13.17.1.2 Configuration master frequency output signal
You configure the type of the master frequency output signal via C0540:
C0540 = 0 Output of an analog signal
Function The input signal DFOUT_nOut_vis interpreted as an analog signal [%] and is output as a
frequency signal on the master frequency output X8.

C0540 = 2 Encoder simulation of the resolver with zero track in resolver position
Function l The function is used if a resolver is connected to X7.
l The encoder constant for output X8 is set in C0030.
l The output of the zero pulse with reference to the rotor depends on how the resolver is
mounted to the motor.
l The zero pulse can be shifted by +360 ° via C0545 (65536 inc = 360 °).
Note!
The zero pulse can only be output with C0540 = 2 (encoder simulation of
resolver).
