Device part of <Figure 1> input Com Port(COM1), Baud Rate(19200), Parity Bit(2), Data Bit(8), Stop Bit(2) respectively according to setting of controller.
Baud rate(4800, 600, 1200, 2400,4800, 9600, 19200), parity bit(0, 1, 2), stop bit(1, 2) can set by using 'setting button' of FREQROL 500 Series.
Also you can input 'enable of Link Parameter Expansion's auto setting' (1 : enable, 0 : disable, default = 1), 'type of communication end code'(0 : none, 1 : CR, 2 : CR+LF, default = 1), 'use of Waiting Time in Protocol'(1 : use, 0 : don't use : 0, default = 1), 'Waiting Time when using Waiting Time'(0 ~ 15, unit = 10ms, default = 1), 'send of ACK packet after reading'(1 : send, 0 : don't send : 0, default = 0) by using option part.
Note) When Instruction number of 30(Extended function display selection) = 0(break - MRS type) , the usable Instruction number are 0 ~ 9, 30, 79 ...
Note) Please refer to 4 chapter for setting of controller's station number, baud rate, etc.
FREQROL 500 Series Inverter communication driver read schedule
Read schedule setting parameters are as follows:
1) STATION – Controller's station number = 0 ~ 31.
2) Link Parameter Expansion – Expansion number = 0 ~ 9. ( Refer to <Table 1> or reference manual of FREQROL 500 Series Inverter )
3) Instruction number – Read Instruction number = 0 ~ 127. ( Refer to <Table 1> or reference manual of FREQROL 500 Series Inverter )
4) Save Start Address for Communication Server – saveing start address of Communication Server.
5) Read Size – read word size = fixed to 1.

Please refer to reference manual of FREQROL 500 Series Inverter for readed data value and contents.
If you click the icon 
in protocol option part, you
can see the dialogue box such as <Figure 2>. you can also set read schedule by
using this part.

You can set read schedule by using 
, 
, 
button and listbox of <Figure
2>.
Also you can set enable of Link Parameter Expansion's auto setting, type of communication end code, use of Waiting Time in Protocol, Waiting Time, send of ACK packet after reading at the part of ¡®Communication Option¡¯ shown in <Figure 2>.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.
You can write setting value of inverter by using write settings.
Digital Write
Digital write and Analog write have the same setting parameters except output value(0 or 1).
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Controller station number = 1 ~ 31.
3) ADDRESS Write Instruction number = 0 ~ 127( or 128 ~ 255, decimal unit). ( Refer to <Table 1> or reference manual of FREQROL 500 Series Inverter )
4) Extra1 Expansion number = 0 ~ 9. ( Refer to <Table 1> or reference manual of FREQROL 500 Series Inverter )
5) Extra2 Number of writing bytes.(default = 2)
1 : 1 byte data,
3 : 3 byte data,
2, space, ... : 2 byte data. (default)
Note) In order to write some Instruction number, you should be set 'EXT' mode of Inverter's communication mode.
Also when the 77 Instruction number's value equal 1 or 0 and PU operation mode equal don't stop, you can't set most of the parameter. (you can set 75, 77, 79, .. Instruction parameters)
But you can set parameter when the 77 Instruction number's value equal 2 regardless of PU mode.
Write example 1)
PORT:0, station:0, ADDRESS:0001, Extra1: 0, Extra2 :
The setting parameter shown above is maximum frequency setting example of 0 station FREQROL 500 Series Inverter.
Write example 2)
PORT:0, station:0, ADDRESS:0002, Extra1: 0, Extra2 :
The setting parameter shown above is minimum frequency setting example of 0 station FREQROL 500 Series Inverter.
Connection of communication cable and main power are as follows.
Connection of communication cable
Please connect RS-485 communication cable to RS-485 connector of FREQROL 500 Series Inverter such as <Figure 4>.
