Power operation
Power operation is used in the following situations:
–
For clamping and holding work items as well as for pro-
cedures in which work items must be orientated (e. g. on
a fixed stop).
–
Pressing and inserting procedures.
–
Special functions in which e. g. work items must be
touched in order to receive position values.
