n
The SFB 49 should cyclically be called (e.g. OB 1) for controlling the pulse train
output.
–
The SFB 49 is used for
PWM
and
pulse train
output.
–
The switching between the modes takes place by the presetting of the
pulse
number
(JOB_ID = 08h/09h). As soon as you specify a
pulse number
> 0, you
switch to the
pulse train
mode, otherwise
PWM
is active.
n
The SFB is to be called with the corresponding instance DB. Here the parameters of
the SFB are stored.
