P14.00

Local communication address

The setting range: 1–247

When the master   is writing the frame, the communication address of the slave is set to 0; the   address is the communication address. All slaves on the Modbus fieldbus can   receive the frame, but the salve doesn’t answer.

The communication   of the drive is unique in the communication net. This is the fundamental for   the point to point communication between the upper monitor and the VFD.

Note: The address of the slave cannot set to 0.

Communication baud ratio

Set the digital   transmission speed between the upper monitor and the VFD.

0: 1200 BPS

1: 2400 BPS

2: 4800 BPS

3: 9600 BPS

4: 19200 BPS

5: 38400 BPS

6: 57600 BPS

7: 115200 BPS

Note: The baud rate between the upper PC and the VFD must be the same.   Otherwise, the communication is not applied. The bigger the baud rate, the   quicker the communication speed.

P14.02

Digital bit check

The data format   between the upper monitor and the VFD must be the same. Otherwise, the communication   is not applied.

0: No check (N, 8, 1) for RTU

1: Even check (E, 8, 1) for RTU

2: Odd check (O, 8, 1) for RTU

3: No check (N, 8, 2) for RTU

4: Even check (E, 8, 2) for RTU

5: Odd check (O, 8, 2) for RTU

P14.03

Answer delay

0–200 ms

The interval time   when the VFD receives the data and sent it to the upper monitor. If the   answer delay is shorter than the system processing time, then the answer   delay time is the system processing time, if the answer delay is longer than   the system processing time, then after the system deal with the data, waits   until achieving the answer delay time to send the data to the upper monitor

5 ms

P14.04

Fault time of communication overtime

0.0 (invalid), 0.1–60.0 s

When the function   code is set as 0.0, the communication overtime parameter is invalid

When the function   code is set as non-zero, if the interval time between two communications   exceeds the communication overtime, the system will report "485   communication faults" (CE).

Generally, set it   as invalid; set the parameter in the continuous communication to monitor the   communication state.

0.0 s

P14.05

Transmission fault processing

0: Alarm and stop freely

1: No alarm and continue to run

2: No alarm and stop according to the stop   mode (only under the communication control)

3: No alarm and stop according to the stop   mode (under all control modes)

0

P14.06

Communication processing

0x000–0x111

LED ones:

0: Write with response: the VFD will   respond to all reading and writing commands of the upper monitor.

1: Write without response: the VFD only   responds to the reading command rather than the writing command of the drive,   thus improving communication efficiency.

LED tens:

0: Communication encrypting invalid

1: Communication encrypting valid

LED hundreds:

0: Function code parameters changed by   communication are stored during Poff;

1: Function codes are stored based on the   MSB of communication address (1 or 0), which means the function codes will be   stored during Pof if the MSB is 1 or stored immediately if the MSB is 0.
