8 Pulse Output Units
8 - 74 NX-series Position Interface Units User’s Manual (W524)
The specifications of the pulse outputs and the pulse output waveforms of the Pulse Output Unit are
given below.
• The ON width is width A in the above figure.
• The OFF width is width B in the above figure.
• The rising width and falling width are not specified.
Precautions for Correct Use
• The pulse widths during actual usage may be smaller than the specified values due to pulse
waveform distortion caused by the impedance of the connecting cable.
• If the output current is too small when the pulse output speed is high, a sufficient signal width
may not be provided for the input specifications of the motor drive or other input device. If
that occurs, connect bypass resistance or take other steps to increase the output current and
obtain a sufficient signal width.
