Encoding Conditions (Encode Condition)
If the type of the encoding is ABZ or AZ, set the encoder’s pulse multiplier and the timing (edge) for counting
pulses. This setting is shared with the Rotary Angle operation.
Manual Reset (Manual Reset)
To manually reset the computed value, select Execute.
Arc Tangent (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.
atan(s1/s2)
s1 and s2: Sampling data
Math Source Waveforms (Source1 and Source2)
The options are the same as were described above for basic arithmetic.
Scaling (Scaling)
Select the unit that is used on the vertical scale. This setting is shared with the
operation. However,
there are no user-defined settings.
Quadrant Range (Quadrant)
Select the quadrant range to use for converting displacements to angles. This can be used on models with
firmware version 2.05 and latyer.
• Quadrant-2: −90° to +90° (−π/2 to +π/2)
Even if calculated result is between −180° and −90° or b90° and +180°, it is converted to an
angle between −90° to +90°.
• Quadrant-4: −180° to +180° (−π to +π)
Electrical Angle (Electrical Angle)
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.
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, set the scaling and the target on the setup menus explained later.
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. However, you can specify only the input channels of logic modules as math source waveforms.
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.
Scaling (Scaling)
Select the unit that is used on the vertical scale. This setting is shared with the Rotary Angle operation. However,
there are no user-defined settings.
Encoding Conditions (Encode Condition)
If the type of the encoding is ABZ or AZ, set the encoder’s pulse multiplier and the timing (edge) for counting
pulses. This setting is shared with the Rotary Angle operation.
