7.5 Communication Control Parameter Group Address Description
ACH200 series function parameter address representation rules.
The address of the register is the function parameter serial number of the AC drive, which is
divided into two parts: high byte and low byte. The high byte indicates the group serial number
where the functional parameter is located, and the low byte indicates the group serial number of the
functional parameter, which needs to be converted to hexadecimal.
The high byte of the address field is defined as follows:
Parameter group code number Parameter address of this group
F0 Basic parameter group
0x00xx （ No deposit EEPROM ）
0x10xx （ Deposit EEPROM ）
F1 Operation control parameter
