2.7 Search origin
<3/3/A8>
The <3/3/A8 SEARCH ORIGIN> command returns each axis to its origin
position. After power is turned on, return-to-origin must be performed
before beginning any work.
This command is also provided in the MANUAL mode of each application
manager. To perform return-to-origin again after having performed it once,
line up the cursor with <3/4/B6 INIT. SERVO ORIGIN> and press the
[SHIFT]+[ENTER] keys. The machine reference for each axis also appears
on the operation monitor after return-to-origin is complete.
Machine reference
The built-in motor encoder of each axis issues a “0” pulse each time one
rotation is complete. When return-to-origin is performed, there will be a
difference in distance between the position where the origin signal is
detected and the point at which the next encoder “0” pulse is received
(origin position is actually set). This is called the machine reference and is
usually expressed as a percentage, with 100% being equal to one full
rotation of the motor. The machine reference value must be in the range
from 35% to 65%.

NOTE
The machine reference of each axis is preadjusted at the factory prior to shipping. It is
unlikely that you will need to readjust these values under normal operating conditions. If
readjustment is required, please contact your YAMAHA sales office or dealer.

3.1 Software limits
When you select <3/3/B1 ADJUST TARGET> - “Soft Limit”, the Software
Limit screen opens as shown below. You can check and adjust here the
software limit parameters to determine the axis movement range and initial
position parameters used as a reference point for axis movement.
These parameters must be set correctly to maintain accurate machine
movement and component mounting.
