And that's me just about out of guesses

Stuart

Hello Stuart,
JP4 is at default setting and so is the jog.
I can increase/decrease the speed from the panel and am stuffed why it will not work from the pot.
Thanks for all the guesses.
I will restore all the defaults P.050 and start again.

Can you draw a rough circuit of what you have done?
On my vsd once you set the speed control to remote the local one wont work. So I assume we are missing something.

Good luck

I do not have a P.054 in remote or local. The parameters skip from P.051 to P.060.
Must read the manual and find out why.

Col

Nevermind, I missed this the first time.
"Regardless of the status of P.054, the following conditions must be met in order for the drive to start.
` The terminal strip function loss input must be closed."

Although it is interesting you dont have P.054.

Stuart,
The GV3000 drive plate shows V6.04 but when I checked P.098 it shows V4.42.
I downloaded Manual D23323 from Reliance and the parameters for V4.42 do not include
P.052 to P.060.

Brrrrrr it is too cold to go out there to start again
Thanks
Col

Why do they have to have two manuals!! one for options one for wiring


When you said you could control the speed from the vsd, was this with P.000=rE?

What is the remote LED doing?

Have you tried the Auto/Manual button at all?


Think of the warm feeling you will have when you get it to work lol

Hello Stuart
I started from scratch, reset to defaults and then the motor settings. Bought a new pot and rewired all switches....Still the same as I cannot control the speed from the pot.

In the P.000=rE the run,fwd/rev, jog, start and stop all function.

The remote LED is on and the Auto cannot be activated in the remote mode.

No warm and fuzzy just cold and cranky

Col

Sorry one of my qestions wasn't very clear. When you are running the vsd with P.000=rE, can you adjust the speed with the buttons on the VSD?

Stuart

No. The speed remains constant whether I go up or down with the panel buttons.

Maybe its time to check JP4? http://www.reliance.com/pdf/drives/i...als/D23360.pdf
page 2-15 (or page 25)
Did you get a 5k pot this time?
Is U.0000=0? (it should be, thats the default)

Stuart

Hello Stuart,
We now have power.
Jumpers J4 and J17 are as shown on page 24.
I cannot access the U parameters and have not set any..just used defaults..
Are they for Vector regulation and I have set up Volts/Hertz regulation?
