Okuma Alarm-C 3191 MCS Calculated current position lies outside range


Okuma Alarm-C 3191 MCS Calculated current position lies outside range
An error occurred during calculation of APA value.

Object
Axis name or none (spindle)

Character-string
None

Code
XXXXXXXX
1: Linear axis divided travel over
2: Overflow during conversion of semi-position from [pr] to [pf].
3: Underflow in synthesizing the axis data
4: Overflow in synthesizing the axis data
5: Overflow of input values used for hybrid control
6: Overflow during initialization for hybrid control

Probable Faulty Locations
– Motor encoder, encoder with shaft, or ABSO SCALE
– Inverter unit control board
– Servo data file
If the alarm code is “1” or “3”, the position encoder may not be properly offset to zero.
If the alarm code is “4”, the servo data file may be defective.
If the alarm code is “5” or “6”, the motor coupling, encoder with shaft, or ABSO SCALE may be loosely mounted.
