3.1.1 Changing the Direction of Motor Rotation
1) 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.
2) 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.
