Currently, we have a single drive board holding up to 4 Maxon drives
db11 Board
Features
4 Maxon ESCON 50/5 Drives
Repository on github with Altium files https://gitlab.ost.ch/tech/inf/public/db11
Important: keep connections to cb20 reasonably short! Differential line drivers for the encoders are located on the db11. From there single ended lines lead to the cb20.
existing boards
6 x db11 2015 (incl. production in 2017)
Supply
The board is supplied with 5V and 3.3V directly from the cb20, see below. On P6 you have to deliver 24V (square pad = Gnd).
Important: Connect GND of P6 with GND of the cb20.
Motor Connection
A simple DC-Motor (single coil) must be connected on P5(Pin 1 and 2).
