11.17.4.1 (ID 1027) Autochange
Location in the menu: P3.15.6
Use this parameter to enable or disable the rotation of the start sequence and the priority of motors. The autochange changes the
sequence in which the motors start to wear the motors equally.
The monitoring values V2.10.7 Pump 1 Running Time – V2.10.14 Pump 8 Running Time count the run-time of the motors. The au-
tochange function sets the start sequence according to the run-times. The motor that has the lowest running hours starts first and
the motor that has the highest running hours starts last.

Example
After an autochange, the first motor is put last. The other motors move up 1 position.
The start sequence of the motors: 1, 2, 3, 4, 5
--> Autochange -->
The start sequence of the motors: 2, 3, 4, 5, 1

Description
In normal operation, the sequence of the motors is always 1, 2, 3, 4, 5. The sequence can change
during the operation if interlocks are added or removed. After the drive stops, the sequence al-
ways changes back.
The system changes the sequence at intervals to wear the motors equally. The intervals of the
autochange can be adjusted with parameter P3.15.8. The timer of the autochange interval oper-
ates only when the Multi-pump system operates.
The start sequence changes at the selected weekday and time of day. Make the selection with
parameters P3.15.9 and P3.15.10.
To use this mode, an RTC battery must be installed in the drive.
