Action 2: This alarm is issued when the difference between the motor
position and separate detector position exceeds the
excessive semi-full error level. Check if the conversion
efficient for dual position feedback is set correctly. If the
conversion efficient is set correctly, increase the alarm level.
If this alarm is still issued after the level is modified, check
the connection direction of the scale.

[Setting] Detection unit. When 0 is set, no detection is made.
Action 3: The current offset value of the current detector (equivalent
to the current value in the emergency stop state) is
abnormally high. If this alarm is still issued after the power
is turned off then back on, the current detector is faulty. For
the αi series, replace the amplifier.
