The following diagram shows the operation used to write parameters to the W-
series Servo Drive.
Timing Chart for Writing
Servo Parameters
WRITE SERVO PARAMETER can also 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 write operations specified during an origin search will be performed
after the origin search has been completed.
WRITE SERVO PARAMETER, READ SERVO PARAMETER, and SAVE
SERVO PARAMETER cannot be executed on one axis at the same time.

Busy Flag (Word b, bit 13)
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.
