The UDMCB is a line of economical and compact PCB mounted EtherCAT drive modules.

The UDMCB is specifically designed to complement the highest performance NPMPC  drives and address the needs
for a more economical drives. It has the same form factor as the NPMPC and same connectivity.
One customized carrier board can be used for both modules.
Such a carrier board design enables customization of connectors, I/O configuration, STO and other safety related functions.
For prototype testing and carrier board design reference it is recommended to use the UDMPA.
The UDMCB is a slave that runs under any ACS EtherCAT® masters.
A comprehensive set of software support tools are provided for configuration, setup and tuning.
