Homing Operation
This section describes the operation of the supported homing methods.
 Homing Methods 8 and 12: Homing by Origin Proximity Input and Origin
Signal
These Homing methods use the Origin Proximity Input that is enabled only in some parts of the drive
range, and stops when an origin signal is detected.
An origin signal is detected in the positive direction for Homing method 8 and in the negative
direction for Homing method 12.
The operation start direction of the homing operation is the same as the direction of detection of the
origin signal when the Origin Proximity Input is OFF, and the reverse direction when the Origin
Proximity Input is ON.
The operation direction reverses for the positive drive prohibition input.

A homing error (Home error) 1 will occur in the following cases.
• When the drive prohibition inputs on both sides are ON at the same time.
• When the drive prohibition input of one side is ON, and the drive prohibition input of the other side
is turned ON without detecting the rising edge of the Origin Proximity Input.
