6 Incremental Encoder Input Units
6 - 72 NX-series Position Interface Units User’s Manual (W524)
The parameter that is used to set up pulse period measurement is given in the following table.
This section describes the edge detection methods based on the differences between the input types:
phase differential pulse input multiplication x2/4, pulse
+
direction inputs, and up and down pulses.
 Phase Differential Input (Multiplication x2/4)
The period between phase-A input edges is measured regardless of the multiplier and count direc-
tion settings.
Parameter name Setting Default Remarks
Edge Detection
Method 0: Disable the function.
1: Measure every rising
edge.
2: Measure every falling
edge.
3: Measure every rising and
falling edge. 0 Changes are applied when the power sup-
ply to the NX Unit is turned ON or the NX
Unit is restarted.
