7. Connecting inverter with host controller
(1) Operation procedure
A. Turn on the inverter, set the related parameters and turn off the inverter.
B. Turn on the inverter again.
C. Connect inverter and host controller.
D. Host controller sends communication message.
(2) Communication status indication of inverter
While Run/Stop command and/or Frequency reference is from RS-485 (Sn-08), and the
inverter does not receive any message from host controller after power on 1 seconds,
the inverter will display "Call" and flash. This message will disappear while inverter has
received messages from host controller.
While Run/Stop command and/or Frequency reference is from RS-485 (Sn-08), the
time-out detection is enabled (Cn-31 <> 0) and the inverter does not receive any
message from host controller in time specified by Cn-31, the inverter will display
"CPF21".
While Run/Stop command and/or Frequency reference is from RS-485 (Sn-08), the
inverter receives any message with incorrect communication format. (Baud rate, parity,
data bit and stop bit) the inverter will display "CPF22".
Bit 2, 3 of parameter Sn-08 will decide the display format and operation of “CPF21",
“CPF22".

8. Protocol Format
(1) A message of MODBUS RTU mode contains 4 parts: slave address, function code,
data and CRC-16 character. The interval between two messages needs 3.5
characters transferring time.
T1 T2 T3 T4
T1~T4 : 3.5 Characters transferring time at least
(2) Following is the data bit format for MODBUS RTU mode. (LSB will be sent first)
Even/Odd Parity Start 1 2 3 4 5 6 7 8 Parity Stop
No Parity Start 1 2 3 4 5 6 7 8 Stop Stop
(3) Slave Address
Parameter Sn-23 can set the node address of each inverter (1~31). Every slave stand
can receive the message sent from host controller. Only the corresponding one returns
the message to master.
If the slave address of receiving message is 0, all slave stands will execute this

(6) CRC-16 data
CRC-16 Generation Procedure.
A. Load a 16-bit register with FFFFH. Call this the CRC register.
B. Exclusive OR the first 8-bit byte of the message with the low order byte of the 16-bit
CRC registers, putting the result in the CRC register.
C. Shift the CRC register one bit to the right (toward the LSB), zero filling the MSB.
Extract and examine the LSB.
D.If LSB is 0, repeat procedure C (another shift).
If LSB is 1, Exclusive OR the CRC register with the polynomial value A001H.
E. Repeat procedure C, D until eight shifts has been performed.
While this is done, a complete byte will have been processed.
F. Repeat procedure B-E to the following byte of the message until all bytes of the
message is processed.
Now, the value of CRC register is the CRC-16 data.
G. When the CRC is placed into the message, it upper and lower bytes must be
swapped.
(7) Inverter return messages
A. Please refer to the “Message Format” in next page about inverter returning
messages for more detail descriptions.
B. It needs 5ms to return messages after inverter had received normal message from
host controller.
C. In next two cases, inverter does not return any message :
(a) There is any error detected in received data message (parity error, framing error,
overrun error or CRC-16 error).
(b) Slave Address character is different to parameter Sn-36 (Inverter Slave No.).

(1) Run 7300PA forward with 60Hz. Set DO1-DCOM.
(2) Run 7300PA forward with 30Hz. Clear DO1-DCOM. Set R1A-R1C.
(3) Run 7300PA reverse with 30Hz. Set R1A-R1C.
(4) Stop 7300PA. Set R1A-R1C.

(1) Set inverter parameters
Sn-23 = 1 (Inverter Slave Address), Sn-24
Cn-31 = 0.0s (Disable time-out check)
Sn-08 = 1100
--
(11

00 : Run/Stop and frequency reference from RS-485)
Sn-21 = 0F (DO1-DCOM Output Reserved), Sn-22 = 0F (R1A-R1C Output Reserved)
(2) Turn off the inverter and turn it on again (For Sn-23 and Sn-24 are modified). and
program host controller to operate in step 1-4 and desired operation can be done by
inverter.
