Operation
9.3 Controlling via the AOP30 operator panel
9.3.5.5 AOP30 diagnostics
Software/database version
This menu command shows the versions of the software and database.
The database version must be compatible with the drive software version (refer to
parameter r0018).
Database contents
Shows detailed information on the drive objects (DOs) present in the system
Battery status
This menu displays the battery voltage (in volts and as a bar chart). The battery ensures that
the data in the database and the current time are retained.
When the battery voltage is represented as a percentage, a battery voltage of ≤ 2 V is equal
to 0%, and a voltage of ≥ 3 V to 100%.
The data is secure up to a battery voltage of 2 V.
● If the battery voltage is ≤ 2.45 V, the message "Replace battery" is displayed in the status
bar.
● If the battery voltage is ≤ 2.30 V, the system displays the following message: "Alarm,
weak battery".
● If the battery voltage is ≤ 2 V, the system displays the following message: "Caution:
The battery is dead".
● If the time and/or database are unavailable due to lack of voltage after a prolonged
system downtime, the loss is established by means of a CRC check when the system is
switched on again. This triggers a message instructing the user to replace the battery and
then load the database and/or set the time.
For instructions on how to change the battery, see "Maintenance and servicing".
Keyboard test
On this screen, you can check that the keys are functioning properly. Keys that you press
are represented on a symbolic keyboard on the display. You can press keys in any order you
wish. You cannot exit the screen (F4 – "Back") until you have pressed each key at least
once.
Note
Alternatively, you can exit the keyboard test screen by pressing any key and holding it down.
LED test
On this screen, you can check that the 4 LEDs are functioning properly.
Database statistics
Data related to the database is displayed here (e.g. free memory for additional DOs).
