9.3.4 Power Up Mode
Parameter P-14 (PM) sets the power up mode for the drive.
8: Modbus/RTU
9: Q mode with Modbus/RTU communication, stored Q program auto-executes at power-up.
9.3.5 Modbus/RTU Data Framing
Modbus/RTU is a master and slave communication system. The CRC checking code includes from drive’s address bits to data bits.
This standard data framing is as follows:
Address
Function
Data
CRC
Based on data transfer status, there can be two types of response codes:
Normal Modbus response:
response function code = request function code
Modbus error response:
response function code = request function code + 0x80 (providing an error code)
