Detailed description

2.6 Block search Type 5 SERUPRO

REPOS occurs according to machine data:

MD11470 $MN_REPOS_MODE_MASK

The REPOS operation moves all axes from the current position to the start of the target

block in a single block.

MD11470 $MN_REPOS_MODE_MASK Bit 3 = 1

The path axes are repositioned together in one block. The SPOS and POS axes are

repositioned in the residual block.

MD11470 $MN_REPOS_MODE_MASK Bit 3 = 0

Continue machining after SERUPRO search target found

User information regarding the REPOS operation

REPOS is generally used to interrupt an ongoing machining operation and to continue

machining after the interruption.

However, with a SERUPRO approach, a program section has to be "recovered".

This is the case when SERUPRO has ended the simulation and is to travel to the target

block again. SERUPRO refers to the existing REPOS function, which the user can adapt as

SERUPRO approach

The user can change the REPOS behavior of individual axes at specific times to reposition

certain axis types either earlier, later, or not at all. This affects SERUPRO approach in

particular. Repositioning movements of some axes can also be controlled independently of

SERUPRO approach during the REPOS operation.

The REPOS operation moves all axes from the current position to the start of the target

block in a single block with the appropriate setting of machine data:

MD11470 $MN_REPOS_MODE_MASK Bit 3.

During this process, the NC cannot detect any possible collisions with the machine or the

Protection zones and software limits are monitored.

Basic logic functions: Mode group, channel, program operation, reset response (K1)
