6-1-4 Address list
1. ASCII
(1) Read one or multiple parameters: 3Ah (start word ‘:’ ) + 30h 31h (station 01) + 30h 33h
(function code 03h) + 30h 30h xxh xxh – 32h 36h xxh xxh (Modbus address 00xxh–26xxh) +
xxh xxh xxh xxh (read data length 1) + LRC (checksum) + CR/LF
(2) Write in one parameter: 3Ah (start word ‘:’ ) + 30h 31h (station 01) + 30h 36h (function code
06h) + 30h 30h xxh xxh – 32h 36h xxh xxh (Modbus address 00xxh–26xxh) + xxh xxh xxh xxh
(read data length 1) + LRC (checksum) + CR/LF
(3) Write in 20 parameters: 3Ah (start word ‘:’ ) + 30h 31h (station 01) + 31h 30h (function code
10h) + 30h 30h xxh xxh – 32h 36h xxh xxh (Modbus address 00xxh–26xxh) + 30h 30h 31h
34h (word data length) + 30h 30h 32h 38h (byte data length) + xxh xxh xxh xxh (the first write
in value) + ... + xxh xxh xxh xxh (the 20th write in value) + LRC (checksum) + CR/LF
2. RTU
(1) Read one or multiple parameters: 01h (station 01) + 03h (function code 03h) + 00xxh–26xxh
(Modbus address) + xxxxh (read data length) + CRC (checksum)
(2) Write in one parameter: 01h (station 01) + 06h (function code 06h) + 00xxh–26xxh (Modbus
address) + xxxxh (write in value) + CRC (checksum)
(3) Write in 20 parameters: 01h (station 01) + 10h (function code 10h) + 00xxh–26xxh (Modbus
address) + 0014h (word data length) + 0028h (byte data length) + xxxxh (the first write in
value) + xxxxh (the 20th write in value) + CRC (checksum)
3. Control command (20xx):
1: Once the drive receives one
command, it remains in the
operation status specified by
the command and will not
change the operation status
until it receives another new
command.
2: The function is only valid when
the operation command
source is set as
communication (Pr. A1-01 or
A1-08 = 8).
1: To enable this function, you
need to set 2000h bit12 as 1
first.
2: By reading 2367h, you can get
the currently executed step
speed.
