Accelerometers

2 x 3G accelerometers
The EP3752-0000 EtherCAT Box has two 3-axis accelerometers. These are attached to the underside of the
PCB, each offset by 90°.
Fig. 6: Location of the accelerometers
The image shows a top view and a side view of the EtherCAT Box. The position of the accelerometers is
shown inside the box:
• Green indicates the position of the PCB.
• The accelerometers are numbered 1 and 2. They are mounted on the underside of the PCB.
Due to the position of the sensors on the underside, an acceleration (e.g. the earth's gravitational force) on a
flat, even surface (e.g. when testing on the laboratory bench) is displayed as a negative value.
