Jps Protocol & Format - JPS PDA Series Instruction Manual

l 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
PIN1~3
PIN4
PIN5
PIN6
PIN7~9
Note: PDA/PDE/PDH series must use RS485/232 option card when using serial communication control。
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:
uu:
cc:
fffff:
15.3.1.2 Write Command (No response will send back from drive)
format: "W,uu,nn,ddddd" or "W,uu,nnn,ddddd"
W:
uu:
nn(n) :
ddddd
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:
uu:
nn(n) :
Definition
N.C.
A (SIG+)
B (SIG-)
0V
N.C.
Head of COMMAND String.
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.
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
cc=00
cc=01
cc=02
cc=06
cc=10
cc=14
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
Head of WRITE String.
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.
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
: data value, from 00000 to 65535.
If data exceed upper or lower limit (shown in parameter table) will be trimmed within
boundary automatically.
Head of READ String
ID of drive, from 01 to 99.
Do not specify uu=00 for Read Command while multiple drives are under control.
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
