Parameter Group
-69-
Description
Defines the format of Modbus data transmitted between the host controller and AC drive. Note that
the data format set in the host controller must be the same as that set in the AC drive. Otherwise,
communication will fail.
FD-02
RS485 local address
Address:
64770
Min.:
1
Unit:
-
Max.: 127 Data type: UInt16
Default:
16
Change: Unchangeable
Value Range:
1 to 127
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 host controller.
FD-03
RS485 response delay
Address:
64771
Min.:
0
Unit:
ms
Max.: 20 Data type: UInt16
Default:
2
Change:
At once
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
RS485 communication timeout time
Address:
64772
Min.:
0.0
Unit:
s
Max.: 60.0 Data type: UInt16
Default:
0.0
Change:
At once
Value Range:
0.0s to 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 a valid value, if the communication interval between current communication and the
next communication exceeds the value of Fd-04 (Modbus communication interruption detection
time), the system reports a communication fault (E16.01).
FD-06
Communication fault auto reset
Address:
64774
Min.:
0
Unit:
-
Max.: 1 Data type: UInt16
