All that is needed is a PC, MaxTune or ELMO range of servodrives and PBA direct drive motors. When using CANOpen, you will need a CAN Interface.<\/p>\n<p>With this minimal configuration, it is easy to create a GUI (Graphical User Interface) in Windows.<\/p>\n<p><strong>PBA Systems MaxTune Servodrive<\/strong>\u00a0can simply accept ASCII command from RS-232 and CANOpen.

It even supports synchronization between multiple axes using &#8220;Position, Velocity, Time&#8221; (PVT). However it is not recommend to use PVT since Windows is not real-time and due to the bandwidth limitation of CANOpen.<\/p>\n<p>PBA Systems has implemented many GUIs for its customers.
