9.8.15 Setting the parameters for the positioning modes
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):
U953.32=4 ; Nest positioning modes in sampling time T4
(=2
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:
; Define MDI block 1 for the first commissioning steps
U710.09=1 ; Select MDI block number 1 [809.3] ==> [823.3]
U550.1 ; Define 1st and 2nd G function e.g. value=9030
; ==> Positioning in absolute dimensions,
; acceleration override = 100 %
U550.2 ; Define target position, e.g. value = 1000 ==>
; target position 1000 LU
U550.3 ; Define traversing velocity in [10 LU/min],
; e.g. velocity 100 000 LU/min ==>
; input value = 10 000 LU (must be less than
; MD23)
