3.2.25 Digital frequency output (DFOUT)

3.2.25.1 Output signals on X10

C W r o t a t i o n

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.
