4.1 Selecting a Servo Drive
This section describes how to select a Servomotor, Servopack, and Digital Operator.
4.1.1 Selecting a Servomotor
The selection of a Servomotor matched to the servo system in which it will be used is based
on the Servomotor model. The numbers (1) to (6) in the following diagram correspond to the
numbers in the Servomotor selection flowchart on the following pages.
