voltmeter put on the pins showed in the diagram below, you can adjust the output speed set on Mach3.
In order to adjust your voltage, set your control software at maximum speed and then turn the pot until
you reach the desired output voltage. Make sure that when you reach the max speed in your software
you get 10 VDC out. This adjustment is made to calibrate the VFD for maximum speed.
For configuring Mach3 follow these steps:
•
Go to config/ motor tuning/spindle motor movement profile. On steps per unit 1000, for
velocity 1500.
•
Under step pulse length, use a number from 1 to 5 micro second. This number is directly
proportional to the final voltage you will get in the analog output.
•
Use this number and the fine tuning pot to adjust the voltage you want to get max speed.
