Moog MSD Servo Drive Series User Manual

CAUTION! Damage to the device as a result of incorrect operation!
Failure to exercise caution or follow proper working
procedures may result in damage to the device.
 Themotorcanmovesuddenlyduringtheauto
commutation.Themechanismcoupledmustbe
designedforthismovement.

Ifthecommutationpositionisnotdeterminedcorrectly,
themotorwillaccelerateinanuncontrolledmanner.
This can lead todamagetothemechanicalsystem.

Makesuretocarefullytesttheautocommutation
function.Varythestartposition.Even if
autocommutation has not been performed, the drive
can be “made to rotate” in up to 50 % of cases.

Enable speed tracking error monitoring (P 744[0] -
SDiffMax, Section "Speed- / velocity limits" on page
253. This monitoring function provides extensive
protection against uncontrolled movement.
