POINT
In the absolute position detection system, rotating the shaft one revolution or
more during power-off may erase the home position. Therefore, do not rotate the
shaft one revolution or more during power-off. When the home position is
erased, [AL. 90 Home position return incomplete warning] will occur. Then,
execute the home position return again.
For the home position return, refer to chapter 18,19,20.
There are the following restrictions on [Pr. PA06 Number of gear teeth on
machine side] and the servo motor speed (N).
When CMX ≤ 2000, N < 3076.7 r/min
When CMX > 2000, N < (3276.7 - CMX)/10 r/min
When the servo motor is operated at a servo motor speed higher than the limit
value, [AL. E3 Absolute position counter warning] will occur.
