If the response message is as below:
Example 2: set the ACC time of 01H inverter as 10s and the DEC time as 20s
ACC time means the time needed if the inverter speeds up from 0Hz to the
P00.11 ACC time 1
Max. One (P00.03).
DEC time means the time needed if the inverter speeds down from the Max.
Output frequency to 0Hz (P00.03).
Goodrive300 series inverters define four groups of ACC/DEC time which can
P00.12 DEC time 1
be selected by P05. The factory default ACC/DEC time of the inverter is the
first group.
Setting range of P00.11 and P00.12:0.0~3600.0s
The corresponding address of P00.11 is 000B, the ACC time of 10s corresponds to 0064H,
and the DEC time of 20s corresponds to 00C8H.
The command sent to the inverter:
If the response message is as below:
Note: The space between above commands is for instruction and there is no space between
the commands during actual applications.

10.5 Common communication fault

Common communication faults: no response to the communication or the inverter returns
abnormal fault.
The possible reason for no response to the communication:
Selecting wrong serial interface, for example, if the converter is COM1, selecting COM2
during the communication
The baud rate, digital bit, end bit and check bit are not the same with the inverter + and - of
RS485 are connected in reverse.
The 485 wire cap on the terminal board of the inverter is not plug in. the wire cap in behind
the terminal arrangement.
