INVT Goodrive200A Series User Manual

GD200A series VFD Communication protocol
-143-
hibernation restore delay time, if the response message of the VFD is as following:
VFD
address
Read
command
Parameters
data
CRC check 2-byte
data
Because the parameter data is 0032H (50) and 50 divided by 10 is 5, then the hibernation restore
delay time is 5s.
9.5.4 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
Name
Meaning
01H
Illegal command
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.
02H
Illegal data
address.
Some of the operation addresses are invalid or not allowed to access.
Especially the combination of the register and the transmitting bytes
are invalid.
03H
Illegal value
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.
04H
Operation failed
The parameter setting in parameter writing is invalid. For example, the
function input terminal cannot be set repeatedly.
05H
Password error
The password written to the password check address is not same as
the password set by P07.00.
06H
Data frame error
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.
07H
Written not
allowed.
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.
08H
The parameter
cannot be
changed during
running
The modified parameter in the writing of the upper monitor cannot be
modified during running.
09H
Password
protection
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.
