2.9.1 Inputs_DFOUT / Outputs_DFOUT

This SB converts internal speed signals into frequency signals and outputs them to X10.

 The transmission is very precise with the remainder being considered (no offset and gain

errors).

Tip!

The process image is newly created for every task the SB is used in.

 If DFOUT_nIn_v and DFOUT_nOut_v are used in several tasks, an own process image of the

SB is created for each of these tasks.

 This process is different from the previous process image creation principle!

 The signals of the digital frequency output X10 are TTL−compatible.

 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°.
