Memory Protect/Release
This operation can be used to protect or release the memory protection in the
MC Unit.
Procedure
Use the following procedure to protect or release memory protection.

The initial setting is for the memory to be protected.
2. Select “protected” or “released” using the Up or Down Key.
When the Up or Down Key is pressed, the display will toggle between “pro-
tected” and “released.”
Note If the TEACH Key is pressed while the memory is protected, the following display
will appear.

Initial Setting of the Absolute Encoder
This operation is used to perform initial setting for the absolute encoder for a
specific axis or all axes.
Note This procedure is only supported for the CV500-MC221/421 and C200H-
MC221.
The compensation value for the absolute encoder is read, and the present posi-
tion is moved to the mechanical origin (absolute value “0”). Use this procedure to
write the initial settings values for the absolute encoder into the system parame-
ters.
Initial setting is used at the following times:
•
When changing the mechanical origin.
•
When using a Servodriver with an absolute encoder for the first time.
•
When present position values are lost due to battery discharge during normal
operation.
•
When the absolute encoder malfunctions.
•
When replacing a Servomotor mounted with an absolute encoder.
Note For details regarding the operations necessary to set multiple rotation data for
the absolute encoder to “0,” refer to the relevant Servodriver manual.
The initial settings procedure is used at the Servodriver (OMRON U Series), im-
mediately after setup.
When this procedure is performed, the position at which an axis using the abso-
lute encoder is at rest will be registered as the mechanical origin.
Once the mechanical origin has been established, it will never be necessary to
perform initial settings again. As a safety precaution, this function can be pro-
tected by setting DIP switch pin1 on the MC Unit to ON. In this protected state, if
an attempt to perform this function is made, an error will be generated.
