FP0R
To perform the control with the maximum target value, positive integer numbers must be specified for all the
target position data.
[When the maximum value control is performed]
Using the maximum target value of data table or hardware/software reset signal enables the value to return to
the starting address of data table. (V1.06 or later)
In add operation, the elapsed value will be cleared to 0 when it reaches the maximum target value (when reset
signal is detected), and the starting bit of position notification relay will be turned on.
In subtraction operation, when the elapsed value reaches −1, the maximum target value will be set as the
elapsed value, and the bit corresponding to the target position "m" will be turned on for position output.
Note: Hardware reset is CH0: X2, CH1: X2, CH2: X5, CH3: X5.
Description of hardware reset signal operation
When the maximum value control is
not performed
The elapsed value is cleared to 0, and the
V1.06 or later
table pointer moves to the beginning.
V1.05 or older Only the elapsed value is cleared to 0.
When the maximum value control has been specified, set the maximum target value to a large value which
cannot be reached for returning the value to the starting address of data tabe using the hardware reset signal.
Sample operation: When controlling the high−speed counter CH0 with the maximum target value
Example: If the instruction is executed on the leading edge of the trigger R3, and the elapsed value when the
execution is started is smaller than the target position 1
The target position notification area is specified from R10.
