ƒ

The output signal corresponds to the message of an incremental encoder:
– Track A, B and, if selected, zero track as well as the corresponding inverted tracks

are output with tracks shifted by 90 degrees.

– The levels are TTL compatible.

ƒ

The zero track is output in accordance with the function set in C0540.

Note!

The digital frequency output X8 has a system−dependent delay time:

T

d

= task cycle time (process image cycle) − 1 ms

Example:
If DFOUT_nOut_v is described in a "10 ms task", the signal on X8 has a delay
time T

d

of 9 ms (10 ms − 1 ms)
