To re-establishoperation, enter [Reset].Bit 04, No error/error (no trip)Bit 04=’0’: The frequency converter is not in fault mode.Bit 04=“1”: The frequency converter shows an error butdoes not trip.Bit 05, Not usedBit 05 is not used in the status word.Bit 06, No error/triplockBit 06=’0’: The frequency converter is not in fault mode.Bit 06=“1”: The frequency converter is tripped and locked.Bit 07, No warning/warningBit 07=’0’: There are no warnings.Bit 07=’1’: A warning has occurred.Bit 08, Speed≠ reference/speed=referenceBit 08=’0’: The motor is running but the present speed isdifferent from the preset speed reference. It could be thecase when the speed ramps up/down during start/stop.Bit 08=’1’: The motor speed matches the preset speedreference.Bit 09, Local operation/bus controlBit 09=’0’: [Stop/Reset] is activated on the control unit orLocal control in 3-13 Reference Site is selected. Thefrequency converter cannot be controlled via serialcommunication.Bit 09=’1’ It is possible to control the frequency convertervia the fieldbus/serial communication.Bit 10, Out of frequency limitBit 10=’0’: The output frequency has reached the value in4-11 Motor Speed Low Limit [RPM] or 4-13 Motor Speed HighLimit [RPM].Bit 10="1": The output frequency is within the definedlimits.Bit 11, No operation/in operationBit 11=’0’: The motor is not running.Bit 11=’1’: The frequency converter has a start signal or theoutput frequency is greater than 0 Hz.Bit 12, Drive OK/stopped, autostartBit 12=’0’: There is no temporary over temperature on theinverter.Bit 12=’1’: The inverter stops because of over temperaturebut the unit does not trip and resumes operation once theover temperature stops.Bit 13, Voltage OK/limit exceededBit 13=’0’: There are no voltage warnings.Bit 13=’1’: The DC voltage in the intermediate circuit is toolow or too high.Bit 14, Torque OK/limit exceededBit 14=’0’: The motor current is lower than the torque limitselected in 4-18 Current Limit.Bit 14=’1’: The torque limit in 4-18 Current Limit isexceeded.Bit 15, Timer OK/limit exceededBit 15=’0’: The timers for motor thermal protection andthermal protection are not exceeded 100%.Bit 15=’1’: One of the timers exceeds 100%.If the connection between the Interbus option and thefrequency converter is lost, or an internal communicationproblem has occurred, all bits in the STW are set to ’0.'RS-485 Installation and Set...
