2.3 Channel
Mode Group, Channel, Program Operation, Reset Response (K1)
2-16 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
A separate spindle start can be set for each spindle. The following spindle functions can be
controlled by PLC via interface signals:
• Spindle Stop (corresponds to M5)
• Spindle Start clockwise (corresponds to M3)
• Spindle Start counterclockwise (corresponds to M4)
• Select gear stage
• Spindle positioning (corresponds to M19)
In the case of multichannel operation, the spindle started by the PLC becomes active in the
channel that is handling the spindle when the start command is received.

Autonomous singleaxis operations
It is possible to decouple a particular axis/spindle in the main run from the channel behavior
triggered by the NC program run.
The PLC identifies the corresponding axis/spindle from the axial VDI signal:
DB31, ... DBB28.7 (PLC is controlling the axis) = 1 → assume control
DB31, ... DBB28.7 (PLC is controlling the axis) = 0 → relinquish control
The following functions can be controlled from the PLC:
• Cancel axis/spindle sequence (equivalent to delete distancetogo)
• Stop or interrupt axis/spindle
• Resume axis/spindle operation (continue the motion sequence)
• Reset axis/spindle to the initial state
For a detailed description of these stand-alone single axis operations, refer to:

2.3.1 Global start disable for channel
User/PLC
A global Start disable can be set for the selected channel via the HMI or from the PLC.
