D.2.3 8WORD communication protocol meaning, this type includes 8 control
words and 8 status words:
D.2.3.1 Inverter control word
Control word WORD1, specific definition of each bit is as follows:
15 8 7 0
bit0: Off1 switch command: 0 indicates stopping, 1 indicates starting
bit1: Off2 base blocking: 0: PWM blocking, output contactor disconnected, holding brake closed; 1 normal running
bit2: quick stop command. 0: quick stop, decelerate and stop according to the deceleration time of the setting of P40.09. 1: normal
running
bit3: x reserved
bit4: x reserved
bit5: x reserved
bit6: Master/slave control 0: Speed control; 1: Torque control (only valid with AS600 series)
bit7: 0->1 Hop clear current fault
bit8: x reserved
bit9: x reserved
bit10: 0: PLC command invalid; 1: PLC command valid
bit11: Motor parameter group switching 0: First group; 1: Second group
bit12: x reserved
bit13: x reserved
bit14: x reserved
bit15: x reserved
Bit12: Switching speed loop integral adjustment
Control word WORD2: speed preset, for example: 5000 indicates forward rotation at 50.00 Hz;
-5000 indicates reverse rotation at 50.00 Hz
Control word WORD3: torque preset (0.1%), with symbol, standard value motor rated torque, 999
indicates 99.9%, -1000 indicates -100.0% (only valid in the slave mode (torque mode) of the AS600
series)
Control word WORD4: Compensating torque preset (0.1%), with symbol, standard value motor
rated torque, 999 indicates 99.9%, -1000 indicates -100.0% (only valid in the master mode (speed
mode) of the AS600 series)
Control word WORD5: VF separation voltage preset (0.1%)
Control word WORD6: PLC forced DO output, high 8 bits enable output, and low 8 bits are output
values
Control word WORD7: Acceleration (* *. * * s), 10000 indicates 10.00s. This sets the time
accelerated from 0 to rated frequency.
Control word WORD8: Deceleration (* *. * * s), 10000 indicates 10.00s. This sets the time
decelerated from rated frequency to 0.
