Difference Between OMRON V1000 To YASKAWA V1000

I suspect that they are the same drive. However, the default settings in the new Yaskawa drive may be different than the old Omron drive.

What you will need to do here is go through the literally hundreds of settings on the new drive and make sure they match with the settings on the old drive.

The good thing about this is that the same procedure to get into, navigate, and change the settings on the new drive is the same as the old.

The bad thing is that, if you don't have a record of the old drive's parameters, electronic or at least hard-copy, you will have to power it up to get them, or, if the old drive is toast, you are going to have to play around with the new drive's settings until you get it right.

I have been right where you are!

I agree with Mikerho that both drives should be the same one. I remember working with an OMRON V1000 on my previous company and I recall that it was actually YASKAWA or viceversa, so they should be the same one.

It seems to be more likely a problem with the configuration. There is a parameter on it that changes the functions of the six drive inputs, depending on it they will result in different actions on the drive behaviour. For that reason you must ensure that you always verify your inputs configuration with the documentation you have got on the inputs functions (schemes, manuals...).

Somehow, a signal related to the photo sensor status should be coming up to one of the drive inputs, and this one has the stop function asignned (or the second speed function if this is defined to 0 Hz). The multi stop issue does not make any sense for me, probably those inputs are related to first and second speeds (which should be defined on the configuration), which will make sense with the multi step naming.

Right now I have no access to my notes and documentation on V1000 drive, but I will through the weekend. I will try to take a look on those and let you know if finding anything.

Hope this will help you. Regards.

Hey Santim! GA (Good Answer)! Hopefully someone will support my vote with another (to make it a REAL good answer). It's good to get a GA on your very first post!

Welcome to CR4!

Thank you Mikerho! I've been taking several looks to diverse threads on the forum, and when I saw this one, that I have been recently familiarized with, decided to break the ice and get into the discussion.

It's always satisfying to get recognition!

YASKAWA actually makes the Omron drive as well as other names. There is no functional difference. The age of the drive would be the only difference, Firmware evolves as any drive is in production.

All right, I've found some time to review my notes and documentation and find the configuration parameters which govern the digital inputs functions.

In this link you can find the manual to which I will refer, just choose the downloads tab and the user's manual document:

http://industrial.omron.eu/en/products/catalogue/motion_and_drives/frequency_inverters/general_purpose/v1000/default.html

On page 160 you will find that the values on parameters H1-01 to H1-06 determine the digital inputs behaviour. The most common ones are run/stop, multi-step speed references (those are the main reason to use a frequency inverter), up/down and baseblock. You will find descriptions for them on the following pages.

Of course, I also recommend you to perform an auto-tunning, so you can rule out that it is a failure with the motor configuration.

Have you been able to find a reason for the drive stopping when the photo sensor activates? Hope this will help you to fix the problem, otherwise, let us know, several heads will come up with more ideas.
