150 Functions and outputs
HBM QuantumX
You need to connect all modules via FireWire (or use a backplane) for the MX878 to become
operational! You can configure several channels to ”isochronous FireWire transfer” using
QuantumX Assistant software or catman
AP 3.1 or higher.
Please note:
Providing the data via isochronous transfer may use up significant computing power on the
module (in particular on the MX410 module and the MX460 high−speed module). Do not
activate the isochronous transfer needlessly!
Add & Multiply function
The MX878 currently provides this type of computation:
Result = a0 + a1* Input1 + a2 * Input2 + a3 * Input1 * Input2
Where Input1 and Input2 denote the two input channels used for this computation. These
channels will reside on other modules and must have their isochronous FireWire transfer
enabled!
Keep in mind the following notes when working with math channels:
S The maximum sample rate is restricted to 2400 Hz
S The sample rate of the channel must not be higher than the sample rate of the input
channels
S Filters do not apply to math channels. These channels are always unfiltered.
Matrix computation function
The MX878 enables 4 parallel matrix computations each with a maximum of 6 input and
output quantities and 36 constants to be performed.
Generic formula:
Fx = a1*Ufx + a2*Ufy + a3*Ufz + a4*Umx + a5*Umy + a6*Umz
etc. for Fy, Fz, Mx, My, Mz
The ”Matrix computation” function allows mathematical compensation of interdependencies
(crosstalk) of multi−component transducers for force and torque measurement.
The maximum data rate of the input and output quantities is 1200 Hz (< 1 ms computation
time). The computed output signals can be scaled and output as filtered analog voltages by
the same module. The computed signals can also be distributed (isochronously) to the
FireWire bus in real time and output via CAN bus or EtherCAT (MX471: CAN bus. MX878:
EtherCAT bus).
Scaling of the input and output quantities must always be ensured.
An EXCEL compensation matrix can be copied directly to the matrix parameterization (Ctrl +
C, Ctrl + V).
