<No Response>
The Inverter ignores a query and does not respond when:
•The broadcast is received.
•A communication error is detected in receiving a query.
•The query slave address does not correspond with the slave address set for the Inverter.
•The time interval between 2 pieces of data constituting the message is less than a 3.5-character
length.
•Query data length is inappropriate.
•The reception interval in a frame exceeds the 1.5-character length.
Note: Provide a timer in the master to monitor the response, and if no response is returned within
the set time period, send the same query again.
Explanation of Each Function Code
<Coil status reading [01h]>
Reads out the coil status (ON/OFF).
(Example)
When reading multi-function input terminals from 1 to 5 of the Inverter with the slave address "8"
Refer to the following table for multi-function input terminal statuses. (Coils from 12 to 14 are OFF.)
*1. Broadcasting cannot be performed.
*2. When specifying the value for 0 or over 31 of the reading coils, the error code "03h" is sent.
*3. Data is transferred by the number of data bytes.
The data received as the response shows the statuses of coils 7 to 14. The data received here, "05h
= 00000101b", should be read with setting coil 7 as LSB as follows:
If the reading coil exceeds the defined coil range in the final coil data, such coil data is regarded as
"0" and returned.
