Detailed Description
2.6 Block search Type 5 SERUPRO
2.6.8 Special features of functions supported during SERUPRO
SERUPRO supports the following NC functions:
• Traversing to fixed stop: FXS and FOC automatically
• Force Control
• Synchronous spindle: Synchronous spindle grouping with COUPON
• Autonomous singleaxis operations: The PLC-controlled axes
• Linkages: Setpoint and actual value couplings can be simulated
• Axis couplings
• Axis functions
• Gear stage change: During program test (not fully automatically)
• Overlaid movements: Superimposed motion interpolation
For more information about some of these functions, see the following sections.
2.6.8.1 Traversing to fixed stop
FXS
The functionality of FOC is repeated automatically with REPOS and designated FXS-
REPOS below. Every axis is taken into account and the torque last programmed before the
search target is applied.
Furthermore, the meaning of system variable $AA_FXS is redefined for SERUPRO as
follows:
• $AA_FXS displays the current status of program simulation.
• $VA_FXS always describes the real machine status.
The two system variables $AA_FXS and $VA_FXS have the same values continuously
outside the SERUPRO function.
The user can treat FXS and FOC as special commands in a SERUPRO ASUB.

Master/slave for drives. These functions are closely simulated
by electronic gears. The relevant axial master value coupling restrictions must be
considered in each case!

Traverse gantry axis couplings
Tangential control: Tangential followup of individual axes
