4.7.7 Status Word According to FC ProfileIllustration 4.30 Status WordThe status word is used to inform the master (e.g. a PC) ofthe slave's (frequency converter) mode. Slave⇒Master.Bit Bit=0 Bit=100 Control ready01 Drive ready02 Coasting stop03 No trip Trip04 Not used05 Not used06 Trip lock07 No warning Warning08 Speed≠ref. Speed=ref.09 Local control Ser. communi.10 Outsidefrequency rangeFrequency limitOK11 Motor running1213 Voltage warn.14 Current limit15 Thermal warn.Table 4.14 Status Word Bit DefinitionBit 00, Control readyBit 00='1'. The frequency converter is ready for operation.Bit 00='0'. The frequency converter is not ready foroperation.Bit 01, Drive readyBit 01='1'. The frequency converter is ready for operation,but there is an active coasting command via the digitalinputs or via serial communication.Bit 02, Coasting stopBit 02='0'. The frequency converter has released the motor.Bit 02='1'. The frequency converter can start the motorwhen a start command is given.Bit 03, No trip/tripBit 03='0' means that the frequency converter is not infault mode.Bit 03='1' means that the frequency converter is tripped,and that it needs a reset signal for operation to bereestablished.Bit 04, Not usedBit 04 is not used in the status word.Bit 05, Not usedBit 05 is not used in the status word.Bit 06, Trip lockBit 06='0' means that the frequency converter is not triplocked.Bit 06='1' means that the frequency converter is trip lockedand it cannot be reset before the mains supply has beenremoved. The trip can be reset either with 24 V externalcontrol back-up, or after the power is connected again.Bit 07, No warning/warningBit 07='0' means that there are no warnings.Bit 07='1' means that a warning has occurred.Bit 08, Speed≠ref/speed=ref.Bit 08='0' means that the motor is running, but that thepresent speed is different from the preset speed reference.It might, for example, be the case while the speed is beingramped up/down during start/stop.Bit 08='1' means that the motor's present speed is thesame as the preset speed reference.Bit 09, Local operation/serial communication controlBit 09='0' means that [STOP/RESET] is activated on thecontrol unit, or that [1] Local control in parameter 002Local/remote operation is selected. It is not possible tocontrol the frequency converter via serial communication.Bit 09='1' means that it is possible to control the frequencyconverter via serial communication.Bit 10, Outside frequency rangeBit 10='0', if the output frequency has reached the value inparameter 201 Output frequency low limit or parameter 202Output frequency high limit.Bit 10="1", means that the output frequency is within thedefined limits.Bit 11, Running/not runningBit 11='0' means that the motor is not running.Bit 11='1' means that the frequency converter has a startsignal or that the output frequency is greater than 0 Hz.Bit 13, Voltage warning high/lowBit 13='0' means that there are no voltage warnings.Bit 13='1' means that the DC voltage in the frequencyconverter's intermediate circuit is too low or too high.Bit 14, Current limitBit 14='0' means that the output current is less than thevalue in parameter 221 Current Limit ILIM.Bit 14='1' means that the output current is greater thanthe value in parameter 221 Current LimitILIM and that thefrequency converter trips after a set period of time.Bit 15, Thermal warningBit 15='0' means that there is no thermal warning.Bit 15='1' means that the temperature limit has beenexceeded in either the motor, frequency converter or froma thermistor that is connected to a digital input.Programming Design Guide112 Danfoss A/S © Rev.
