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 might, forexample, be the case when the speed ramps up/downduring 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. Control viaserial communication is not possible.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 defined limits.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 overtemperature on theinverter.Bit 12=1: The inverter stops because of overtemperature,but the unit does not trip and resumes operation once theovertemperature stops.Bit 13, Voltage OK/limit exceededBit 13=0: There are no voltage warnings.Bit 13=1: The DC-voltage in the frequency converter’sintermediate circuit is too low 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 is exceeded.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%.All bits in the STW are set to 0 if the connection betweenthe interbus option and the frequency converter is lost, oran internal communication problem has occurred.3.8.12.3 Bus Speed Reference ValueSpeed reference value is transmitted to the frequencyconverter in a relative value in %. The value is transmittedin the form of a 16-bit word; in integers (0–32767) thevalue 16384 (4000 hex) corresponds to 100%. Negativefigures are formatted by means of 2’s complement. Theactual output frequency (MAV) is scaled in the same wayas the bus reference.Actual outputfreq.STWFollower-masterSpeed ref.CTWMaster-follower16bit130BA276.11Illustration 3.57 Actual Output Frequency (MAV)The reference and MAV are scaled as follows:Reverse ForwardPar.3-00 set to(1) -max- +maxMax reference Max referencePar.3-00 set to(0) min-maxMax referenceForwardMin reference100%(4000hex)-100%(C000hex)0%(0hex)Par.3-03 0 Par.3-03Par.3-03(4000hex)(0hex)0% 100%Par.3-02130BA277.10Illustration 3.58 Reference and MAVSystem Integration Design Guide90 Danfoss A/S © 09/2014 All rights reserved.
