Fault Message Response - INVT Goodrive 310-UL Series Operation Manual

GD310-UL series VFD
After the VFD receives the command, it will change 50 into 5 according to the fieldbus ratio value and
then set the hibernation restore delay time as 5s.
Another example, after the upper monitor sends the command of reading the parameter of
hibernation restore delay time, if the response message of the VFD is as following:
Because the parameter data is 0032H (50) and 50 divided by 10 is 5, then the hibernation restore
delay time is 5s.

10.4.7 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 below:
Code Name
Illegal command
01H
Illegal data
02H
address
03H Illegal value
04H Operation failed
05H Password error
06H Data frame error
Parameters only
07H
for read
Parameters
cannot be
08H
changed during
running
Password
09H

VFD
2-byte
command
address
The command from master cannot be executed. The reason maybe:
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 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 modified parameter in the writing of the upper monitor cannot 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.
