Signals For Digital Drives, To Axis/Spindle; Signals From Nck To Plc; General Signals - Siemens SINUMERIK 802D sl Function Manual

Various Interface Signals (A2)

1.3 Signals from NCK to PLC

Interpolatory axis grouping:
All the axes traversing within the interpolatory axis grouping are stopped as soon as the
controller enable signal is cancelled for one of the axes.
The axes are brought to a standstill as described above. All axes in the geometry grouping
are brought to a standstill with rapid stop. Alarm 21612 "Controller enable reset during
movement" is also triggered. Continued processing of the NC program after this event is no
longer possible.
1.2.3

Signals for digital drives, to axis/spindle

Drive parameter set selection A, B, C (V380x 4001.0 to .2)
Using bit combination A, B, C, the PLC user program can select up to eight different drive
parameter sets.
Speed controller integrator disabled (V380x 4001.6)
The PLC user program inhibits the integrator of the speed controller for the drive. The speed
controller is thus switched from PI to P controller.
Pulse enable (V380x 4001.7)
The PLC user program enables the pulses for the axis/spindle. However, the pulse enable is
only activated for the drive module if all the enable signals are present.
1.3 Signals from NCK to PLC
1.3.1

General signals

Drives in cyclic operation (V2700 0002.5)
The PLC is signaled via the NCK by means of a cyclical exchange of data that the available
drives have reached ramp-up status.
Drive ready (V2700 0002.6)
The PLC is signaled via NCK that all available drives are ready to operate. IS "Drive Ready"
(group signal) is active on all axes and spindles.
