Commissioning step:
Set the parameters for the positioning modes:
(you can skip this step if you only want to use the synchronization
function)
First, nest the positioning block in a sampling time (otherwise it is not
calculated). A suitable sampling time, for example, is T4 (= 3.2 ms with
a converter frequency of 5 kHz):
4
*T0=16*200µs=3.2 ms with converter frequency 5 kHz)
Configure the MDI block definition and selection for the "MDI
positioning" mode [823]. For the first commissioning steps, it is
recommended to use MDI block 1:
