D.2.1.2 Inverter status word
Status word WORD1, specific definition of each bit is as follows:
15 8 7 0
Bit0: 0: Prohibit enabling PW/M; 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 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 means forward rotation at 50.00 HZ; -5000 means
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
