Precautions/
Remarks
This error occurs for axes for which the Servos are turned OFF for an axes group error to interlock the axes so that the
Servos cannot be turned ON with the MC_Power (Power Servo) instruction. This error occurs only when an immediate
stop of the command value and turning OFF Servo at same time (free-run stop) is specified for the Axes Group Stop
Method Selection.
Event name
Absolute Encoder Current Position Calculation Failed
Event code
64580000 hex
Meaning
It was not possible to correctly restore the current position from the absolute encoder information that was saved when
power was interrupted.

Prevention
•
The ring counter setting in the Con-
troller or the ring counter setting in
the Servo Drive settings was
changed.
•
The position to restore when con-
verted to pulses exceeded the
range of signed 40-bit data.
Reset the error and perform homing.
Perform homing near the position
where the absolute encoder is set up
so that the position to restore does
not exceed the range of signed 40-bit
data.
Perform homing again if you changed
any parameters related to position,
such as the modulo maximum posi-
tion setting value. Perform homing
near the position where the absolute
encoder is set up so that the position
to restore does not exceed the range
of signed 40-bit data. Also, do not
execute the MC_Power (Power
Servo) instruction or cycle the power
supply when the encoder position
exceeds the range of signed 40-bit
data.
