Error Messages - INVT Goodrive18 Series Operation Manual

Goodrive18 series two-in-one VFD
(5.0=50/10).
To set "Delay for recovery from hibernation" to 5.0s through Modbus communication, you need
first to multiply 5.0 by 10 according to the scale to obtain an integer 50, that is, 32H in the
hexadecimal form, and then send the following write command:
After receiving the command, the VFD converts 50 into 5.0 based on the fieldbus scale, and
then sets "Delay for recovery from hibernation" to 5.0s.
For another example, after the upper computer sends the " Delay for recovery from
hibernation" parameter read command, the master receives the following response from the
VFD:
The parameter data is 0032H, that is, 50, so 5.0 is obtained based on the fieldbus scale
(50/10=5.0). In this case, the master identifies that the "Delay for recovery from hibernation" is
5.0s.

7.4.4 Error messages

Operation errors may occur during communication-based control. For example, some
parameters are read only, but a write command is sent. In this case, the VFD returns an error
message. Error messages are sent from the VFD to the master. The following table lists the
error messages.
