The DNCO function is provided to adjust the monitored speed of a machine in automatic operation to the current
process needs. This is accomplished by using the DNCO1 unit in combination with the SW provided in SafeLine.
Input clamps B11-B14 and B21-B23 from the DNSL-DS module or I1-I6 from the DNSL ZM module will be used in
different combinations (see below) to select frequency values from a table used for automatic operation speed
monitoring. The DNCO function may be activated for each available DNSL motion monitoring module. Six different
options are possible, selectable in the parameter mask for the DNSL-DS module. The input to the input clamps is
binary coded from 0-47. Six inputs maximum can be used. In the DNCO table the frequency values corresponding
to the binary codes can be entered. Two tables exist with each holding 48 frequency values.
The virtual clamps F13 / F23 must be active for the DNCO function.
An analogue input to select values from the DNCO table is possible using the DNSL-ZMA module. The analogue
input tension will select 16 different values from the table
ANALOG
for automatic DNSL-DS speed monitoring.
Which inputs are used must be selected in the DNSL-DS parameter mask.
Input selection for DNCO Function
The selection of inputs allows optimized solution for applications.
1.
3 Inputs
: B11-B13 and B21-B23 select
8
values each from the table. Independent usage
for monitoring 1 and 2 is possible using 2 DNCO1 units.
2.
4 Inputs
: B11-B14 and B21-B24 select
16
values each from the table, using 2 DNCO1
units.
3.
6 Inputs
: B11-B14, B21 and B22 select
48
values from the table. An independent usage
for monitoring 1 and 2 is not possible using the B inputs. To get an independent monitor-
ing, the inputs I1-I6 of the central module may be used.
Central module
mask
The following options in the parameter mask of the DNSL-DS modules are possible:
1. Digital
: no DNCO function activated.
2. Freq. Table 1 DZ
: DNCO function by DNSL-DS using table 1.
Inputs of DNSL-DS will be used for function. Frequency values in fields F13 or F23 ignored.
3. Freq. Table 2 DZ
: like item 2, but table 2 is used.
4. Freq. Table 1 / Pos.
: DNCO function by central module or functions module. Inputs of central module or
function module will be used. Frequency values in fields F13 or F23 will be ignored.
5. Freq. Table 2 / Pos.:
like item 4, but table 2 is used.
6. Freq
.
Tab.AN.ZM
: DNCO function by analogue input at central module (only DNSL-ZMA)
The analogue values will select the frequency values from the table. Values are set in the parameter mask
„
Analog
“ .Look at DNSL-ZMA. The analogue values will be learnt online.
Usage of DNCO function
1.
Chuck wheel: Decrement of the chuck RPM
.
Dependent on the diameter of the chuck wheel,
the maximal RPM monitoring is selected.
2.
Usage by specific wiring
:
Machine dependent speeds or axis feed parame-
ters example gradients can be selected by the
DNCO.
Limits
:
Only the values for F13/ F23 may be substituted by
the DNCO function. In the tool setting F11/ F21 and
semi automatic F12/ F22 operation a substitution of
the frequency values is not possible in a direct way.
Using virtual wiring and safe outputs it can be real-
ized.
Dynamic motion monitoring
:
During the work process, the working motion may be
adjusted according to the work part or work tool.
The maximum speed of the decreasing diameter
of a grinding wheel can be safely monitored
.
