Hello, I recently asked for some advice on reasonable priced Servos. Thanks for you suggestions.
I think I'll go whit motors from Nanotec, the DB42C01 one for example: http://de.nanotec.com/produkte/633-db42/ http://de.nanotec.com/fileadmin/files/Datenblaetter/BLDC/DB42/DB42C01.pdf I'd get the suitable encoder NOE2-05-K14 (this is the 5V type, there is also a 24V version available): http://de.nanotec.com/produkte/produktkonfigurator/ I'd also like to have some breaks, but I'm not sure if I go for the Nanotec solution: http://de.nanotec.com/produkte/387-bl-bremse/ The drive system is supposed to pull a synchronous belt to create a linear movement. I think so fare I'm good to go, but I'm unsure about the motor controller. I'd like to control the drives using LinuxCNC (of course) and a Mesa I/O card. While I more ore less familiar with LinuxCNC I've never worked with one of the Mesa cards nor did I ever user servos and encoders. But I'd like to change this for this project. In total I need 4 maybe five simultaneous axis. Three of which move an end-effector, the forth is part of the end-effector and has to be controlled via WLAN, Bluetooth, etc. The mentioned motor is a 50W 48V BLDC motor. There is a Mesa driver that seams to be suitable: 7I39 Dual 250W 3 Phase BLDC driver http://www.mesanet.com/motioncardinfo.html http://www.mesanet.com/pdf/motion/7i39man.pdf The price is OK, and I guess it would play nicely with the 5I20, but I'm thinking about getting one with a larger FPGA, for other experiments later, like the 5I22-1 or 5I22-1.5. Shod work just the same, right? Now some questions: How much effort does it take to setup a system made from the mentions component. I other words, how much of the necessary configuration work is documented in ready to use examples. I'm usual not at all afraid to dive into something new, but in this particular case everything has to be up and running in four weeks. The distance between the servos and the PC controlling them is quite long, like 10 to 20 meters. Where should I place the motor controller, next to the motor or next to the PC and the I/O card? Would would be easy way to gain control over the froth servo via some kind of wireless link? My idea so far is to place a Raspberry Pi Board next to it and use a smart controller like the Mesa 3C20, hook it up to the embedded Linux board via RS485 and write a mini program to receive commands vie WLAN and send them to the controller vie RS485 and vice verse. But how could I get LinuxCNC to send and receive the proper commands via LAN (UDP, TCP or what ever might be handy). A communication lag and the resulting asynchronous movement is not an issue. Using the Geckodrive G320X Digital Servo Drive might be easier, but I'm not sure. Any completely different ideas? Sorry for the long message, but I hope you can give me some advice.
