Hello,

I completed the commissioning of a unit made of these modules:

1. ACTIVE INTERFACE MODULE (6SL3300-7TE41-4AA1)

2. ACTIVE LINE MODULE (6SL3330-7TE41-0AA3)

3. MOTOR MODULE (6SL3320-1TE41-0AA3)

4. CU320-2PN (6SL3040-1MA01-0Axx)

Everything works fine, but after a power cycle of the whole unit I cannot start the line module because parameter p10 of it is "[1] Quick commissioning". So, I need to get online and change it manually through StartDrive to "[0] Ready". I already tried to set p10 to "[0] Ready" and save RAM data retentively, but it does not fix the problem.

Thanks in advance for your help.

You need to save data in non volatile memory & not in RAM.

Have you set p0977 = 1 i.e. save data in non volatile memory, after setting p3900 = 3?

So that CU will understand that quick commissioning is completed & data is saved in non volatile memory.  

The root cause of this issue was active interface module booting up too late. Its 24 VDC power supply was coming on at a different time. While the CU was starting the active interface module was OFF, thus leading to p10 being set to 1.

After changing the power supply of the active interface module (so that it boots up together with the CU) parameter p10 remains at zero (Ready).
