Command Code 10H, Continuous Writing - INVT Goodrive350 Series Operation Manual

Goodrive350 series high-performance multifunction VFD
Sub-function code
For example, to query about the circuit detection information about the VFD whose address is 01H,
the query and return strings are the same, and the format is described in the following tables.
RTU master command:
MSB of the sub-function code
LSB of the sub-function code
MSB of data
LSB of data
LSB of CRC CHK
MSB of CRC CHK
RTU slave response:
MSB of the sub-function code
LSB of the sub-function code
MSB of data
LSB of data
LSB of CRC CHK
MSB of CRC CHK

9.4.4 Command code 10H, continuous writing

The command code 10H is used by the master to write data to the VFD. The quantity of data to be
written is determined by "Data quantity", and a maximum of 16 pieces of data can be written.
For example, to write 5000 (1388H) and 50 (0032H) respectively to 0004H and 0005H of the VFD
whose slave address is 02H, the structure of the frame is described in the following table.
RTU master command (transmitted by the master to the VFD):
MSB of data writing address
LSB of data writing address
MSB of data quantity
