The address of this unit has uniqueness (in addition to the broadcast address), which is the basis
of peer-to-peer communication for the host computer and the inverter.
F9.03
Response latency
The factory value
2ms
Set the range
0
～
20ms
Response time delay: refers to the interval time between the data receiving end of the frequency
converter and the sending data of the upward plane.If the response time delay is less than the system
processing time, the response time delay will be subject to system processing time, processing time,
such as response time delay is longer than system after processing the data, the system will delay
waiting, until the response delay time to up to a machine to send data.
F9.04
Communication timeout
The factory value
0.0 s
Set the range
0.0s(invalid )
；
0.1~60.0s
When the function code is set to 0.0s, the communication timeout parameter is
invalid.
When the function code is set to the valid value, if the interval between one
communication and the next communication exceeds the communication timeout period,
the system will report a communication failure error (fault serial number Err.16).Usually,
it is set to invalid.If the secondary parameters are set in a continuous communication
system, the communication status can be monitored.
F9.05
Communication protocol
selection
The factory value
1
Set the range
0
：
Non-standard Modbus protocol;
1. Standard Modbus protocol.
F9.05=1: select the standard Modbus protocol.
F9.05=0: when reading commands, the number of bytes returned from the machine is
one byte more than the standard Modbus protocol.
F9.06
Communication reads current
resolution.
The factory value
0
Set the range
0
：
0.01A
1
：
0.1A
Used to determine the output unit of the current when the communication reads the output
current.
