Okuma Alarm-P 0891 MCS Calculated current position lies outside range
An error occurred during calculation of APA.
Axis name or none (spindle)
1: Linear axis division stroke over
2: Semi-closed loop position [pr] -> [pf] conversion overflow
3: Underflow in composition
4: Overflow in composition
5: Hybrid control input overflow
6: Overflow in hybrid control initialization
Probable Faulty Locations
-Motor encoder and encoder shaft-mounted encoder,
-or absolute scale Control PCB of inverter unit
-Servo data file
Pay sufficient attention for the following alarm numbers.
1, 3: Sensor zero offset is often incorrect.
4 : Servo data file is often faulty.
5, 6: Motor coupling is often loose.
