Hello markusgy,

Here official laungage of forum is English. However with help of Google translation I understand, your problem description is as follows.

I have a new MM440 but it says A0503 error. Unfortunately, first the phase sequence was not good in the outlet. It is very problem? I would like to use the slider with a live. Motor is not yet in the controller unconnected. What am I doing? Who can help me?

Now A0503 alarm is for undervoltage limit value.

Cause - Line supply has failed. 

line voltage & therefor DC link voltage is below defined limit value, check r0026.

Check input supply, does line contactor picks up correctly? Is the drive stored for quite long time? Does it requires capacitor forming etc. etc.?

German translation as below (Thanks Google)

HTH.
