7.4 Definition of Communication Data Address
The drive supports four communication protocols (Modbus-RTU, CANopen, CANlink, and PROFIBUS-
DP). The user programmable card and point-to-point communication are derivation of CANlink protocol.
Host computer can implement control such as monitoring and parameter viewing and modification on
the AC drive through their protocols.
The drive's communication data is classified into parameter data and non-parameter data. The non-
parameter data includes running commands, running status, running parameters and alarm information.
7.4.1 Parameter Data
The parameter data provides important parameters of the AC drive. The parameter data is
described as below:
Parameter data Group F (read-write) F0, F1, F2, F3, F4, F5, F6, F7, F8, F9, FA, FB,
FC, FD, FE, FF
Group A (read-write) A0, A1, A2, A3, A4, A5, A6, A7, A8, A9, AA, AB,
AC, AD, AE, AF
Communication addresses of parameter data are defined as follows:
1. When parameter data is read by means of communication
For groups F0 to FF and A0 to AF, the high 16 bits of the communication address indicate the
group number and the low 16 bits indicate the parameter number in the group.
Example:
Communication address of F0-16 is F010H, where F0H represents group F0 and 10H is the
hexadecimal data format of serial number 16 in the group.
Communication address of AC-08 is AC08H, where ACH represents group AC and 08H is
the hexadecimal data format of serial number 8 in the group.
2. When parameter data is written by means of communication
For groups F0 to FF, whether the high 16 bits in communication address are 00 to 0F or F0
to FF is decided by whether the high 16 bits are written to EEPROM. The low 16 bits indicate
parameter number in the group.
Example:
F0-16: If it need not be written to EEPROM, communication address is 0010H. If it needs to
be written to EEPROM, communication address is F010H.
For groups A0 to AF, whether the high 16 bits in communication address are 40 to 4F or A0
to AF is decided by whether the high 16 bits are written to EEPROM. The low 16 bits indicate
parameter number in the group.
AC-08: If it need not be written to EEPROM, communication address is 4C08H. If it needs to
be written to EEPROM, communication address is AC08H.
