5 About this product
5.1 Product description
The purpose of the MM7.10 inertial sensor is to measure the physical effects of
the yaw rate, rate of roll, and of transverse, longitudinal and vertical acceleration.
When mounted appropriately (i.e. according to the offer drawing), the MM7.10
measures the yaw and roll rates as well as the lateral, longitudinal and vertical
acceleration of the vehicle.
In order to prevent signal interference or negative power supply impacts
on the MM7.10, we recommend the supply of the MM7.10 via the control unit or
terminal 15 with separate ground connection.
Due to the sensor's sensitivity to acceleration across the entire frequency range,
it is necessary to test the MM7.10 during the application approval process.
Please also observe the data shown in the offer drawing.
The MM7.10 in combination with the software library ASlib-IMU and acontrol unit–
can realize an angle output in Euler format. The ASlib-IMU must be integrated into the
control unit. The sensor signals are read in via the control unit, offset to angle values
by the software library and made available on the CAN bus.
The ASlib-IMU can be found on the BoschRexroth website in the area MyRexroth
under ME Partner Download Space.
