The above function code is used for fixed length control.
The length information is collected by the multi-function input terminal, and the number of
pulses sampled by the terminal is divided by the number of pulses per meter PB-07, and
the actual length PB-06 can be calculated. When the actual length is greater than the set
length PB-05, the output length reaches the ON signal.
During the fixed length control, the length reset operation can be performed through the
input terminal (28).
In the application, the corresponding input terminal function needs to be set to “length
count input” (27). When the pulse frequency is high, the X6 port must be used.

The count value needs to be collected through the multi-function digital input terminal. In
the application, the corresponding input terminal function needs to be set to “counter input”
(function 25). When the pulse frequency is high, the X6 port must be used.
When the count value reaches the set count value PB-08, the multi-function digital
output "sets the count value reached" ON signal, and then the counter stops counting.
When the count value reaches the specified count value PB-09, the multi-function digital
output "specified count value reaches" ON signal, at which time the counter continues to
count until the "set count value" is stopped.
The specified count value PB-09 should not be greater than the set count value PB-08.
Figure 6-29 is a schematic diagram of setting the arrival of the count value and the arrival of
the specified count value.

Multi-segment instruction and simple PLC function
The multi-stage command of the inverter has more functions than the normal multi-speed. In
addition to the multi-speed function, it can also be used as a voltage source for VF
separation and a given source for the process PID. To this end, the dimensions of the
multi-segment instructions are relative values.
