At an active interpolation is interpolated between the table index 29 and 30. It
can be interpolated in 256 steps between these points. The interpolation point
is defined as follows:
n
The input parameters are an integer data type
The lost information (due to shift operation) is used for interpolation with integer data
types.
After subtraction of base value, the index is 0x750B39.
The value of the 7 lost bits (due to shift operation) is 57.
The interpolation point is calculated as follows:
Interpolation must be operated in 256 intermediate steps. If the shift factor
is to be greater than 8, the highest 8 bits of the interpolation com-
ponent would be taken into account for interpolation.
4.6.5.5 State machine of the cam generator
"init" state
The cam generator is in "init" state, if bit 0 = 0 and bit 1 = 0 in
State.
If the cam generator is in "init" state, changes can be made at the parameter settings.
It is checked, if a valid cam was loaded and if an output parameter was selected, during
the transmission from "init" to "active". If the parameter-controlled processing mode is
configured, the cam checks, if an input parameter was configured. It also checks, if the
count of the supporting points complies with power 2 during a cyclical processing within
this operating mode. If the cyclical offset is generated from the cam data, then this is ex-
ecuted during the transmission from "init" to "active". It also checks, if the reference pa-
rameter was selected at the preselected relative mode.
"active" state
The cam generator is in "active" state, if bit 0 = 0 and bit 1 = 0 in
State.
