Goodrive300-19 series open loop vector inverter special for hosit Communication protocol
-224-
The command from master cannot be executed. The reason may
be:
1. This command is only for new device;
2. Slave is in fault state and cannot execute it.
Some of the operation addresses are invalid or not allowed to
access. Especially the combination of the register and the
transmitting bytes are invalid.
When there are invalid data in the message framed received by
slave.
Note: This error code does not indicate the data value to write
exceed the range, but indicate the message frame is an illegal
frame.
The parameter setting in parameter writing is invalid. For example,
the function input terminal cannot be set repeatedly.
The password written to the password check address is not same
as the password set by P7.00.
In the frame message sent by the upper computer, the length of the
digital frame is incorrect or the counting of CRC check bit in RTU is
different from the lower computer.
It only happens in write command
Parameters
cannot be
changed
during running
The modified parameter in the writing of the upper computer cannot
be modified during running.
When the upper computer is writing or reading and the user
password is set without password unlocking, it will report that the
system is locked.
The slave uses functional code fields and fault addresses to indicate it is a normal response or some
error occurs (named as objection response). For normal responses, the slave shows corresponding
function codes, digital address or sub-function codes as the response. For objection responses, the
slave returns a code which equals the normal code, but the first byte is logic 1.
For example: when the master sends a message to the slave, requiring it to read a group of address
data of the inverter function codes, there will be following function codes:
