Installation Notes
Correct installation is essential for accurate motion measurement.
The IMU570 follows the right-hand coordinate system for axis orientation.
Axis Definition
X-axis: Forward direction from the connector
Y-axis: Right side direction of the device
Z-axis: Downward direction toward the bottom of the unit
To determine rotation direction, follow the right-hand rule:
Point the thumb along the positive axis direction, and the curl direction of the other fingers represents the positive angular velocity direction.
Proper axis alignment ensures accurate measurement of motion data.
