Communication
‑693‑
For groups A0 to AF, the high‑order 8 bits in the communication address are 40 to
4F or A0 to AF, which is decided by whether the high‑order 8 bits are written to
EEPROM. The low‑order 8 bits indicate the parameter number in the group.
Take writing AC‑08 as an example.
If it is not be written to EEPROM, the communication address is 4C08H.
If it is written to EEPROM, the communication address is AC08H.

1. Status data
Status data includes group U (monitoring parameters), AC drive fault description,
and AC drive operation status.
● Group U (monitoring parameters)
For U0 to UF, the high‑order 8 bits in its communication address is 70 to 7F, and
the low‑order 8 bits indicate the parameter number in the group. For example,
the communication address of U0‑11 is 700BH.
● AC drive fault description
When the AC drive fault description is read via communication, the
communication address is 8000H. The host controller can obtain the current
fault code of the AC drive by reading the address. For the fault code description,
see the definition of F9‑14.
● AC drive operation status
When the AC drive running status is read via communication, the
communication address is 3000H. The host controller can obtain the current
operation status of the AC drive by reading the address. The operation status is
defined in the following table.
