Mitsubishi FR-A800

(N) Operation via communication and its settings
584
PARAMETERS
Preset Single Register (writing of data to holding registers) (H06 or 06)
• The content of the "system environmental variables" and "inverter parameters" assigned to the holding register area (refer
to the register list (page 589)) can be written.
• Query message
• Normal response (Response message)
• Query message setting
• Content of normal response
With a normal response, the content is the same as a to d (including the CRC check) query messages.
In the case of broadcast communication, no response is returned.
NOTE
• With broadcast communication, no response is generated even if a query is executed, so when the next query is made, it
must be made after waiting for the inverter data processing time after the previous query is executed.

Message Description
a Slave Address Set the address to send messages to. Setting "0" enables broadcast communication.
b Function Set H06.
c Register Address
Set the address from data is written to the holding register.
Register address = holding register address (decimal) - 40001
For example, when register address 0001 is set, data is written to holding register
address 40002.
d Preset Data Set the data to write to the holding register. Write data is fixed at 2 bytes.
Example) Write 60Hz (H1770) to 40014 (running frequency) of slave address 5 (H05).
