Spindle Control Output Port - Digital Dream EC500 User Manual

5.3 Spindle Control Output Port

As Picture 5-1 showed,No.3 terminal block is for Spindle control output. We define the interface from
left are COM-,VSO,COM-,OUT1,OUT2,OUT3,OUT4,OUT5. They are Ground of output, Speed adjusting
voltage, Ground of output, Digital output1, Digital output2, Digital output3, Digital output4, Digital output5.
Take Nowforeuer inverter as the example. Spindle control output and the inverter connection showed as
Picture 5-6.X1 control spindle Clockwise RUN and STOP, AIN1 modify spindle's speed. if we need to control
spindle anti-clockwise RUN and STOP, we need to connect X2 to OUT2.
VSO connects to Speed adjustment which defined by voltage 0-10V.
The relationship Max. Spindle speed and current spindle speed is as below:
VSO(Output Voltage)=10*current spindle speed(S)/Maximum Spindle Speed(Max.S).
For example if we set the Max Speed is 24000,and we need the current spindle speed is 18000,then
VSO=10*18000/24000=7.5V.
The following picture 5-7 is the setting method of Max. speed in Mach3 software.
