Variable Speed Control; Operation Mode Jumper - CNC4PC C11G User Manual

VARIABLE SPEED CONTROL

This function lets you control your spindle with PWM signal. It converts the PWM signal
into an analog (0-10VDC).
This function can also be used on many DC motor controllers by replacing the
potentiometer that controls the speed.
Requirements:
It requires a power supply external +12VDC@ 30mA for the analog output
WARNING: To keep the output signals optoisolated, these must not have
common ground or connections to current with other circuits you are using.
You will require a voltmeter to fine tune your system.
Wiring:
Before connecting anything, please be sure to read your VFD's manual and make sure
you understand all the safety issues.
Spindle uses Pins 14 for step (PWM at 1000hz) and 16 for Dir.
