Details
The difference between the magnetic pole position after the phase Z has been passed (mag-
netic pole shift amount:SV028) and the initially detected position is excessive in the built-in
motor's incremental control system. The magnetic pole is controlled by the initial detection val-
ue.
- Reset method: Automatically reset once the cause of the warning is removed.

009F Battery voltage drop
Details
The battery voltage to be supplied to the absolute position detector is dropping.
00A3 In initial setup of ABS posn.
Details
This warning is detected until the axis reaches the reference position during the initial setup
of the distance-coded reference check function. This warning turns OFF after the axis has
reached the position, thus set the value displayed on the drive monitor to the parameter.
This warning is detected during the initial setup of MBA405W. This warning turns OFF after
the initial setup is completed by having the axis pass the Z-phase of MBA405W and turning
the NC power ON again.
