Data Settings Required for Origin Search

3. Turn ON the PCU again or restart the Unit.
The data for the Common Parameters and Axis Parameters set in steps 1
and 2 above are enabled.
4. Start MECHATROLINK communications.
5. Set the Servo Parameters and save them.
Set the Servo Parameters required to execute origin searches.
To set parameters permanently, execute SAVE SERVO PARAMETER
(writes to the non-volatile memory)
To enable changed offline parameters, turn the power to the Servo Drive
OFF and then ON again or execute DEVICE SETUP.
For details, refer to 5-3 Transferring Servo Parameters.
6. Execute SERVO LOCK.
7. Set the data used for origin search.
Set the origin search speed data in the speed command value of the Axis
Operating Output Memory Area.
8. Execute ORIGIN SEARCH.
When using the PCU for the first time or to change the PCU parameter set-
tings, steps 1 to 3 must be performed.
To specify the Servo Parameters for acceleration/deceleration every time,
make sure that the axis operation is stopped (Busy Flag = 0) while changing
the acceleration/deceleration constants using WRITE SERVO PARAMETER.
Do not change the settings during axis operation. Changing parameters while
the axis is operating may result in incorrect positioning or other malfunction.
A simple explanation of the main parameters and data used to execute ORI-
GIN SEARCH is provided here. For details on the parameters required when
using absolute encoders, refer to 8-6 Absolute Encoder Origin.
To execute ORIGIN SEARCH, apart from the parameters explained here, the
following parameters also need to be set as basic settings for operating the
PCU.
• External I/O Signal Allocations
Refer to 6-4 Standard Settings for Servo Drives Using MECHATROLINK.
The origin proximity input signal must be allocated to execute ORIGIN
SEARCH.
• Command Unit
Refer to 7-2 Control Units.
The setting units for parameters and data depend on the specified com-
mand unit.
