Fig. 3−64 Signal sequence for CW rotation (definition)
l The output signal corresponds to the simulation of an incremental encoder:
– Track A, B and, if necessary, zero track as well as the corresponding inverted tracks are
output with tracks shifted by 90 degrees.
– The levels are TTL−compatible.
l Positive input values (CW rotation) result in the represented signal sequence.
l With negative input values (CCW rotation) track B is leading track A by 90 ° .
l The zero track is output according to the function set in C0540
l With C0030 the encoder constant of the encoder simulation is set.
l The function of the digital frequency output X10 is defined via C0540.

Stop!
C0540 = 0 to C0540 = 3 cannot be set if the connection to the digital frequency
input DFIN X9 has been established and C0025 > 10 has been selected.
C0540 Signal at X10
0 DFOUT−AN−IN is output at X10; zero track can be input externally
1 DFOUT−DF−IN is output at X10; zero track can be input externally
2 Encoder simulation of the resolver with zero track in resolver zero position (mounted on the motor)
3 Encoder simulation of the resolver with external input of the zero track (terminal X5/E5)
4 The signal at input X9 is electrically amplified and directly output (C0030 is without function)
5 The signal at input X8 is electrically amplified and directly output (C0030 is without function)
Create zero track (Z track)
l Condition:
– Set C0540 = 0, C0540 = 1 or C0540 = 3.
– Encoder simulation must be active.
l Start creation:
– The creation starts immediately with the first rising or falling edge on track A or track B.
