2.1 Setting Parameters According to Machine
Characteristics
This section describes how to set parameters according to the dimensions and
performance of the machine to be used.
2.1.1 Changing Motor Rotation Direction
The Servopack provides a reverse rotation mode in which the direction of Servomotor rota-
tion can be reversed without altering the Servomotor wiring. With the standard setting,
forward rotation is defined as counterclockwise (ccw) rotation viewed from the drive end.
If reverse rotation mode is used, only the direction of motor rotation will be reversed. The
direction (+/−) of axial motion is reversed, but other items remain unchanged.
