Thread: IMO JAGUAR VFD help needed
Checked for voltage ...Stable 0.65 volts no change when trying to accelarate
Now I understand what you mean Birchy.
But at the moment I am not getting any voltage measurements at the machine speed control output
Maybe there is some fault there.
Yes, if it is a constant 0.65V throughout the selected speed range, then something is wrong. If that's the case, then maybe your original Parajust drive is OK but your CNC control is faulty?

This is quite probable? Is there anybody else here that can check against theirs?If the nagging gets really bad......Get a bigger shed:naughty:
Thank you both.
I am reading the Parker manual and it says ...\for Fast rotation requires pin 20 of 32 Pin input socket of SD2 drive to be connected to 0volts.
So I am now measuring the keyboard lines which leave the arrow button for manual jog, as the drive connecting socket not accessible, and is reading 4.8vdc.
When pressing the arrow button the test point voltage comes down to 0.650V
And when I keep this button pressed the screen shows the axis coordinates changing.
I must be totally blind I can't see what is going on. I must be real close solving this. Please note that I used a jumper wire to bridge the limit switch computer input to save some time testing limit switches. IF I do not do this the motors de-energize. Should i have done this or not?
