Goodrive350-19 Series VFD for Crane
01
address
After receiving the command, the VFD converts 50 into 5.0 based on the fieldbus scale, and then sets
"Wake-up-from-sleep delay" to 5.0s.
For another example, after the upper computer sends the "Wake-up-from-sleep delay" parameter
read command, the master receives the following response from the VFD:
01
address
The parameter data is 0032H, that is, 50, and therefore 5.0 is obtained based on the fieldbus scale
(50/10=5.0). In this case, the master identifies that "Wake-up-from-sleep delay" is 5.0s.
10.4.6 Error message response
Operation errors may occur in communication-based control. For example, some parameters can
only be read, but a write command is sent. In this case, the VFD returns an error message response.
Error message responses are sent from the VFD to the master. The following table lists the codes and
definitions of the error message responses.

command
The command code received by the upper computer is not allowed to be
executed. The possible causes are as follows:
The function code is applicable only on new devices and is not
implemented on this device.
The slave is in the faulty state when processing this request.
For the VFD, the data address in the request of the upper computer is not
allowed. In particular, the combination of the register address and the
number of the to-be-sent bytes is invalid.
The received data domain contains a value that is not allowed. The value
indicates the error of the remaining structure in the combined request.
Note: It does not mean that the data item submitted for storage in the
register includes a value unexpected by the program.
The parameter setting is invalid in the write operation. For example, a
function input terminal cannot be set repeatedly.
The password entered in the password verification address is different from
that is specified by P07.00.
The data frame sent from the upper computer is incorrect in the length, or in
the RTU format, the value of the CRC check bit is inconsistent with the CRC
value calculated by the lower computer.
