S611 Soft Starter MN03902011E—May 2012 www.eaton.com 51S611 Motor Protection ParametersThe S611 implements the following protection features. Each protection feature is individuallyconfigured and enabled by the user. Some of the features are designed to protect the motorand others are for internal protection of the S611.Motor ParametersOne or more of the motor protection features need the following motor parameters. The usermust input these values prior to enabling protection.Motor Parameters Required for ProtectionInstantaneous OvercurrentWhen the bypass contactors are not engaged, the S611 monitors the maximum rms valueof the three-phase currents. The unit will trip with an instantaneous overcurrent fault if themaximum value exceeds six times the catalog FLA setting for 1.5 seconds. This internalprotection mechanism is most useful for protecting the S611 from starting a motor too largefor its ratings.Instantaneous Overcurrent SettingsMotor StallThe S611 monitors the maximum rms value of the three-phase currents. The unit will trip witha motor stall fault if the stall fault is enabled and the maximum rms value exceeds the tripthreshold setting when the start time setting expires.Motor Stall SettingsParameter Set Point Range Step Default NotesMotor rated voltage 130–600 1 480 Settable from the UIMode O/P LEDOperation Motor rated voltageMotor FLA 26–414(depends on unit ID)FLA <100, 0.1AFLA >=100, 1ADepends on unit ID Settable from the UIMode O/P LEDOperation Motor FLATrip class Off, 5–30 1 20 Settable from the UIMode O/P LEDProtection Trip classPhase sequence 0 = Don’t care1 = ABC2 = ACBN/A 1 = ABC Settable from UIMode O/P LEDProtection Phase sequenceParameter Set Point Range Step Default NotesTrip threshold 600% of catalog FLA N/A N/A Not user settableTrip delay 1.5 seconds N/A N/A Not user settableParameter Set Point Range Step Default NotesTrip threshold OFF, 150–300% ofFLA setting1% 200% Settable from the UIMode O/P LEDProtection Stall trip %Trip delay N/A N/A N/A Instantaneous rms value at end-of-ramp is usedwww.comoso.com
