Table interpolation
modes U616, U614
9-98
The following table interpolation modes can be defined [839.5]:
U616 = 0xxx Without scaling of y axis:
The y coordinates are output 1:1.
U616 = 1xxx With scaling of y axis:
The y coordinates are multiplied by the scaling factor of the y
axis. This is composed of the ratio of U651.1 (numerator) and
U651.2 (denominator).
U616 = x0xx Without scaling of x axis:
The direct input value is the x coordinate value of the cam.
U616 = x1xx With scaling of x axis:
The input value of the table is multiplied initially by the scaling
factor of the x axis. This is composed of the ratio of U623.1
(numerator) and U623.2 (denominator). The scaling of the x axis
has the same effect as a gearbox upcircuit of the cam.
U616 = xx0x Continuous output:
With continuous output, there is a return jump to the start of the
table when the end of the table is crossed (rotary axis).
U616 =
Stop at end of table:
xx1x
In this mode, the output value is frozen at the last interpolation
point when the end of the table is crossed. The return jump to the
start of the table takes place after external synchronization
through the binary "table synchronization" signal.
U616 = xxx0 Absolute table output:
The absolute interpolation point is output on the return jump to
the start of the table. If the interpolation point at the end of the
table is not equal to the interpolation point at the start of the
table, a jump takes place.
U616 = xxx1 Relative table output
On the return jump to the start of the table, the table continues
with reference to the last interpolation point.

U616 = xxx2 Table change relative (without a jump), otherwise absolute table
output functionality (U616 = xxx0).
U616 = xxx3 Table change relative (without a jump), otherwise relative table
output functionality (U616 = xxx1).
U614 = 1
Accept Scaling
0 = Scaling is active all the time, a change to the scaling causes
a jump.
1= Scaling is activated in response to positive edge of binector
U621 SYNT or a table overflow (return jump to start of table), the
jump is initiated by the user or the end of the table.
