Note
•
Make sure that the function-specific script files you use is downloaded from the previous
Internet address. Otherwise, alarm A650 may appear reminding you that this script is not
an officially released script. Also, you can download the "SINAMICS V20 Inverter
Operating Instructions" from the link.
•
You can obtain the "SSTAGE.bin" file from the corresponding firmware updating package.
Make sure that the version of the firmware updating package to be downloaded and the
version of your V20 firmware are the same.
•
After you successfully download the script files into the inverter, all parameters used for
this function are automatically set to their default settings. Note that the default settings of
parameters P0731, P0732, P0733, P0734, P0840, P0845, P1200, and P2200, which are
different from their factory defaults, are changed to adapt to the function. To make sure
that the multi-pump control function runs properly, do not manually set the values of
P0840 and P0845 after the function is enabled.
•
Multi-pump control uses PID controller-specific parameters. For more information about
how to configure those parameters, see Section "Setting the PID controller" in
"SINAMICS V20 Inverter Operating Instructions".
•
If you use the motor staging function on the inverter, this function is automatically
disabled after the multi-pump control function is enabled.
