I have some problem to excute MAM and MAJ, sometimes it shows "execute on an axis whose servo loop is not closed" and MAM error is 5: servo off state error. Is anyone know what's means for open or close servo loop, how to do that?

Thanks

Before issueing a MAM or MAJ command, check that the .InhibitStatus bit is OFF and the .ServoActionStatus bit is ON and the .DriveEnableStatus bit is ON.

AJZ,

Which instruction set bits the .ServoActionStatus bit is ON and the .DriveEnableStatus bit is ON?

Thanks

You have to turn the axis on using the Motion Servo On - MSO command to close to the servo loop and enable to the drive output. The counterpart is Motion Servo Off - MSF
