Because the parameter data is 0032H (50) and 50 divided by 10 is 5, then the hibernation restore delay time is 5s.
7.3.6 Fault message response
There may be fault in the communication control. For example, some parameter can only be read. If a writing
message is sent, the inverter will return a fault response message.
The fault message is from the inverter to the master, its code and meaning is as below:
Code Name
01H Illegal command
Illegal data
02H
address
03H Illegal value
04H Operation failed
05H Password error
06H Data frame error
Written not
07H
allowed
The parameter can
08H not be changed
during running
Password
09H
protection
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:
Communication protocol
The command from master can not be executed. The reason maybe:
1. This command is only for new version and this version can not realize.
2. Slave is in fault state and can not 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 can not 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 monitor, the length of the digital frame is
incorrect or the counting of CRC check bit in RTU is different from the lower monitor.
It only happen in write command, the reason maybe:
1. The written data exceeds the parameter range.
2. The parameter should not be modified now.
3. The terminal has already been used.
The modified parameter in the writing of the upper monitor can not be
modified during running.
When the upper monitor is writing or reading and the user password is
set without password unlocking, it will report that the system is locked.
