(b) Degree unit
When the unit is set to "degree", the setting range of the current position latch is from 0 degree
(upper limit) to 359.999 degrees (lower limit).
When you set a value other than 0 degree to 359.999 degrees in the current position latch +/- [Pr.
PC66] to [Pr. PC69], the set value is converted as follows.
Current position latch range After conversion
360.000 degrees to 999.999 degrees (Setting value) % 360
-0.001 degrees to -359.999 degrees 360 + (setting value)
-360.000 degrees to -999.999 degrees (setting value) % 360 + 360
The valid range of the current position latch varies depending on the setting of the upper and lower
limits.
The valid range remains unchanged even if the rotation direction is reversed.

To enable the current position latch function of section A in the figure, set the parameters as follows:
Current position latch range -: 315.000 [degrees] ([Pr. PC68]: 0, [Pr. PC69]: 315)
Current position latch range +: 90.000 [degrees] ([Pr. PC66]: 0, [Pr. PC67]: 90)
To enable the current position latch function of section B in the figure, set the parameter as follows:
Current position latch range -: 90.000 [degrees] ([Pr. PC68]: 0, [Pr. PC69]: 90)
Current position latch range +: 315.000 [degrees] ([Pr. PC66]: 0, [Pr. PC67]: 315)
