Note: *DT (dead time): The time interval between the switching of the low side and the high side of a full bridge waveform. The best power
efficiency is achieved when using the maximum dead time (i.e. DT=11). This minimizes the power consumed while having no affect on
speed/push force.
8.2 Integration with UTAF Motors
New Scale Technologies works closely with OEM customers to provide assistance in using the UTAF motor with the NSD-2101. Please contact
New Scale for assistance.
8.3 Integration with Other Motors
The NSD-2101 was designed for use with New Scale Technologies’ SQUIGGLE and UTAF motors. Support for other piezo motors may be
provided, for a fee, to qualified OEMs. Contact austriamicrosystems or New Scale Technologies to discuss your application.
