Goodrive350-19 Series VFD for Crane
LSB of data writing address
MSB of data content
LSB of data content
Note: The sections 10.4.1 Command code 03H, reading N words (continuously up to 16 words)
and 10.4.2 Command code 06H, writing a word mainly describe the command formats. For the
detailed application, see the examples in section 10.4.7 Read/Write operation examples.
10.4.3 Command code 10H, continuous writing
The command code 10H is used by the master to write data to the VFD. The count of data to be
written is determined by "Data quantity", and a maximum of 16 pieces of data can be written.
For example, if the master writes 5000 (1388H) and 50 (0032H) to 0004H and 0005H of the VFD
whose address is 02H, the frame structure is as follows.
RTU master command (from the master to the VFD) is as follows:
MSB of data writing address
LSB of data writing address
Data count MSB
Data count LSB
Number of bytes
MSB of data 0004H content
LSB of data 0004H content
MSB of data 0005H content
LSB of data 0005H content
RTU slave response (from the VFD to the master) is as follows:
MSB of data writing address
LSB of data writing address
