An attempt was made to return the reference position without
satisfying the condition that, when the tool is moving toward the
reference position with a positional deviation (DGN.300) of 128 or
more pulses, at least a one-turn signal is received.
Moreover, for the absolute pulse coder , a reference position return
was attempted without first turning the power off then on again
after rotating the motor one turn when the system is started, or
when the battery is replaced in response to a battery zero alarm.

Ensure that, after the occurrence o
a battery alarm (306) , the battery
was restored to its normal state, the
motor was rotated through at least
one turn , and that the power was
turned off then on again.
