inclusively in this manual as the NI SMD-761x.
This manual is not applicable for NI SMD-7610/7611/7612 devices. Refer to
Note
to the unique documentation for information related to the NI SMD-7610/7611/7612.
Functionality on these devices are roughly equivalent. The NI SMD-7613/7615 operates from
18 to 53 VDC, and has a running current of up to 5 A per phase. The SMD-7614/7616 operates
from 18 to 88 VDC, and runs current up to 10 A per phase. The SMD-7615/7616 features
encoder feedback.

Page 46: Drive Heating
Speed (RPS) Drive Heating While NI SMD-7613/7614/7615/7616 devices efficiently transmit power between the power supply and motor, they do generate some heat in the process. This will cause the temperature of the drive to rise above the surrounding air temperature and may also require that the drive be mounted to a heat conducting metal surface. - Page 47 = 1.0 °C/W θ Narrow side of drive mounted on a non-heat conducting surface: R = 2.1 °C/W θ Figure 70.
