[Adjustment items after replacement]
When replacing the servo amplifier, it is necessary to set the axis selection with the rotary switch
(SW1) on the servo amplifier of each axis.
Open the front cover of the servo amplifier and turn the rotary switch (SW1) for the axis selection
so that the arrow mark indicates the following set value.
Make sure that the DIP switch (SW2) is OFF.
After the adjustment has been completed, turn ON the power to the main unit and turn it OFF.
After that, restart the operation.
Note. When the main unit is started up for the first time after the servo amplifier has been
replaced, do not perform the origin return.
