• When logic sources are turned off
Set the input channels for the phase A, B, and Z signals,
1
the signal level of each signal that you will count as
a pulse,
2
and the hysteresis of each signal.

• Phase A (Phase A): Set the input channel, signal level, and hysteresis of the phase A signal.
• Phase B (Phase B): Set the input channel, signal level, and hysteresis of the phase B signal.
• Phase Z (Phase Z): Set the input channel, signal level, and hysteresis of the phase Z signal.
To set the timing that pulses are counted and the timing that the pulse count is reset for the signal level that
you set here, see “Encoding Conditions” later in this section.
1 The options are the same as were described above for basic arithmetic. However, you cannot select input
channels of frequency modules or real time math channels (RMath).
2 The signal level range is the same as the trigger level range.
3 The hysteresis level is the same as the trigger hysteresis.
If the type of the encoding is absolute 8 bit, absolute 16 bit, or gray code
Select the input channel of the logic module. For absolute 16 bit and gray code encoding, set the logic channel
for the least significant digits to Source1 and the logic channel for the most significant digits to Source2.
* When the bit length of Gray Code is 8 or less, the Source2 setting is ignored.
Negative Logic ON/OFF (Negative logic)
Select which bit state will be recognized to be logic I.
• ON: Negative logic (low state is logic I)
• OFF: Positive logic (high state is logic I)
Pulses per Rotation (Pulse/Rotate)
Set the number of pulses per rotation.
Range: 1 to 65535. The default value is 180.
Bit Length (Bit Length)
When the bit length (Bit Length) encoding type is set to Gray Code, set the bit length.
Selectable range: 2 to 16
Scaling (Scaling)
Select the unit that is used on the vertical scale.
• Radian: Radian
• Degree: Degrees
• User-defined (User Define): Set K, the size of the scale.
Range: −9.9999E+30 to +9.9999E+30. The default value is 1.0000.
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.
Count Conditions (Count Condition)
You can select the encoder’s pulse multiplier from the following options.
×4, ×2, ×1
When the multiplier is ×4, regardless of the timing setting made in the next section, pulses are counted on all the
edges of the signal.
