Example 3: Mode 2 Connection
In this example, as in example 2, a servo motor drive is employed and the
Z-phase of the encoder is connected to the origin line driver input terminal and
used as the origin input signal. OMRON U-Series and W-series Servo Motor
Drive are used.
In contrast to mode 1, the positioning completed signal (INP) of the servo motor
drive serves as both the origin search completed and the positioning completed
signals.
Set the servo motor drive so that the positioning completed signal turns OFF dur-
ing motor operation and ON while the motor is stopped.
An origin search operation cannot be completed if the positioning completed
input signal from the servo motor drive is not properly connected or set.
