Initial Setting of the Absolute Encoder
Procedure
1, 2, 3...
66
This procedure has the following restriction:
Initial setting cannot be performed if the present position registered in the abso-
lute encoder has an absolute value exceeding 32,767 pulses.
After setup, if the motor is rotated, the value may exceed 32,767 pulses. In this
case, perform the initial setting procedure once again after either setting up the
Servodriver again, or moving the motor close to the position after setup.
Note Before performing this procedure, it is necessary to set DIP switch pin 1 on the
MC Unit to OFF.
If "5.ABS INIT SET" is selected in EXTENSION mode with DIP switch pin 1 ON,
the following display will appear:
TURN OFF
DIP SW No.1 AND
THEN PROCEED.
Press the CLR Key to return to the EXTENSION mode menu. After releasing
memory protection by selecting "4.MEM PROTECT," re-attempt the procedure.
Use the following procedure to perform initial setting for an absolute encoder.
Note After completion of initial setting, as a safety precaution, perform backup for the
system parameters using MC Support Software.
1. Select "5.ABS INIT SET," from the EXTENSION mode menu.

2. Select the axis or axes for which servo-unlock is to be executed.
In this example, all axes are selected.
EXT| ABS IN SET
| OK?
ALL|
0
| YES / NO
Indicates selected axes as follows:
ALL: All axes; X: X axis; Y: Y axis; Z: Z axis; U: U axis
3. Press the YES Key to perform initial setting.
The initial setting values will be read into the system parameters.
When the operation has been completed, the following display will appear.
EXT| ABS IN SET
|
ALL| COMPLETE!
YES
|
This display will appear even if initial setting is accidentally performed for an
axis not using an absolute encoder. In this case, however, the initial setting
values will not be read into the system parameters.
Note When using the C200H-MC221, the initial setting values will be
stored in the internal memory. For this reason, if the power supply for
the MC Unit is turned OFF, the initial setting will return to the original
values. Save the parameters by writing them to flash memory.
