Wiring Section 3-4
Origin Input Signal (24 V)
Origin Input Signal (5 V) (Line Driver Input)
Positioning Completed
Input Signal The positioning completed input signal is also used as an origin search com-
pleted signal in modes 2 and 3. Adjust the setting of the Servo Drive so that
this signal always turns off while the servomotor is operating, and on when the
motor is stopped.
An origin search operation cannot be completed unless the positioning com-
pleted input signal turns ON after positioning has been completed.
3-4-4 Wiring Precautions
Operational errors such as dislocation can occur in most electronic control
devices if they are subjected to electronic noise from nearby power lines or
loads. Recovery from such errors is usually very difficult and time consuming.
