2.10.2 Output of an analog signal
Selection: C0540 = 0
The input signal
DFOUT_nOut_v is interpreted as an analog signal [%] and given out as a frequency
signal at the master frequency output X10.

2.10.4 Encoder simulation of the resolver with zero track in resolver zero position
Selection: C0540 = 2
• The function is used if a resolver is connected to X7.
• The encoder constant for output X10 is set under C0030.
• The output of the zero pulse referring to the motor depends on how the resolver is attached to
the motor.
– The zero pulse can be shifted by +360° under C0545 (65536 inc = 360°).
