Fault Message Response - INVT Goodrive20-EU VFD Series Operation Manual

Goodrive20-EU series VFD
Because the parameter data is 0032H (50) and 50 divided by 10 is 5, then the hibernation
restore delay time is 5s.

7.4.4 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 VFD will return a fault response message.
The fault message is from the VFD to the master, its code and meaning is as follows:
Code
01H Illegal command
02H Illegal data address.
03H Illegal value
04H Operation failed
05H Password error
06H Data frame error
07H Written not allowed.
The parameter cannot
08H be modified during

address command
Name
The command from master cannot be executed. The
reason maybe:
1. This command is only for new version and this version
cannot realize.
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 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
cannot be modified during running.
