Avantra 44 nip motor problem

Hello.
I have a problem with nip roller motor which is not working.
Checked so far:
1. Motor
2. Motor cable
3. SDM
4. Flat from DEC to SDM.
Still no 24V on the motor, nor on SDM output.
Unidiag gives "command error" when testing this motor.
Avdiag gives "APIS command error" when testing this motor.
Any ideas except "replace DEC"?
Cheers, Chris

Hi sir:
If you do not have +24Vdc coming from SDM output, measure the input from SDM, if there are and NOT output the SDM is faulty.
Of course if you do not have input in SDM, you must track where the Voltage is Missing before to arrive to the SDM, look for the schematic diagram, where is the exactly voltage for the Input SDM.
Lookf for ;1) loose wires, 2) broken wires 3) faulty connector, 4) edge connectors of board, 5) dry and cold solder joint in the board SDM( very important) and resolder if that is the case, most of the 75% electronic failure is coming by that faulty.
Let me know.

24V to SDM comes from DEC via flat cable. It is present. Anyway, I will try another DEC next week.

ok .
However you must test the output from SDM for Motor

Lookf for ;1) loose wires, 2) broken wires 3) faulty connector, 4) edge connectors of board, 5) dry and cold solder joint in the board SDM( very important) and resolder if that is the case, most of the 75% electronic failure is coming by that faulty.

Let me know.

It is not an issue of SDM module for sure. Tested with 2 other 100% functioning modules.
Broken SDM does not give "apis command error" message.

However how is You have 24 in the terminal of Motor coming from the Board??

Lookf for ;1) loose wires, 2) broken wires 3) faulty connector, 4) edge connectors of board, 5) dry and cold solder joint in the board relationed ( very important) and resolder if that is the case, most of the 75% electronic failure is coming by that faulty.
