Hello I own a spa repair buisness and I am attempting to fix a water treadmill system at a non profit animal rehabilitation center. Its a little out of my scope but it thought I would try and help them out.

The old drive had burnt out and no longer lit up at all.

I replaced Drive 6SL3210-5BB21-5UV0

With Drive 6SL3210-5BB21-5UV1

The new drive has been commissioned by siemens tech support over the phone and is receiving good telegrams but when control buttons (forward,reverse) are blessed on the HMI nothing happens.

I have installed TIA Portal V13 as that is the version that the PLC was programed with. I can see the plc after creating a new project and searching for devices under my USB to ethernet adapter.

what do I do next? How do I make the plc control the new drive with the hmi? 

Any help would be greatly apretiated. These dogs need the water treadmill to heal from their injuries.

Thankyou for the prompt reply!

The plc was burnt out completely. Nothing on the screen at all.

I can move the treadmill manually from the new drive but it does not respond to commands from the HMI.

The PLC is connected to the drive by only 2 wires. (Red P+) (black N-) at the drive and (black TA) (red T/RB)

The other devices controlled by the plc are the jet pump, recirc pump and the heater.

I am not 100% sure what you mean by web pages or panel buttons but I used the buttons on the v20 drive to commision it.

Do you happen to know what I have to change in the plc programing to make it control the drive from the hmi like it did with the old one?

Thankyou for your time.

 I haven't had a chance to look at the specific units you posted but that is MODBUS (or USS) wiring. If there are no other wires from the PLC to the drive then it will be a communication settings issue.

If the old drive is cooked then you will need to look at the program in the PLC to figure out which protocol they're using and what the parameters are, specifically device address. 

Upload the program for someone to have a look for you.

Out of curiosity, what kind of HMI you referred to?

 That would be great if someone could look at this project. I think I uploaded the plc into the project properly.

In the V20 manual, it will describe ways to configure the drive to communicate with a PLC using the communications cable.  I provided a link to the manual in my earlier reply.

I do not know about V20's, but in general I think Siemens drives need an address, and whatever address is in the PLC programming needs to match what is in the drive.  If you change the address, it might work without further changes.

When you are done, be sure to find the command to save running configuration to permanent memory (what Siemens traditionally referred to as saving RAM to ROM).  This way, after power off condition, the drive does not require reconfiguring after power up.  I imagine Siemens support already gave you assistance on how to do that.

This is the new drive unit that won't respond to the Forward/Reverce commands from the HMI. The resistors were not installed on the old unit but Siemens tech support asked me to install them anyway as he said technically they are required.

 Hello John. May this message find you well.

EDIT ..
I am missing mention of the normal input and output wiring that exists between PLC and drive. It is not impossible that a hard-line enables the drive and that this wire has a problem.

Attached are snapshots and extracts of the program and manual. See if it helps and if I missed something experts on the forum or siemens support should be able to pick it out.

Edit: I updated the attachment to include setting for telegram time off.

The company I am doing the work for had a falling out with the builder of the system. The builder is claiming that the perimeter values are proprietary so they will not disclose them. They offered to sell them a new drive for over $1k with the parameters set the way they should be.

This is 3 months after the warranty on the $60k animal water treadmill system expired and the new drive lists at like $300 (without the parameters keyed in ahead of time).

Unfortunately I can not get the parameters off the old drive as it is toast.

I guess I will give Siemens extended support a try and see what they can do.

Thankyou for taking the time to put all that together for me. One question though. The image you sent has PZD_LEN as 4 and in the manual you highlighted it as 2. Which should I use?

 Use 4 and it actually doesn't matter, I believe, as it is rewritten by the instruction anyway.

Have you done the basic troubleshooting by looking at the logic and making sure the inputs that need to be on are on and those need to be off are off etc ?

I recall an E-Stop in there somewhere.

What did siemens do for commisioning, did the setup the communication or just the motor?

There's one more parameter that if was changed from default could be an issue. It is a parameter setting for DI1 (digital input 1) which needs to be turned off (0) otherwise it would have to be wired as it would the function as enable input; it's P0701

What are you seeing on the drive? Post lots of picture if the drive, plc wiring and LEDs and anything else you can think of.

If you purchased the replacement drive through a local authorized Siemens distributor, contact them and see if they have a drives specialist on staff or maybe available in the region.  Maybe they can help you over the phone resolve these last important details.

 When I follow the directions you highlighted and set PZD_LEN to 4 the treadmill now responds to forward and stop commands from the HMI.

The only issue left is that the drive is not sending any info back to the plc so the plc does not know the drive has started moving so I can not adjust the set speed of the treadmill and the reverse button also makes the treadmill belt go forward instead of backward.

The hmi does not display a current speed or render the button green when activated.

Any ideas? Looks like we are getting close.

Look in P0922. It may be 1, or 2 or something else.  It's the telegram # used by the drive.

Then post the values in p2090 .. p2091 .. p2092 .. p2093

The attachment shows how part of the logic works and it is based on a drive set for a max frequency of 114.80 Hz.

I can not recommend making any changes to the drive parameters, commissioning the drive for the motor connected to it and the application is your responsibility.

Reboot the entire system by turning the power off and wait a couple of minutes then turn it back on.

There are two inputs that must be ON, The E-STOP I0.0 and Exercise Machine Switch I1.0

Do not press any buttons or make change settings on the HMI other than the buttons you showed in the images you uploaded, specifically there may be a button "Change speed" on some screen somewhere, do not press it.

Press STOP button on HMI, just to be sure.

Then press forward or reverse button and then start increasing the speed; that should work just like that, if it doesn't then you will need to provide much much more information:

- Image of motor plate

-Communication parameters set in drive.

-Motor parameters set in drive.
