Power Dissipation
In general, the drive power stages are 90 to 95 percent efficient depending on the actual point
of the torque speed curve the drive is operating. Logic power losses on the EN drive is 11 W
minimum to 21 W depending on external loading such as FM modules and input voltages.
Logic power losses on the Epsilon drive are 11 W with normal loads to 15 W with additional
loads such as external encoder and low input voltage (<22 VDC on A.P.S. or 120 VAC on
AC input).
The values shown in the table below represent the typical dissipation that could occur with
the drive/motor combination specified at maximum output power.
