Epsilon Eb Digital Servo Drive Installation Manual
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 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.
