Scaling (Scaling)
Select the unit that is used on the vertical scale.
• Seconds (Second): The unit is seconds.
• Hours (Hour): The unit is hours.
Common Logarithm (Log1 and Log2)
• Log1: Calculates the common logarithm of the waveforms that have been assigned to Source1 and Source2
(the calculation is performed on “Source1/Source2”).
K • log
10
(s1/s2)
K: Coefficient. s1 and s2: Sampling data.
• Log2: Calculates the common logarithm of the waveform that has been assigned to Source.
K • log

(s)
K: Coefficient. s: Sampling data.
Math Source Waveforms (Source1, Source2, and Source)
The options are the same as were described above for basic arithmetic.
Coefficient (K)
Set scaling coefficient K.
Range: −9.9999E+30 to +9.9999E+30. The default value is 1.0000.
Square Root (Sqrt1 and Sqrt2)
• Sqrt1: Calculates the square root of the sum (or difference) of the squares of the waveforms that have been
assigned to Source1 and Source2. This can be used to analyze displacement and tolerance.

Sign (Sign)
Set the operator between s1
2
and s2
2
in Sqrt1.
• +: Addition
• −: Subtraction
Cosine (Cos) and Sine (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 cosine or sine of this angle. You can use this to convert the angle to displacement.
Type (Type)
Select the type of the encoding. The settings other than the Resolver Ch setting are shared with the
operation. You can specify the Resolver Ch setting when there is a channel that has been defined with the
resolver function of real time math.
• If there are multiple channels that have been defined with the resolver function, select Resolver Ch, and then
select the channel.
• If Resolver Ch has been selected, the setup menu explained later is not displayed.
Source Conditions (Source Condition)
Set the conditions of the source whose pulses you want to count. This setting is shared with the Rotary Angle
operation.
Pulses per Rotation (Pulse/Rotate) and Bit Length (Bit Length)
Set the number of pulses per rotation. When the encoding type is set to Gray Code, set the bit length. This
setting is shared with the Rotary Angle operation.
