address
Example 2: set the ACC time of 01H VFD as 10s and the DEC time as 20s.
P00.11 ACC time 1
P00.12 DEC time 1
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.

10.4.8.4 Modbus communication debugging instance
A PC is used as the host, an RS232-RS485 converter is used for signal conversion, and the PC serial
port used by the converter is COM1 (a RS232 port). The upper computer commissioning software is
the serial port commissioning assistant Commix, which can be downloaded from the Internet.
Download a version that can automatically execute the CRC check function. The following figure
shows the interface of Commix.

ACC time means the time needed if the VFD speeds
up from 0Hz to the Max. One (P00.03).
DEC time means the time needed if the VFD speeds
down from the Max. Output frequency to 0Hz
(P00.03).
Goodrive300 series VFDs define four groups of
ACC/DEC time which can be selected by P05. The
factory default ACC/DEC time of the VFD is the first
group.
