RS485 port can use to control multiple inverter by connect the signal in parallel.
l
The option of RS485/232 card is used to convert RS485 into RS232.
l
The option of standard cable (CABLE_RS485) is used to transform JAM connector (CON6) into standard 9 pin D-
sub Male connector. The definition the D-sub connector is:
9 pin D-sub Male Connector

。
15.3 JPS Protocol & Format
All code transfer between Computer and Drive are ASCII code, and the “CR” code (0x0D) must add to the end of each
command string.
Data Format: 7 Bit data
,
Even Parity
。
15.3.1 Computer to Inverter
Computer may send three types of message to drive.
15.3.1.1
Control Command (No response will send back from drive)
Format: “C,uu,cc,fffff”
C
:
Head of COMMAND String.
uu
:
ID of drive, from 00 to 99.
If the “uu” code in command string is “00”, all drives can be controlled at the same time.
cc
:
Control command code, from 00 to 15.
The “cc” number is actually converted from four bits binary data.
cc= 8 * Bit-3 (JOG) + 4 * Bit-2 (Reverse) + 2 * Bit-1 (RUN) + Bit-0 (Reset)
Control Code
Function
cc=00
Stop
cc=01
Reset
cc=02
Forward Run
cc=06
Reverse Run
cc=10
Forward JOG Run
cc=14
Reverse JOG Run
fffff
:
Set Frequency.
PDAN/PDA/PDE series: from 00000 to 65000, representing desired
Hz = 0.00 to 650.00
PDH series: from 00000 to 30000, representing desired
Hz = 0.0 to 3000.0
15.3.1.2 Write Command (No response will send back from drive)
format: “W,uu,nn,ddddd” or “W,uu,nnn,ddddd”
W
:
Head of WRITE String.
uu
:
ID of drive, from 00 to 99.
If the “uu” code in command string is “00”, all drives can be controlled at the same time.
nn(n)
:
PDAN series: If Protocol P=0, Parameter format is “nn”, from 00 to 99
If Protocol P=1, Parameter format is “nnn”, from 000 to 999
PDA/PDE/PDH series: Parameter format is “nn”, from 00 to 99
ddddd
: data value, from 00000 to 65535.
If data exceed upper or lower limit (shown in parameter table) will be trimmed within
boundary automatically.
15.3.1.3 Read Command (Drive will send back P-string after receive this string)
Format: “R,uu,nn” or “R,uu,nnn”
R
:
Head of READ String
uu
:
ID of drive, from 01 to 99.
Do not specify uu=00 for Read Command while multiple drives are under control.
nn(n)
:
PDAN series: If Protocol P=0, Parameter format is “nn”, from 00 to 99
If Protocol P=1, Parameter format is “nnn”, from 000 to 999
PDA/PDE/PDH series: Parameter format is “nn”, from 00 to 99
