Functions
<Writing into the holding register [06h]>
Writes data into the specified holding register.
(Example)
Write "50 Hz" into the Inverter with slave address "8" as multi-step speed reference 0 (A020).
The data resolution of the holding register "1029h" of multi-step speed reference 0 (A020) is 0.1 Hz.
To set 50 Hz, set the change data to "500 (01F4h)".
*1. There is no response for broadcasting.
*2. Note that the holding register start address is "1028h", which is smaller by 1 than the register
number "1029h".
Refer to "<Exception Response>" (4-75) if writing into the holding register cannot be performed nor-
mally.
<Loopback Test [08h]>
Used to check the communications between master and slave. A random value can be used for test
data.
(Example)
Loopback test to the Inverter with the slave address "1"
* Broadcasting cannot be performed.
The test sub code corresponds only with the query data echo (00h, 00h), not any other command.
