Special control command word
Bit0–1: =00: motor 1 =01: motor 2
=10: motor 3 =11: motor 4
Bit2: =1 torque control =0: speed control
Virtual input terminal command , range:
0x000–0x1FF
Virtual output terminal command , range:

Voltage setting value(special for V/F
separation)
(0–1000, 1000 corresponds to the 100.0% of
the rated voltage of the motor)
AO output setting 1 (-1000–1000, 1000
corresponds to 100.0%)
AO output setting 2(-1000–1000, 1000
corresponds to 100.0%)
Bit0: =0: bus voltage is not established =1:
bus voltage is established
Bi1–2: =00: motor 1 =01: motor 2
=10: motor 3 =11: motor 4
Bit3: =0: asynchronous motor =1:
synchronous motor
Bit4: =0: pre-alarm without overload =1:
overload pre-alarm
Bit5– Bit6: =00: keypad control
=01: terminal control
=10: communication control
