2.9.3 Battery Error Code
When a position detector error including battery error has occurred, the following
error code is shown on the error display.
8–401 Axis1 Encoder abnormal
8–402 Axis2 Encoder abnormal
8–403 Axis3 Encoder abnormal
8–404 Axis4 Encoder abnormal
8–405 Axis5 Encoder abnormal
When a battery alarm has occurred, the following error code is shown on the error
display. When the following error code is shown in the error history at generation of
a position detector error, the error can be identified as the battery error.
1–401 Axis1 Battery alarm
1–402 Axis2 Battery alarm
1–403 Axis3 Battery alarm
1–404 Axis4 Battery alarm
1–405 Axis5 Battery alarm
The battery error is one of the position detector errors (i.e., encoder errors), and there
is other cause leading to the position detector error. The restoring method from the
position detector error varies with the error contents generated. To properly execute
the restoring method from the position detector error, therefore, read through and
completely understand the descriptions carried in Section 4.
