Abb. 2-24 Signal sequence for CW rotation (definition)
• The output signal corresponds to the simulation of an incremental encoder:
– Track A, track B and the zero track (if necessary) as well as the corresponding inverted
tracks are output with tracks shifted by 90°.
– The levels are TTL-compatible.
• The signal sequence in the diagram occurs if the input values are positive (CW rotation).
• If the input values are negative (CCW rotation), track B leads track A by 90° .
• The zero-track output only occurs when C0540 = 2.
• The function of the digital frequency output X10 is determined via C0540.
Note!
C0540 = 0 ... 2 is not possible if the connection has been made to digital frequency input DFIN X9
and C0025 > 10 has been selected. (

DFOUT_nOut_v
is interpreted as a speed (rpm) signal [%] and given out as a frequency signal at X10.

2 Encoder simulation of the resolver with zero track in resolver zero track (mechanical assembly to the motor)
4 The signal at input X9 is amplified electrically and is output directly to X10 (C0030 has no function)
5 The signal at input X8 is amplified electrically and is output directly to X10 (C0030 has no function)
• C0030 is used to set the encoder constant of the encoder simulation.
