10.4 High-speed Counter Cam Control Instruction
10-19
 Upper limit control
With the F165 (CAM0) instruction, the control with a specified upper limit can be performed.
The settings for enabling/disabling the upper limit control and the upper limit are specified in
the data table.
Upper limit control: Enable Upper limit control: Disable

range
When
added
When the elapsed value exceeds the
upper limit, it returns to 0.
When the elapsed value exceeds the
positive maximum value, it returns to
the negative minimum value.
When
subtracted
When the elapsed value falls below 0,
it returns to the upper limit.
When the elapsed value falls below
the negative minimum value, it returns
to the positive maximum value.

(Note 1): When specifying the output relay (Y), values are also output to the CPU output as well as operation
memories.
(Note 2): When the number of target values [S+6, S+7] is set to 1-16, the cam output is allocated to one word of
output device. When set to 17-32, it is allocated to two words of output device. Refer to the next page for
details.
(Note 3): The number of target values specified after [S+8, S+9] varies according to the number of target values
specified in [S+6, S+7].
(Note 4): The upper limit of the data table end is valid only when the upper limit control is set to "Yes" in [S, S+1]. This
setting can be omitted when the upper limit control is set to "No".
(Note 5): The data table varies in the range of 12 to 138 words according to the number of target values and the
specified upper limit setting.
