Application Examples
Section 11-3
Example: First Part of Default Settings Read from an OMRON W-series Servo
Drive
Note All of the data is expressed in hexadecimal.
For example, the data in E1_01024 to E1_01027 indicates parameter Pn100,
a parameter size of 2 bytes, and a set value of 0050 hex (80 decimal).
This data format is also used in the sample program when writing or saving
data from the CPU Unit's EM Area to the Servo Drive. (The parameter size at
the end of the transfer data is 0000 hex, which is the end code.)
Consequently, this program can be used to read the Servo Parameters to the
CPU Unit's EM Area to back up the Servo Parameters and those Servo
Parameters can be transferred to a new Servo Drive if it is necessary to
replace the Servo Drive in the future.
This sample program will start transferring the Servo Parameters when the
Servo Parameter Batch Transfer Bit (CIO 510.00) is ON and W303.03 has
been turned ON (indicating that axes 1 and 2 are both communicating nor-
mally) by the application example shown in
11-3-1 Initial PCU Settings .
When this program is completed (Servo Parameter Transfer Complete),
W500.05 is turned ON for one cycle. If an error occurs while the Servo Param-
eters are being transferred (Error Flag ON), the transfer will be cancelled at
that point and W500.10 will be turned ON for one cycle.
Sample Ladder
Program
The Write Servo Parameters, Read Servo Parameters, and Save Servo
Parameters functions for axis 1 (program steps 000016 to 000033) are the
same as the functions described in
11-2-3 Transferring Servo Parameters .
The functions for axis 2 (program steps 000034 to 000051) are the same as
the functions for axis 1, except for the different I/O words. To prevent duplica-
tions, be sure to change the axis 1 output words (CIO 0000 to CIO 0024) to
the corresponding axis 2 output words (CIO 0025 to CIO 0049) and change
the axis 1 input words (CIO 1000 to CIO 1024) to the corresponding axis 2
input words (CIO 1025 to CIO 1049).
