Maint status
(*1) These follow the setting and display unit (#1003 iunit) of the 1st part system.
(*2) Synchronous tapping error
This displays the maximum values of the synchronous tapping error that occur during the synchronous tapping.
The synchronous tapping error means the motor tracking delay for the commanded positions of the spindle and the
tapping axis.
The positive synchronous tapping error means that the tapping axis is delayed responding to the spindle, and the neg-
ative synchronous tapping error means that the spindle is delayed responding to the tapping axis.

This displays the motor end detector serial No.
This displays the machine end detector serial No.
It displays the motor type which is set for the spindle specification parameter "#3138 mo-
tor_type".
The maximum of 26 words are displayed with 2 lines and left aligned.
This displays the READY ON work time. (Units: 1 hr)
This displays servo alarms that occurred in latest order with the following formats.
Time: Work time when the alarm occurred
Alarm No.: Number of the servo alarms that occurred
This displays the maintenance dates.
Year: One digit
Month: 1 to 9, X (Oct.), Y (Nov.), Z (Dec.)
This displays the maintenance status.
This outputs the data of which absolute value is the largest among the synchronous tapping
error width (-99999.999 to 99999.999 mm) during the synchronous tapping modal.
This data will be initialized to "0" when entering the synchronous tapping modal or restoring
the power. Other than that, the data continues to display the maximum value.
