Overflow 1
The value that is obtained by dividing the
absolute encoder position (in pulses) by the
electronic gear ratio exceeded 2
31
(2,147,483,648) during the initialization of
position data.
*5
Review the operation range of the absolute
encoder position and the electronic gear
ratio.

• Check to see if the Linear Motor operates
according to the position command.
• Check on the force monitor to see if the
output force is not saturated.
• Adjust the gain.
• Maximize the Force Limit setting being
used.
• Wire the external encoder as shown in the
wiring diagram.
