A lightning strike took our the Minas A4 MDDDt3530 and MDMA 1kw motor in our anchor winch. I found replacements with MDDDT3530003 and another 1kw MDMA motor. Once installed the motor jogs just fine, but when I trigger the remote on/off switch it hums slightly and turns very very slow - +/- 1-2 rpm.Almost as if the brake is not releasing. How can I release the brake? I have been in the manual until my eyes are crossed with no luck. Perhaps it makes sense to someone, but not a simple sailor like me. Any help will be most sincerely appreciated.

A Minas/Panasonic servo motor that has a brake requires 24vdc across the two wires that go to the brake. Check your 24v supply

[CNCMAN172]

The drivers on these units have many parameters. When you swap the driver the parameters must match what the original driver had set. If the old driver was still good u could try the new motor with old driver. Other option is to power up old driver and step down the entire list of parameters and write them down. Then switch to new driver and program each parameter. They can be programmed via the driver front panel interface or using Panasonics Panaterm software

[HVVega]

The old driver was fried so does not even power up. That would have been my first resort. I went through the new driver (used) and reset all to defaults. The motor jogs a treat but when I use the remote on/off switch motor hums lightly ,but turns extremely slow. I really would appreciate some help with the proper settings.

[HVVega]

Ours uses a 12VDC control voltage. Same as the old system. According to the specs that should not be a problem.

In order to help, you need to provide more information. You said this is an anchor winch, for like a boat? You need to describe how the remote on/off switch is connected to the driver, which pins? Perhaps a few pictures, there are many parameters that dictate who the inputs on the driver are used. Documentation for this driver is readily available online. The parameters will tell the motor/driver pair how to react when an input in triggered. I have a great deal of experience with Panasonic drivers, but without more detail it is hard to guide you.

Thanks for the help. It is really appreciated. I do not even pretend to be an automation engineer, but needs must. Yes. It is the anchor winch for historic vessel Vega. (vega1892.com) Have a look at our website. System consists of MDDDT3530003 and 1kw MDMA motor. Original was MDDDT3530 and 1KW MDMA motor. As advised I installed a 12VDC to 24VDC converter to supply 24 VDC to the control line. That made no difference. Original system used 12 VDC. Cables for CNX2 and CNX6 are factory new with connectors. The external on/off control is a simple heavy duty rotary switch connected via Connector, CN X5, as is the 24VDC input. This is the same cabling we used before. I checked both voltage and switch function and both are good. When I jog the motor it runs a treat. When I use the on/off switch, the motor hums slightly and speed vacillates rapidly between 0 and -1. I returned all settings to defaults according the manual. Only change is pr02 set to 5. I tried pr02 at 1 and 2 but no difference.

[CNCMAN172]

Please be very careful changing parameters if you do not know what you are doing. You can burn up a brand-new motor and driver in a few seconds if you set a parameter wrong. I will download the manual and examine the inputs to the CN X5 connector. How did this winch work with the switch when it worked correctly? When you rotated the switch to on it pulled up the anchor? Please describe how things worked before the motor/driver went bad. Thanks

Here is a diagram of the X5 connector interface. I need to know which pins are used in your application on that connector. This will help me determine which parameters needs to be set correctly.

It would not let me paste in a photo, so look on page 25 of this PDF file.

Just watched your video and I saw the anchor winch. So the woman rotated the switch and the winch started turning. Are there three positions up , down, off. .??

[HVVega]

Morning. Thanks again for your kind assistance. There is only one position. Pulling up. The switch has only on/off. Will open the connector today and try counting pins. Shame we cannot post images here.

[RaderSidetrack]

It is possible to post images to this forum. Try using the "Go Advanced" button in the Edit Window to see the Manage Attachments button. However, there are limits to the permissible image size. If this is an issue, one option is to shrink the images before uploading.

Another option is to post images to a 'photo host' and then post a link here. Photo hosts are sites like Flickr, Imgur and Postimages.org etc. My suggestion is to get a free account at https://postimages.org/ which will accept images of any size, then post a link to the image(s) here.

I tried my best to make this clear. Hope I got it right. Imagine the connector in place and seen from behind. I gave the top right PIN the number 1.

Pins 2 & 3 are the switch V- output. (Ground when switch closes)
Pins 4 & 9 are DC negative, including DC supply negative

4th down from top left is DC + input.

I hope that helps.

Send me some photos to [email protected] and I will do my best to see if we can get you working again.

You said the switch only turns on the winch, so that pulls up the anchor. When you drop the anchor is there just a brake you release so the chain and go down into the water?

[HVVega]

I will send images shortly. You are correct. the winch only hauls up the anchor. To drop it we release a mechanical brake on the winch itself that allows the capstan to free wheel.

Thank you for the picture of the connector. I will send you an image of a connector with numbers as you cannot tell exactly which pins some of the wires are attached. Please make sure the control is connected to 12V for the control voltage. This driver and use 12 to 24V for control, however I am almost certain they have the motor driver configured for analog input for speed which is normally 0 to 10V and they are using 12V is my guess. More shortly.

Hi,
I've had no experience with Panasonic servos, but have had plenty with Delta servos. Most modern servos are very similar....if one manufacturer adds a feature then all the others jump on the
bandwagon too. They all have different terminology but by in large if you can program one from manufacturer A then you can also program one from manufacturer B.

I would guess CNCMAN172 is correct. The servo is programmed and used in velocity mode with the motor velocity determined by an analogue voltage 0V to 10V. That is how I would program a Delta servo too.

Within the Delta programming there are a number of parameters that determine how the servo responds to that analogue input. For instance you can change the gain so that it operates over 0V to 5V, or add a bias,
and more particularly you can set the motor speed at the max input voltage. It may be that your original servo was programmed to run at 2000rpm when full (10V or maybe 12V) analogue voltage is applied,
but you new servo is programmed to do only 200rpm with the same input. Were you to change that parameter to match the original, the new servo would perform like the original.

You might claim that you are a sailor and know nothing about these matters......tough s****t, if you want to get it to work then you'll have to put your thinking cap on and learn what is required. After all you did learn how to sail
and as a fellow sailor there is plenty to learn and much of it is very subtle indeed. Programming a servo should be a much easier task even if unfamiliar.

Craig he sent me photo of how it was wired and I sent him the parameters to implement speed select using and outside switch. It does not use an analog voltage input never seen this exact configuration.

[joeavaerage]

Hi,

bugger!

I wonder if the servo has been set-up as a series of waypoints. I've seen plenty written about them but have never had need of that style of control. Would make it damned
hard to replicate.

WOW! Huge thanks for the help. I used the pr settings you suggested and they worked perfectly. Thanks again for sharing your experience and time to help us.
