D.2.3.2 Inverter status word
Status word WORD1, specific definition of each bit is as follows:
15 8 7 0
Bit0: 0: Prohibit enabling PWM; 1: Allow enabling PWM
Bit1: 0: Prohibit running; 1: Allow running
Bit2: 0: Stopping; 1: During operation, enabling PWM, with output current
Bit3: 0: Normal; 1: In fault
Bit4: 0: Select the first group of motor parameters; 1: Select the second group of motor parameters
Bit5: 0: Holding brake closed; 1: Holding brake output
Bit6: 0: PWM blocking; 1 normal
Bit7: 0: Normal; 1: Alarm
Bit8: 0: Not arriving the set frequency; 1: Arriving the set frequency
Bit9: 0: Status invalid; 1: Status valid
Bit10: 0: Main mode (speed mode); 1: Slave mode (torque mode)
Bit11: 0: Bus voltage normal; 1: Bus voltage too low
Bit12: 0: Bus voltage less than 85% of rated value; 1: Bus voltage not less than 85% of rated voltage
Bit13: 0: No forward rotation; 1: Forward rotation
Bit14: 0: No reverse rotation; 1: Reverse rotation
Note: meaning of the ninth bit (i.e. bit9) of the status word WORD1:
=0: Indicates that the inverter status received by PLC from PROFINET is invalid
=1: Indicates that the inverter status received by PLC from PROFINET is valid
Status word WORD2: Feedback frequency Hz, for example: 5000 indicates forward rotation at
50.00 Hz; - 5000 indicates reverse rotation at 50.00 Hz
In closed-loop control mode: this word represents the encoder feedback velocity
In V/F control mode: this word represents the actual output frequency
Status word WORD3: Output current A, for example: 100 indicates 10.0 A
Status word WORD4: Output voltage V, for example: 380 indicates 380 V
Status word WORD5: Custom status 1, set according to parameter P82.02
Status word WORD6: Custom status 2, set according to parameter P82.03
Status word WORD7: Custom status 3, set according to parameter P82.04
Status word WORD8: Custom status 4, set according to parameter P82.05
Attachment: Description of PROFINET custom status word
This description is mainly valid for the PROFINET 8WORD communication protocol type. The
last four words of the status word can be selected via the inverter parameters P82.02, P82.03, P82.04,
and P82.05. The selectable definitions for each parameter are as follows:
Parameter set to 0-7 standby
Parameter set to 8 reference torque of the inverter, signed, standard value for rated motor torque,
999 means 99.9%, -1000 means -100.0%
Parameter set to 9 standby
