S1 series standard inverter
-197-
Detailed parameter description
Acceleration time is the time needed for accelerating
from 0Hz to Max. output frequency (P00.03).
Deceleration time is the time needed from
decelerating from Max. output frequency (P00.03) to
0Hz.
S1 series inverter defines four groups of acceleration
and deceleration time, which can be selected via
multi-function digital input terminals (P05 group). The
acceleration/deceleration time of the inverter is the
first group by default.
Setting range of P00.11 and P00.12: 0.0–3600.0s
The address of P00.11 is 000B, 10s is 0064H in the hexadecimal form, and 20s is 00C8H in the
hexadecimal form.
The command transmitted by the master is as follows:

9.4.8.4 Modbus communication commissioning example
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 (an 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.
