CNC production and processing technology: according to the workpiece by CNC machine give a speed by converter, the speed signal is a CNC 0-10v analog, converter according to the speed quick response. Again according to the given signal control feed, the blade motor move to complete workpiece machining.
CNC
; The motor name plate
According to motor power use PI9100 004G3 vector inverter. Motor rated speed 1480 r/min, and users need the highest speed 3000 r/min. In order to satisfy the customers' needs, we can set the highest frequency and maximum frequency to 100 hz.
Installation
wiring diagram
Frequency inverter installed in electrical enclosure, PI9100 004G3 has a small size, compact structure, convenient user to install and use, do not take up too much volume.
Frequency converter connection:
1, the main terminal connection:
L1 / L2 / L3 to 380 V input, P + and RB connect braking resistor, U/V/W connect motor .
2, control terminal wiring:
AI1, GND indirect CNC 0-10 v, for speed given,
DI1, COM connect "forward" switch signal, tclosed forward and disconnect stop.
DI2, COM connect "reverse" switch signal, closed reverse, disconnect stop.
