The NDEM3 (NOVA Device Electronic Module, 3 axis) is the 3-axis drive module of the NOVA system. It drives piezo inertial positioners without built-in electronics, such as the MS30, MS38 and MX25/35 stages.
Power (5 V / 42 V) and communication are provided via the NOVA bus. The piezo voltage can be changed in gradations, and both step size and step frequency (velocity) are adjustable up to a maximum speed of approximately 1 mm/s. Absolute and relative step counters are available.
A programmable EEPROM device ID allows several devices of the same type to coexist in the same address space of the NOVA bus, simplifying multi-axis system design.
