positive, track A leads by 90º. If the input values are
negative, track A lags by 90º.

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:
ƒ 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)
