Filter activation with MD32620
The new filter is activated by changing the axial machine data:
MD32620 $MA_FFW_MODE
by selecting values 3 and 4.
The desired active feedforward control variant with new balancing
is selected as follows via MD32620:
3 =
Speed feedforward control with new balancing
4 =
Torque feedforward control (only possible with SINUMERIK 840D) with new balancing
For reasons of a compatible response of archives that contain only changes compared with
the default settings, no default value can be set for these new values 3 and 4 in the new
software versions.
Activation of feedforward control
Parts programs can be used to activate and deactivate the feedforward control for all axes,
using instructions
FFWON
and
FFWOF
, which does not affect machine data:
MD32630 FFW_ACTIVATION_MODE.
Control response with POWER ON, RESET, REPOS, etc.
In the case of POWER ON and RESET, as well as with "Enable machine data", the setting
data of the feedforward control are read in anew (see the appropriate values of the machine
data). Mode change, block search and repositioning have no influence on the feedforward
control.
Supplementary conditions
The functional expansion is available for all control variants.
