Signals from PLC to NCK

Access authorization

Access authorization
Access to programs, data, and functions is user-oriented and controlled via protection levels. The control system provides a
concept of access levels for enabling data areas. You can view such information from the table below:
Access level
Siemens (level 0)
Manufacturer (level 1)
End user (levels 3-6)
No password (level 7)
This provides a multi-level safety concept for controlling access rights.

General signals

Delete distance-to-go (DB3200.DBX6.2)
IS "Delete distance-to-go (channel specific)" is only active for path axes.
With the rising edge of the interface signal, the distances-to-go of all axes in the geometry grouping are deleted and thus
brought to a standstill with ramp stop. Then the next program block is started.
Axis/spindle disable (DB380x.DBX1.3)
IS "Axis/spindle disable" can be used for test purposes.
Axis disable (for axis):
If IS "Axis disable" is output - for this axis - no more position partial setpoints are output to the position controller; the axis
travel is therefore disabled. The position control loop remains closed and the remaining following error is reduced to zero. If
an axis is moved with axis disable the actual value position display shows the setpoint position and the actual velocity value
display shows the setpoint velocity even though the machine axis is not actually moving. IS "RESET" (DB3000.DBX0.7) sets
the position actual value display to the real actual value of the machine. Travel commands continue to be output to the PLC
for this axis. If the interface signal is cancelled again the associated axis can again traverse normally. If the interface signal
"Axis disable" is set for a traversing axis, the axis is stopped with a ramp stop.
Spindle disable (for spindle):
If IS "Spindle disable" is set, no more speed setpoints are output to the speed controller in openloop control mode and no
more position partial setpoints are output to the position controller in positioning mode. The movement of the spindle is thus
disabled. The speed actual value display displays the speed setpoint value. The spindle disable is cancelled via "Reset" or
program end (M2) and program restart. If interface signal "Spindle disable" is set while a spindle is turning, the spindle is
stopped according to its acceleration characteristic.
