•
: Calculates the angle of rotation from the sine signal and cosine signal that are generated from the
detection coils of the resolver depending on the angle of the rotor.
•
: This can be used to filter the waveform that has been set to Source with the same characteristics of
the IIR filter of the digital filter. You can set the frequency to values over a wider range than is available with
the IIR filter of a digital filter.
•
: Integrates a pulse width modulation signal and demodulates it to an analog signal.
•
: Calculates the reactive power from apparent power and effective power.
•
: Detects the fram of the CAN bus signal with the specified ID.
•
Measures the frequency of the pulse frequency output torque sensor and calculates the torque using
the specified coefficient.
* Resolver, IIR filter, and PWM can be used on models with firmware version 2.00 and later.
Reactive Power(Q) and CAN ID can be used on models with firmware version 2.05 and later.
Turning the Mean On and Off (Mean)
Select whether to perform the mean. This mean is the same feature as the one in the digital filter. However, the
number of taps is fixed to 32. The sampling frequency is the same as the DL850E/DL850EV sample rate. The
maximum sampling frequency is 10 MHz.
• ON: The mean is performed.
• OFF: The mean is not performed.
Optimizing Value/Div (Optimize Value/Div)
Press the Optimize Value/Div soft key to automatically set the value/div that the DL850E/DL850EV determines is
the most appropriate for the math source waveform range and the expression. The selected value is from among
the 123 value/div options for vertical axis sensitivity.
• The automatically selected option does not line up with the input values and math results, so you need to use
the SCALE knob to change the value/div.
• There are a total of 123 value/div options within the following range: 500.0E+18 to 10.00E−21 (in steps of 1, 2,
or 5).

Unit (Unit)
You can assign a unit of up to four characters in length to the math results. The specified unit is reflected in the
scale values.
All Channels Setup Menu
There is a menu (ALL CH) that is used to configure the settings for all channels for real time math. The menu is
operated in the same way as the
all channels setup menu on the standard model
.
• You can configure the real time math settings of all channels while viewing the settings in a list.
• You can turn real time math on and off for all channels at once.
• There are some items that cannot be configured from the ALL CH menu.
