Figure 5.5: Power supply requirements for TRINAMIC modules in a bus system
In large systems it may make sense to use an optically decoupled CAN bus for each number
of nodes, e.g. for each base board with a number of TMCM-34x modules, especially when a
centralized power supply is to be used.
Be aware that different ground potentials of the CAN sender (e.g. a PC) and the power supply
may damage the modules.
Please make sure that the GND lines of the CAN sender and the module(s) and power
supplies are connected by a cable.
