Function

• If the axis command position or actual current position is above the FirstPosition and below the Last
Position (i.e., if it is in the specified zone) when Enable of this instruction is TRUE, the output variable
InZone will change to TRUE.
You can use ReferenceType (Position Type Selection) to set either the command position or actual
position as the axis information to monitor.
• You can perform zone monitoring for any axis type.
• If FirstPosition or LastPosition is changed while Enable is TRUE, the new value is applied in the
period in which it is changed.
• You can set multiple zones for one axis, and these zones can overlap. You can also set zones outside
the software limits.
