Real Time Math Setup (RealTime Math Setup)
Select an operator or function (operation definition), and then set its corresponding items.
Operators and Functions (Operation)
• S1+S2: Adds the waveforms assigned to Source1 and Source2
• S1−
S2: Subtracts the waveform assigned to Source2 from the waveform assigned to Source1
• S1*S
2: Multiplies the waveforms assigned to Source1 and Source2
• S1/S2: Divides the waveform assigned to Source1 by the waveform assigned to Source2
•
A(S1)+B(S2)+C: Performs addition with coef
ficients on the waveforms assigned to Source1 and Source2
• A(S1)−
B(S2)+C: Performs subtraction with coefficients on the waveforms assigned to Source1 and Source2
•
A(S1)*B(S2)+C: Performs multiplication with coefficients on the waveforms assigned to Source1 and Source2
• A(S1)/B(S2)+C: Performs division with coef
ficients on the waveforms assigned to Source1 and Source2
• Diff(S1): Performs dif
ferentiation on the waveform assigned to Source using a fifth order Lagrange
interpolation formula
•
Integ1(S1): Performs integration on the positive component of the waveform assigned to Source
•
Integ2(S1): Performs integration on the positive and negative components of the waveform assigned to
Source
•
Rotar
y Angle: Uses the waveforms or logic signals that have been assigned to phases A, B, and Z to calculate
the angle of rotation. This can be used to calculate the angle of rotation or the displacement of an encoder.
•
DA: Co
nverts the logic signals that have been assigned to Source1 (the least significant digits) and Source2 (the
most significant digits) into an analog waveform and scales the results
•
Polynomial: Performs a quartic polynomial calculation on the waveform that has been assigned to Source
• RMS: Calculates the RMS value of the waveform that has been assigned to Source
•
Power: Calculates the ef
fective power of the waveforms that have been assigned to Source1 and Source2.
• Power Integ: Integrates the ef
fective power of the waveforms that have been assigned to Source1 and
Source2.
•
Log1: Calculates the common logarithm of the waveforms that have been assigned to Source1 and Source2
(the calculation is performed on “Source1/Source2”)
•
Log2: Calculates the common logarithm of the waveform that has been assigned to Source
• Sqrt1: Calculates the square root of the sum (or dif
ference) of the squares of the waveforms that have been
assigned to Source1 and Source2. This can be used to analyze displacement and tolerance.
•
Sqrt2: Calculates the square root of the waveform that has been assigned to Source
•
Cos: Uses the waveforms or logic signals that have been assigned to phases A, B, and Z to determine the
angle, and then calculates the cosine of this angle. You can use this to convert the angle to displacement.
•
Sin
: Uses the waveforms or logic signals that have been assigned to phases A, B, and Z to determine the
angle, and then calculates the sine of this angle. You can use this to convert the angle to displacement.
•
Atan
: Calculates the arc tangent of the waveforms that have been assigned to Source1 and Source2 (the
calculation is performed on “Source1/Source2”). You can use this to convert the displacement to an angle.
•
Electrical Angl
e: Calculates the phase difference between (1) the angle that was determined from the logic
signals that were specified for phases
A, B, and Z, and (2) the fundamental component that was determined
from the discrete Fourier transform of the waveform that was specified as the target. You can calculate the
phase difference (electrical angle) between the motor’s angle of rotation and the motor drive current.
•
Knock Filter (can be set only on the DL850EV): When the signal level of the waveform that has been set to
Source is less than or equal to the elimination level, the signal of this waveform is set to 0. You can select
whether to perform differentiation.
You can use this to extract knocking.
•
Poly-Add-Sub: Performs addition or subtraction or both on the waveforms that have been set to Source1,
Source2, Source3, and Source4. You can add or subtract the result of the power calculation, to calculate the
multi-phase power
.
•
Frequency: Calculates the frequency of the waveform that has been assigned to Source
• Period: Calculates the period of the waveform that has been assigned to Source
•
Edge Count
: Counts the number of slope edges of the waveform that has been assigned to Source. You can
use this to count the number of events in consecutive tests.
