Why do you want to run the motor in the delta configuration? The VFD will change the speed to anything you want to do. The delta and Wye connections are normally used to change the speed of a motor. That's what the VFD is for...??

Micromaster 440, a few seconds after i power up, F0022 appears


This is most likely a fault with the IGBT even if it meters out correctly.
They can be replaced but the cause cause of the fault in the first place may still be present and might damage it again.
Occasionally there are further issues from faults like this so I would give some thought to doing a service exchange with a repair company.

Likely to be IGBT fault. Unless its a large drive I would service exchange it or bin it. Not worth the hassle.

How to get a siemens micromaster 440 up and running


Hello Stephen The first thing you have to do is make sure that the motor is connected for 220 volt three phase How do you know? your motor must have this connection info on the name plate It must show 220v Delta connection and 380 or 400 v star connection. connect your motor in Delta ie the motor connection links are connected from U 1 to V2, U1 to W2 and V1 to U2. Ok Now for the restof it You have asmall book that came with the inverter so go to page 9 and you will see the drawing for mm440 at the bottom you will see the connection for the speed pot. which is 1,2,3,4, wire in as shown make sure the wiping connection is in 3..now wire in a switch across 9 which is the common and 5 this starts and runs the inverter when you open the switch the inverter will ramp down and stop.... IF YOU look at page 8 it shows how delta and star is connected at the motor..... now go to page12 for this you must have the power on to the inverter.. as you enter the parameters they come up in sequence as you enter the info...on par 700 put in 2 also at 1000 put in 2 set p1080 at 0.0...p 1082 at 50 P3900 at1 This should get you up and going
