information for panasonic servo drives

Hi guys,

I am currently retrofitting my Sodick CNC machines with a PPMC controller from Pico Systems. I am having a problem finding information on my particular drive/motors. The model numbers are:

drive: MDD 203 K1T
motor: MDM 152K1C, MDM 202K1C,

as close as I can find:

MDD - middle inertia
20 - 2 kW
3 - three phase

The remaining letters don't match anything. Information about the encoder is missing. Any help is much appreciated. Thanks.

I am guessing that the problem is that you don't have the cables? Otherwise it ought to just be a case of wiring them together and applying the control voltage to the drives.

A direct email to Panasonic might help.

I'm trying to contact my Panasonic friend that I get my servos and drives from now to get some info.

I wonder if the RX RX/ are feed back to the drives like a tacho velocity feedback. (from the IRC this morning)

The machine I am retrofitting came with encoder cables, connected from the encoder directly to the controller. The Panasonic manual I have found to best describe my drive/motors show that the encoder should connect to the drive.

To add to the confusion, the included encoder cable is comprised of the correct plugs, a 25 pin dsub on the controller side, that the manual says should connect to the drive. But, the pinouts described in the manual are very different than what I am observing.

For others, John is referencing the encoder diagram I am working off of:

I will try to contact Panasonic as well. Thanks for the help.

My Panasonic guy can not find anything on those part numbers.

Hi,

Thanks for the effort. I also tried to get some information from Panasonic, and from Sodick, the machine manufacturer, without luck. I have made a chart of pinouts, taken from the machine electrical diagrams, and have matched it with some information regarding the current controller.

The chart is available at my dropbox: dl.dropbox.com/u/8975057/CURRENTCONTROL.xls

The controller is able to output both PWM and analogue signals. I am currently testing signals on a working machine to find out what connections are being used.

Hi,
How is the project going?
Have you succeed in making it run?
I just purchased a pair of that model (Sodick-450MC)
Hope you can give me some guide on it.
