APPENDIX B
Definition of Communication Parameter Addresses
Function parameters can be read and written (except those which cannot be
changed because they are only for the factory use or for monitoring).
Parameter group no. and parameter identifying no. are used to express parameter address.
High-order bytes: F0 to FF (groups F), A0 to AF (groups A), 70 to 7F (group U)
Low-order bytes: 00 to FF
For example, to read parameter F3-12, communication address of F3-12 is expressed
as 0xF30C.
Some parameters cannot be modified when the AC drive is running. Some parameters
cannot be modified regardless of status of the AC drive. In addition, pay attention to
setting range, unit and description of parameters when modifying them
Parameter Group
Visited Address
Parameter Address in RAM
F0 to FE
0xF000 to 0xFEFF
0x0000 to 0x0EFF
A0 to AC
0xA000 to 0xACFF
0x4000 to 0x4CFF
U0
0x7000 to 0x70FF
B.9 RULES FOR PARAMETER ADDRESS MARKING
Notes: Group FF: These are factory parameters. The parameters cannot be read or changed.
Group U: These parameters can only be read.
Notes: Frequent storage to the EEPROM reduces its service life. Therefore, in communication
mode, users can change values of certain parameters in RAM rather than storing the setting.
For group F parameters, users only need to change high order F of the function code address to
0. For group A parameters, users only need to change high order A of the function code address
to 4. The function code addresses are expressed as follows:
High-order bytes: 00 to 0F (group F), 40 to 4F (group A)
Low-order bytes: 00 to FF
