4. HOW TO USE THE POINT TABLE
4 - 40
2) Software limit activation/deactivation setting
POINT
After changing the "+" or "-" sign of an axis with the software limit activation
setting, perform a home position return.
When activating the software limit in an incremental system, perform a home
position return after power-on.
a) Setting range
When the unit is "degree", the setting range of the software limit is 0 degree (lower limit) to
359.999 degrees (upper limit).
When you set a value other than 0 degree to 359.999 degrees in [Pr. PT15] to [Pr. PT18], the
set value is converted as follows. (It will be clamped between 0 degree and 359.999 degrees.)
Software limit value After conversion
360.000 degrees to 999.999 degrees
The remainder of the set value divided by
360
-0.001 degrees to -359.999 degrees The sum of the set value and 360
-360.000 degrees to -999.999 degrees
The sum of 360 and the quotient of the set
value divided by 360
b) When the software limit is activated
Set the software limit - ([Pr. PT17] and [Pr. PT18]) for the start position and the software limit +
([Pr. PT15] and [Pr. PT16]) for the target position.
The movable range is the section from - to + in the CCW direction.
