Setting the PCU
• An origin search can be carried out in single-direction mode using the CW/
CCW limit input signal as an origin proximity input signal.
• The origin is established by the first origin input signal after the CW or CCW
limit input switch is turned from ON to OFF.
The following example is an origin search operation in single-direction mode
using the CCW limit input signal. In this example, the CCW limit input is an N.C.
contact. With an N.O. contact, the logic is reversed.
1. When the operation start switch is turned ON, the origin search starts with
an origin search high speed of 500 pps in the CW direction on the X axis.
2. When the CCW limit input signal is turned ON, the program decelerates to
an origin search proximity speed of 100 pps.
3. When the first origin input signal is turned on after the CCW limit input signal
is turned ON, the pulse output is stopped and the origin is established.
