C0540 Function 2 Digital frequency output: Function

 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.
