If thecommand speed matches the motor speed, little if any motor disturbance is seenduring restarting. This is useful when restarting a single motor on a movingprocess line.This method does have the disadvantage that the motor torque disturbance duringresynchronization may be unacceptable to some applications, since the motorattempts to accelerate to the commanded speed at the current limit setting of thecontroller.NmNspVmImLI110LI2 1 0Nm - Motor SpeedNsp - CommandedSpeedVm - Motor VoltageIm - Motor CurrentLI1 - Run EnableLI2 - Run ForwardGreen OnPwrLEDOffPowerOffPowerOnFigure 65: Catch On Fly Set to ILIMITMotor OverloadWARNINGMOTOR OVERHEATINGThis drive controller does not provide direct thermal protection for the motor. Use of athermal sensor in the motor may be required for protection at all speeds or loadingconditions.

This function can replace a conventional class 10thermal overload relay for single motor applications; however, multi-motorapplications require individual external thermal overload motor protection.© 1996 Square D All Rights Reserved105ηττπ://νιχοντρολσ.χοm
