DDCS V3.1 Users Manual
PIN3(M8),PIN22(M10),PIN2(VSO) and PIN21(M3) is for spindle control output.The spindle
control output terminal offers connections for Start and Stop of the Spindle (M3/M5), Start/Stop
of Cooling (M8/M9) and Start/Stop of Lubrication (M10/M11). These three output terminals are
signals open to ground. The highest electric current can be absorbed is 50mA. The speed
controlling output terminal can output 0-10V. It can adjust the speed of the spindle motor by
sending the voltage between 0 and 10V to the VFD according the the Spindle Speed Setting.
Controlling the speed of a spindle with a VFD (variable frequency drive) only needs the
Start/Stop signal and the 0-10V signal to control the frequency.
The following table 2-6 shows the wiring with Sunfar VFD:
PIN3(M8),PIN22(M10) and PIN21(M3) is also can be used for OUTPUT ports.For example,it
can be used for a Relay output port.For example the Figure 2-10 shows the wiring methods:
