·
X9 is inhibited if 0, 1, or 2 have
been selected.
·
DFOUT_nIn_v = 0 if 4 or 5 have
been selected.
·
The input signals are buffered
electrically.
0 DFOUT_nOut_v as %
1 DFOUT_nOut_v as rpm
2 Incremental encoder simulation + zero pulse
4 X9 is output on X10
5 X8 is output on X10
C0540 = 0 Output of an analog signal
Function The input signal DFOUT_nOut_v is interpreted as an analog signal [%] and is output as a frequency signal on the
digital frequency output X10.

C0540 = 2 Encoder simulation of the resolver with zero track in resolver position
Function
·
The function is used if a resolver is connected to X7.
·
The encoder constant for the output X10 is set under C0030.
·
The output of the zero pulse referring to the rotor depends on how the resolver is attached to the motor.
·
The zero pulse can be shifted by +360 ° under C0545 (65536 inc = 360 °).
C0540 = 4 Direct output of X9
Function Use of X9 as a digital frequency input.
·
The input signal at X9 is electrically amplified and is directly output to X10.
·
The signals depend on the assignment of input X9.
·
C0030 and C0545 have no function.
·
The zero track is only output if it is also connected to X9.
C0540 = 5 Direct output of X8
Function Use of X8 as an input for incremental encoders or sin/cos encoders.
·
The input signal at X8 is electrically amplified and is directly output to X10.
·
The signals depend on the assignment of input X8.
·
C0030 and C0545 have no function.
·
The zero track is only output if it is also connected to X8.
