7.4.1.Normal Batching of Comparison Function
The function outputs the gate control signals that are compared setpoint and weighing data that is accumulated materials to hopper.
When the weight increases above the setpoint, the gate control signal turns off. When the weight decreases under the setpoint, the gate control signal turns on.
There is not direction for the weighing sequence in this function. Therefore, the comparison is repeatable (reversible).
Concerning Parameters of the Function
Using the normal batching of comparison function
[5qf- 1] [1] Costomer programmed control [5qf- 3] [0] Normal batch weighing
[Function] - [Function setting] - [Sequence] - [Basic]
Changing waiting time of judgment
[Function] - [Function setting] - [Sequence] - [Timer]
Changing the pulse width of batch finish output
The arbitrary width can be set.
If zero is set, the output keeps until next start. [Function] - [Function setting] - [Sequence] - [Timer]
Using signals of "over", "acceptable" and "under" in the comparison function.
[5qf- 5] Comparison
[Function] - [Function setting] - [Sequence] - [Basic]
Changing the accuracy of the comparison
The average time of batch finish output is set. The output of batch finish delays by the average time.
[Function] - [Function setting] - [Sequence] - [Timer]
Using the manual compensation
[1n
nn: terminal number of the I/O.
The input to control free fall by the external PLC. [Function] - [Function setting] - [Control I/O] - [Input]
