-My machine have 5 motor connect to 5 Inverter Micromster 440, (Name motor is M1, M2, M3,M4,M5) all motor control by the PC through profibus COM link.

-When I run 5 motor so all motor run ok .

-When I run only motor M4 so this motor run ok too

-But when stop motor M4 and run 4 other motor ok , I get fault F0422 on Inverter of motor M4, why Inverter M4 get  fault  like that ? although Inverter M4 was Stop in this task.

-Note : Inverter M4 is new one I just replace for old one, when I replace I was use AOP panel to copy all parameter from old one to new one. I has success some time with copy and paste parameter like that for other inverter but this time is fail .

-Can you give me the way to delete this fault F0422.

Split from MM440 > F0422.

Hello,

Significance of F0422 - No load applied to inverter.

Please check when you applied run command to other motors, check status of control word of M4 drive. Since you mentioned replacement of drive & restoring of parameters via AOP, some changes in parameters might be causing triger of F0422.
