The voltage level of the battery is
higher than the specified voltage
( > 3.8V). Maybe an electrical
charge still remains in the servo
drive.
An absolute position error within
one turn.
The recorded turn numbers are
lost as the voltage level of battery
is too low or after a power
interruption.
The voltage level of the battery is
lower than the specified voltage.
The normal range of turn
numbers of absolute position is -
32768~+32767.
A timing error occurs when
reading the data of absolute
position via the digital inputs and
outputs.
Possible an incremental type
motor is connected.
Possible the setting value of P2-69
is not set to 0.
Position counter overflow occurs.
