General Function Description
For each desired reaction, a cam can be setup on a track.
The size and position of this cam can be specified by writing the respective initial setpoint A and
the end setpoint E of the cam into a data block (IP 241).
By means of the standard function block FB 156, this data block is then transferred to the 1P 241
and the module is parameterized.
During parameterization, the
1P 241 firmware internally arranges the specified initial and end set-
points into an ascending sequence of values.
This is done to obtain brief processing times when these values are processed (i.e., when the ac-
tual values from the encoder are compared with the setpoints).
Then the actual value only needs to be compared internally with the next highest and next lowest
setpoints and not with all specified values.
must be considered during configuring.
Track Identifier Bits
The result of the comparison with the setpoints (cams) is presented as track identifier bit.
Within the cam, the track identifier bit is “O”, outside the cam it is”1”.
Example:
Actual value
4
D
Total track
Track identifier bit = 1
Track identifier bit = O
