6-4-5 Operation Pattern With Origin Compensation
An origin compensation value can be set so that the axis is moved by that
amount after the origin input signal is detected. That origin compensation move-
ment will be executed at the origin search proximity speed.

Note
If the speed at the time of the compensation is below the initial speed, there will
be no acceleration or deceleration for the compensation pulse output. If that
speed is at least equal to the initial speed, there will be acceleration and decel-
eration.

The override is not enabled with respect to pulse output during origin search, but
it is enabled with respect to the amount of pulse output set for origin compensa-
tion.
In this case, the origin search proximity speed corresponds to an override setting
of 100%. Therefore, if the override is set to 200%, pulse output for the origin
compensation value is made at twice the speed of the origin search proximity
speed, as shown below.

Note
1. If the speed during movement for compensation is greater than the initial
speed as a result of the override, there will be acceleration and deceleration
with respect to the pulse output.
2. When using an OMNUC W-series model, even if an origin compensation
value is not set, the position of the origin can be adjusted at the Servo Drive.
For details, refer to the relevant W-series manual.
