The three parameters such as setup length, actual length and number of
pulses per meter are mainly used for fixed-length control.
The length is calculated through the pulse signal input via the input terminal
DI, and it needs to set the corresponding input terminal to length counting
input terminal. It generally needs to use DI5 terminal input when the pulse
frequency is relatively higher.
Actual length (F7-06) is used for storing the length value calculated. Before
calculating the length, it can modify this parameter value as the initial value of
length calculation, and the actual length is added on the basis of this initial
value, and the actual length calculated will be stored upon power-off.
Actual length =initial value of length calculation plus number of length
counting input pulses/number of pulses per meter.
When the actual length (F-06) exceeds the setup length (F7-05), it outputs
“Length Arrival” signal via the digital output terminal “DO terminal”.
It can perform length reset operation by setting the external input terminal to
“Length Counting Reset” function.
Caution: The current length counting value can be timely viewed via the stop
or running display parameter. Refer to F7-13 and F7-14 function codes for
details.
