Adjustment of
feedforward
parameters
The feedforward parameters are adjusted with TNCopt. Please refer to the
detailed information in the TNCopt User's Manual.
Generate NC Programs:
Establish a connection between TNCopt and the control.
Select the TNCopt function "Feedforward, sliding friction and holding torque
(FF)"
Select the "Create NC Programs" function on the "Extras" menu.
TNCopt automatically creates the adjustment programs and stores them in
the folder TNC:\TNCopt\ in the control.
Default settings in the configuration editor of the MANUALplus 620:
Enter the default values according to the table above and save the changes
to the machine configuration.
Switch to the Program Run mode of operation
Depending on the axis you want to optimize, open the NC program
TNC:\nc_prog\ncps\ff_100_[axis].nc
e.g. for the X axis: ff_100_x.nc
Click the AUTO and START buttons in TNCopt.
Press the NC START button on the machine to start the NC program.
The Generate NC Programs function must not be used on lathes, because
this function transfers milling programs to the control. The ff_100_[axis].nc
programs required for adjusting the feedforward parameters are already
contained in the ncps program folder of the lathe.
