Are you shutting down and re-powering after setting the parameter?

Yes every time .That resets the drive.

That particular Param. might just need the control power cycled.

One more and I'll see ya tomorrow Johnny, sleep tight.
When setting a param on some drives, you need to  exit that parameter and go to the next before that one will stick.
(I got tricked here with Fugi drives before)
When you go back in, do you see/verify that it was set as you wanted ?

Pr 7.16 Encoder is set at 0 ?
Doesn't look like a valid entry for motor info.

Good night,
Russ

Hi Johnny,

found something interesting in the software manual.

5.2 Velocity mode
First, you need to modify the parameter value of control mode in parameter manage window, make the value of
control mode to 1. then in monitor setting, you need to setup Pr4.00=000300,make the motor enable, then you
need to download and save the new value to the driver, then restart the new values of parameter to make them
available.

can you check Pr.4.00


have you worked throu this chapter 5.2 for velocity mode setup ?
have you checked the voltage on VI1 with a voltmeter ?

anything is possible, just try to do it.
if you find some mistakes, in my bad bavarian english,they are yours.

Couple of additional things, try setting pr5.28 to 11 and see if you can monitor the analogue input.
Open the waveform window and set one of the values to analogue and see if you get anything when you start the sampling.

To Thomas
That was the first I did for a month ago and I have read the manual forwards and backwards several times.
And yes I have checked the voltage.

To Hood
I tried 5.28=11 for days ago and I wrote it too. The problem is still that there is no input.
Right now I have to wait on Leadshine support after 27.feb.
I´m pretty sure that the drives are not ok.I will send this link to the chineese support, then they can read it all if they want to.

To Russ
parametersetting is pretty easy to do on the laptop , you can upload and download to and from the drive as you wish.
And you get a message when you have saved the changes.

I bought the Leadshine product because of their ISO 9001 certification , it´s just not certificate you can buy.It should be a security for the customers.
I hope so.

Leadshine seem to be a reputable company and I have heard decent reports about their support so hopefully they will get you sorted, just a shame for you  it is the Chinese New Year :(
