Parameter Groups
‑303‑
Max.: 247 Data type: UInt16
Default:
1
Change: In real time
Value Range:
1 to 247
Description
When the local address is set to 0 (broadcast address), host controller broadcast
is enabled.
The local address must be unique in the range of 1 to 247, which is the basis for
point‑point communication between the AC drive and the host controller.
FD-03
Response delay
Address:
0xFD03
Min.:
0
Unit:
ms
Max.: 20 Data type: UInt16
Default:
2
Change: In real time
Value Range:
0 ms to 20 ms
Description
This parameter defines the interval from the end of data receiving by the AC drive
to the start of data transmission to the host controller.
If the response delay is shorter than the system processing time, the system
processing time prevails, which means the system sends data to the host
controller immediately after data processing is completed. If the response delay is
longer than the system processing time, the AC drive sends data to the host
controller only after the response delay elapses.
FD-04
Modbus communication timeout time
Address:
0xFD04
Min.:
0
Unit:
s
Max.: 60 Data type: UInt16
Default:
0
Change: In real time
Value Range:
0.0s–60.0s
Description
When it is set to 0.0s, the Modbus communication timeout time is invalid. It is set
to 0.0s under normal circumstances. This parameter is used to monitor
communication status in a system with continuous communication.
When it is set to an effective value, if the time interval between the current
communication and the next communication exceeds Fd‑04 (Modbus
communication interruption detection time), the system reports a
communication fault (Err16).
