HELP WITH BOSCH ANALOG DC SERVOS

the reason to try to learn linux cnc is that i have 2 sets of analog dc and ac servomotors
(3 pcs dc of bosch and 3 pcs ac from drive system) and i woold like to use them
for converting a marble bridge saw to 4 or 5 axis bridge saw cnc
after little search in the forum ithink that a 5i25+7i77 is a good choise

I ALLREADY ORDER THE 5i25+7i77
HERE SOME PHOTOS OF THE MOTOR AND THE DRIVERS
THE SET IS FROM A WOOD ROUTER
THE ONLY USER MANUAL IN THE WEB IS IN GERMAN AND IS NOT HELPING
ANY SUGESTION ?
THANKS

thanks
i m waiting for the MESA5I25 7I77 this week
do you now the right connection for this servos?

Hi. I used similar drives in my Deckel. Im also using a 7i77. The manual in the link explains the connections and from what i see in the photos above the connections to your drives will be the same as in the manual.

hi Henk
i make my first attempt to connect the driver and the motors with no success
do you have also the same motors??
as you can see in the motor there is 3 connections and i don't have a user manual for the motors
because i don't now what to expect
i don't now how to start
what is the steps that i have to follow
i will make all the connection and then i will do the configuration or the other way around
any suggestion ?
thanks

Hi. Give ne a couple of days to dig out some diagrams..... Henk.

HI
The photos you sent doesn't show the model number of the drives, but they seem to be SM.....T drives. These are Bosch AC servo drive modules.

You need to read the manual in the link above. The drive package consists of a VM power supply module, one SM module for each servo motor and a KM module. There is also an optional EB module that can be added.

The VM module is the DC power supply (DC Link) which is connected to the mains 3 phase supply , usually with inrush current resistors and two contactors. This supplies the SM and the KM (Capacitor) modules with approx. 520V DC power. Without the VM and KM modules you don't have a complete drive system. There are connectors on each of these modules for a communication/monitoring cable that connects them all.

Each of the motors should have three power connections, normally marked U,V and W. These are connected to the very top of each SM module. There must also be an Earth wire. The motors are also fitted with a ROD encoder that connects to the bottom of the SM module. This is for the internal PI loop of the drives (I don't think any output is provided from this encoder for external use so you would probably need additional feedback.)

The enable signal is 24V on pins 0V and FG and the analog control voltage must be connected to SW+ and SW-. You need to check in the manual but I think you need to supply 24V to the drive as well.

Hi
thanks for the answer
tonight i will take some some photos from the actual attempt of connection on the bench
Note that i m trying to connect only the one motor for test
regards

Hi Henk
this is the photo of the connections
waiting for your comments
