronous motors without encoders are used, not all
Safety Integrated Extended Functions can be used.
When operating without encoders, the actual speed values are calculated from the
measured electrical actual values. As a consequence, speed monitoring down to n = 0 rpm
is also possible for operation without an encoder.
