Transferring Servo Parameters
Section 5-3
SAVE SERVO PARAMETER can be executed while the corresponding axis is
operating (Busy Flag ON). The following diagram shows the operation used to
save parameters to the W-series Servo Drive.
Timing Chart for Saving
Servo Parameters SAVE SERVO PARAMETER can be executed while the corresponding axis is
operating (Busy Flag ON).
When using Position Control Units with unit version 2.0 or later, any Servo
parameter save operations specified during an origin search will be performed
after the origin search has been completed.
SAVE SERVO PARAMETER, WRITE SERVO PARAMETER, and READ
SERVO PARAMETER cannot be executed on one axis at the same time.
• Saving Servo Parameters during Origin Searches for Position Control
Units with Unit Version 2.0 or Later
When execution of SAVE SERVO PARAMETER has completed, the Servo
Parameter Transferring Flag (word b, bit 14) turns OFF.

For a parameter size of two bytes, only the
rightmost word (word a+19) of the write data is
used, and the data in the leftmost word (word
a+20) is ignored.
The Servo Parameter Transferring Flag turns
ON for at least one cycle time when the
command to transfer the parameter is received.
The status of the Busy Flag does not change
when Servo Parameters are being written.
When using Position Control Units with unit version
2.0 or later, any Servo parameter save operations
specified during an origin search will be performed
after the origin search has been completed.
