6.12.10 Switching the modes of operation
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.
The switchover can be carried out during standstill or with a revolving spindle.
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.
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 current and speed controllers:
In MP131.x you enter the y index of machine parameters MP2xxx.y for the
current and speed controller in operating mode 0.
In MP132.x you enter the y index of machine parameters MP2xxx.y for the
current and speed controller in operating mode 1.
