4 SERVOPACK Specifications and Dimensional Drawings
4.1.2 SERVOPACK Ratings and Specifications 2
4-4
* 1. Use the SERVOPACK within the ambient temperature range. When enclosed in a control panel, internal tem-
peratures must not exceed the ambient temperature range.
* 2. Speed regulation is defined as follows:
The motor speed may change due to voltage variations or amplifier drift and changes in processing resistance
due to temperature variation. The ratio of speed changes to the rated speed represent speed regulation due to
voltage and temperature variations.
* 3. Forward is clockwise viewed from the non-load side of the servomotor. (Counterclockwise viewed from the
load and shaft end)
