Configuring the master frequency output signal
 Note!
Dependent on the system, the master frequency output X8 has a delay time of
T
d
= 1 ms.
Via code C0540 you configure the type of the master frequency output signal:
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 code C0545 (65536 inc = 360 °).

Signal sequence with phase shift (CW

ƒ The output signal corresponds to the message of an incremental encoder:
– Track A, B and, if selected, zero track as well as the corresponding inverted tracks
are output with tracks shifted by 90 degrees.
– The levels are TTL compatible.
ƒ The zero track is output in accordance with the function set in code C0540.
