4. HOW TO USE THE POINT TABLE
2) Software limit activation/deactivation setting
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. (The value after conversion will be inside the range of 0
degree to 359.999 degrees.)
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.
Set the movable range of section A as follows.
Software limit - ··· 315.000 degrees
Software limit + ··· 90.000 degrees
Set the movable range of section B as follows.
Software limit - ··· 90.000 degrees
Software limit + ··· 315.000 degrees
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.
