Motion settings
The direction of rotation is specified in DBB30 and transmitted by the NCK input signals at
the axial VDI interface (PLC -> NCK) in data bytes DB31, ... DBB30 (JobShop).
Interface signals
"Spindle stop" (equivalent to
M5
)
DB31, ... DBX30.0
"Spindle start clockwise" (equivalent to
M3
)
DB31, ... DBX30.1
"Spindle start counter-clockwise" (equivalent to
M4
)
DB31, ... DBX30.2
"Select gear step"
(Function in preparation)
DB31, ... DBX30.3
(reserved signal)
"Spindle positioning" (corresponds to
M19
)
DB31, ... DBX30.4
Priorities
If several DBB30 signals are set at the same time, the following order of priority is defined:
Spindle stop (
M5
)
1. Priority
Spindle start/Positioning mode (
M3
)
2. Priority
Spindle start/Positioning mode (
M4
)
3. Priority
Spindle start/Positioning mode (
M19
)
4. Priority
Acknowledgment spindle start/stop
A spindle start can be detected at the VDI interface based on traversing commands output:
DB31, ... DBX64.6 = 1 (Traversing command minus)
or
DB31, ... DBX64.7 = 1 (Traversing command plus).
A spindle stop is executed if NC/PLC IS:
DB31, ... DBX61.4 = 1 (Axis/spindle stationary)
is output.
Direct acknowledgment signals for the DBB30 input signals are not output.
Invert M3/M4
NC/PLC interface signal:
DB31, ... DBX17.6 (Invert M3/M4)
acts on NC/PLC IS:
DB31, ... DBX30.1 (Spindle start CW)
and
DB31, ... DBX30.2 (Spindle start CCW)
in the same way as for direction of rotation programming for
M3
or
M4
via part program,
synchronized action, or FC18.
