Chapter 5—System Configuration and OperationPower Xpert C445 Global Motor Management Relay MN042003EN—October 2016 www.eaton.com 93Control SettingsThe following parameters are used to configure the Two SpeedDahlander Operation Mode and the C445 sources of control.Table 19. Two Speed Dahlander Configuration ParametersNote1 Soft reset (power cycle) required for changes to these parameters to take effect.Fieldbus Control WordThe two speed Dahlander motor starter profile will acceptthe following control commands over a fieldbus network.Control BitsBit 0/1 00 = Stop command, de-activate all control outputs01 = Run Slow command, activate Output 110 = Run Fast command, activate Outputs 2 & 311 = Unknown command, No actionBit 3 0 = No action1= Reset fault (will clear fault provided conditionhas cleared)Bit 5 0 = No action1= The C445 will issue a “Test Trip” fault causingthe Outputs 1-3 control relays to open.Control Status WordThe control status word of the two speed Dahlander motorstarter profile can be accessed over the fieldbus network.Status BitsBit 0/1 00 = Stopped (No active Run commands)01= Running1 (Run Slow command is active)10= Running2 (Run Fast command is active)Bit 2 0 = local control source active1= remote control source is activeBit 3 0 = no fault present1= C445 fault presentBit 4 0 = no warning present1= C445 warning presentBit 5 0 = no inhibit present1= C445 control inhibit presentBit 6 0 = C445 not ready (fault and/or inhibit present)1= C445 ready for control (No fault or inhibit present)Bit 7 0 = motor is not up to speed (AtRef)1= C445 has detected motor is up to speed (AtRef)Two conditions will set the AtRef bit, signaling the motor isup to speed.● If motor current first exceeds 115% of the active overloadFLA rating and then decreases back below 115% of theactive overload FLA rating, it is determined the motor hascome up to speed and the AtRef bit will be set.● If motor current exceeds 30% of the active overload FLArating and remains until after the start delay time expiresthe motor is determined to be up to speed and the AtRefbit will be set.Configuration Parameter Modbus Register Description Read/WriteActive Operation Mode 1 700 This parameter selects the Operation Mode R/WControl Fault Delay 701 Delay time before a control fault is issued.
