Number ContentsMessage
307 APC alarm: nth–axis battery low 1 nth–axis (n=1 – 8) axis APC battery voltage reaches a level where the
battery must be renewed.
APC alarm. Replace the battery.
308 APC alarm: nth–axis battery low 2 nth–axis (n=1 – 8) APC battery voltage has reached a level where the
battery must be renewed (including when power is OFF).
APC alarm .Replace battery.
309 APC ALARM:
n AXIS ZRN IMPOSSIBL
Return to the origin has been attempted without first rotating the motor
one or more times. Before returning to the origin, rotate the motor one
or more times then turn off the power.
