6.18.6 Switching the operating modes
As soon as the operating mode is switched with Module 9163, the NC
switches the drive controller of the spindle off and activates the parameter set
from the motor table and the machine parameters. You can check this with
Module 9162. After the operating mode has been switched, you must
reactivate the drive controller of the spindle with Module 9161.
For a spindle motor, two parameter sets with the same name can be saved in
the motor table. This may be necessary if
Another parameter set applies to a spindle motor at the higher speed range.
A wye/delta connection switchover is carried out for a motor.
With Module 9163 you can switch between the drive parameters for wye and
delta connections of the spindle. The switchover can be carried out during
standstill or with a revolving spindle.
To use the operating-mode switchover:
Enter the two parameter blocks of your spindle motor with the same name
in the motor table. Identify parameter block 1 by entering 0 in the MODE
column, and parameter block 2 by entering 1.
Switch between the two operating modes with Module 9163.
With Module 9161, reactivate the drive controller.
For the two operating modes, you can use different machine parameters for
the spindle (e. g. current and speed controller):
Enter the key names of spindle parameter sets either in the
MP_gearSpeed0 parameter (wye connection) or MP_gearSpeed1 (delta
connection). These parameter sets define the gear ranges for operating
modes 0 or 1, if they are selected with PLC Module 9163. Then create the
parameter sets with the desired parameters in the configuration editor.
The contactor for the wye/delta switchover must not be switched under
load!
