■Using the control unit "degree"
• Current position/command position address
The current position/command position address is of the ring-address type.

• Software limit activation and deactivation settings
• After changing the "+" or "-" sign of an axis set with the software limit activated, perform a home position
return.
• When activating the software limit in an incremental system, perform a home position return after power-on.
When the unit is set to "degree", the software limit setting range is 0 degrees to 359.999 degrees.
When you set a value other than 0 degrees to 359.999 degrees in [Pr. PT15] to [Pr. PT18], the setting value is converted as
follows. (The value is clamped in a range from 0 degrees to 359.999 degrees.)
Software limit value
360.000 degrees to 999.999 degrees
-0.001 degrees to -359.999 degrees
-360.000 degrees to -999.999 degrees
When the software limit is enabled, set the software limit - ([Pr. PT17] and [Pr. PT18]) for the start position and the software
limit + ([Pr. PT15] and [Pr. PT16]) for the end 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
When the software limit is disabled, set the same values to the software limit - ([Pr. PT17] and [Pr. PT18]) and the software
limit + ([Pr. PT15] and [Pr. PT16]).
Control can be performed independently of the software limit setting.
