Error
Initialization of internal position data was not
processed correctly in semi-closed control
mode and absolute value mode.
• Provide the required encoder power
supply voltage 5 VDC ±5% (4.75 to
5.25 V). Be careful especially when the
encode cable is long.
• If the Servomotor cable and the encoder
cable are bundled together, separate
them.
• Connect the shield to FG.

Error
Initialization of internal position data was not
processed correctly in fully-closed control
mode and absolute value mode.
• Provide the required external encoder
power supply voltage 5 VDC ±5% (4.75 to
5.25 V). Be careful especially when the
external encoder connection cable is long.
• If the Servomotor cable and the external
encoder connection cable are bundled
together, separate them.
• Connect the shield to FG. Refer to the
external encoder connection diagram.

Error 1
Electronic gear ratio exceeded the allowable
range.
Check the object settings. The electronic
gear ratio must be set between 1/1000 and
1000.

Error 2
External encoder ratio exceeded the
allowable range.
Check the object settings. The external
encoder ratio must be set between 1/40 and
160.

Error
The set value of the External Feedback
Pulse Type Selection (3323 hex) differs from
the external encoder type that is actually
connected for serial communications.
Electronic gear ratio exceeded the allowable
range.
Set object 3323 hex to conform with the
external encoder type that is actually
connected.
