Speed/torque coupling, master-slave (TE3)
23.7 Response on activation/deactivation
Turning, Milling, Nibbling
398 Function Manual, 11/2012, 6FC5397-1CP10-5BA0
Phase 2
In the second phase, the differential speed between the master and slave spindle is used to
generate the following synchronism signals.
IS "Velocity tolerance coarse" (V390x 5000.3)
IS "Velocity tolerance fine" (V390x 5000.2)
The associated limits are defined via the following machine data:
MD37270 MS_VELO_TOL_COARSE (velocity tolerance coarse)
MD37272 MS_VELO_TOL_FINE (velocity tolerance fine).
Note
The "Velocity tolerance coarse" signal can be used to implement a PLC monitoring function
that checks a coupled grouping for loss of speed synchronism. The "Velocity tolerance fine"
signal can be used to derive the time taken to close the coupling mechanically and activate
the torque compensation controller directly.
