The speed of the frequency conversion motor M1 is fed by the 4 ~ 20mA current signal fed back by the load cell carried by the electronic belt scale through the A / D and D / A modules in the HLC.
The speed size of the variable frequency speed motor M1 is transmitted to the feedback signal via the A/D and D/A modules in the HLC by the 4 to 20mA current signal from the load cell with the electronic belt scale
The rotation speed of the variable frequency motor M1 is fed back by the weighing sensor of the electronic belt scale with 4 ~ 20mA current signal, which is transmitted to the<br>
