AUTOAUTO The drive starts the motor instantly from zero frequency ifparameter 9904 MOTOR CTRL MODE setting is SCALAR:FREQ. If flying start is required use selection SCAN START.If parameter 9904 MOTOR CTRL MODE value is VECTOR:SPEED or VECTOR: TORQ, the drive pre-magnetizes themotor with DC current before the start. The pre-magnetizingtime is defined by parameter 2103 DC MAGN TIME. Seeselection DC MAGN.For permanent magnet motors, flying start is used if themotor is rotating.1DC MAGN The drive pre-magnetizes the motor with DC current beforethe start. The pre-magnetizing time is defined by parameter2103 DC MAGN TIME.If parameter 9904 MOTOR CTRL MODE value is VECTOR:SPEED or VECTOR: TORQ, DC magnetizing guaranteesthe highest possible break-away torque when the pre-magnetizing is set long enough.Note: Starting the drive connected to a rotating motor is notpossible when DC MAGN is selected. When a permanentmagnet motor is used, alarm MOTOR BACK EMF (2029) isgenerated.WARNING! The drive will start after the set pre-magnetizing time has passed even if the motormagnetization is not completed. In applications where a fullbreak-away torque is essential, always ensure that theconstant magnetizing time is long enough to allowgeneration of full magnetization and torque.2All parametersNo. Name/Value Description Def/FbEq
