Origin Compensation Value
The origin compensation value setting determines the amount of adjustment
that is applied when adjustment is necessary after the origin has been deter-
mined (e.g., if there is inaccuracy in the position at which the proximity sensor
turns ON or if the motor has been changed). After the origin is initially detected
using origin search, the number of pulses specified with this setting are output,
the present position is set to 0, and at the same time, the origin is established
(the No Origin Flag turns OFF).
Setting range: C0000001 to 3FFFFFFF Hex (--1,073,741,823 to 1,073,741,823)
The operation patterns that are determined by the above settings are illustrated
on the following pages.
6-4-3 Operation Mode Settings
An open collector output signal such as a sensor is connected to the origin input
signal (A14, A15/B14, B15), and the origin input signal response time is 0.1 ms.
(N.O. contact setting)
In this mode, an origin input signal error (error code 6202) will be generated if an
origin input signal is input during the deceleration from origin search high speed
to origin search proximity speed which is initiated by the input of an origin prox-
imity input signal (or a limit input signal if the origin detection method is set to 3).

Origin input signal error (error code 6202)
The Z-phase signal from the servo drive is connected to an origin input signal
(A14, A15 [A16]/B14, B15 [B16]). An origin input signal is input and, within an
interval of approximately 20 ms after the stop, a error counter reset signal is out-
put.
Approx. 20 ms

In this mode, if an origin input signal is input during the deceleration from origin
search high speed to origin search proximity speed which is initiated by the input
of an origin proximity input signal, positioning will be stopped by the first origin
input signal after the deceleration has been completed.
