This section describes how to set parameters according to the dimensions and performance
of the machine to be used.
3.1.1 Changing the Direction of Motor Rotation
This SERVOPACK provides a reverse rotation mode in which the direction of rotation 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, the direction of motor rotation can be reversed without
other items being changed. The direction (+/−) of axial motion is reversed.
