Why might an ATV930 not Autotune?
Issue:
Cannot perform an auto tune on a ATV930 drive.
Product Line:
Altivar ATV930 ATV950
Environment:
All models
Cause:
Setting Autotuning to "Apply Autotuning" results in "No action"
Resolution:
Sometimes, the drive's configuration can prevent an Autotune.
For instance, if the drive’s command channel is from a communication network such as Modbus, then a specific command word order must be sent before performing tuning with the keypad.
1- Power on the drive, and ATV930’s state is NST
2- Write CMD = 6, and ATV930’s state is RDY
3- Write CMD = 7, and ATV930’s state is RDY
4- With the keypad, make “Autotuning” = “Apply Autotuning”, the tune isn’t done
5- Write CMD = 271, and ATV930’s state is RDY
6- With the keypad, make “Autotuning” = “Apply Autotuning” then the tune is done
Another possibility is when the drive status is NST.
For instance, if the drive is set for 3-wire control and DI1 is not active, the status will be NST, and an Autotune is not allowed.
