„ Rotation Direction Selection
The SVA Module provides a rotation direction selection that can be used to reverse the direction of
rotation of the servomotor without changing the motor wiring at the SERVOPACK. The rotation
direction selection only reverses the direction of rotation of the servomotor. The direction (-, +) of axis
travel will change. Nothing else will changed.
■ Operation Example for Standard Setting
■ Operation Example for Reverse Direction
The following parameters must be set to perform control in reverse mode due to the structure of the
machine or other reason.
• Rotation Direction Selection SERVOPACK Parameter
• SVA-01 Module Fixed Parameter Setting
