8.11 Group H0: Communication
H0.00 Communication protocol
Setting range 0 ~ 1
Minimum unit 1
Factory default 0
● 0: ModBus
● 1: ModBus / PROFIBUS
It is ModBus for EFC3600-xKxx-xPx-MDA-7P-NNNN models; it is PROFIBUS for
EFC3600-xKxx-xPx-PDA-7P-NNNN models.
See chapter 13 "Communication Protocols" on page 184.
H0.01 Baud rate
Setting range 0 ~ 5
Minimum unit 1
Factory default 3
Used to set data transmission rate of ModBus communication between the ex-
ternal computer and the frequency converter. Available baud rate includes:
● 0: 1200 bps
● 1: 2400 bps
● 2: 4800 bps
● 3: 9600 bps
● 4: 19200 bps
● 5: 38400 bps
H0.02
Data format
Setting range 0 ~ 3
Minimum unit 1
Factory default 0
Used to set data format in ModBus protocol.
● 0: N, 8, 1 (1 start bit, 8 data bits, 1 stop bit, without check)
● 1: E, 8, 1 (1 start bit, 8 data bits, 1 stop bit, even parity)
● 2: O, 8, 1 (1 start bit, 8 data bits, 1 stop bit, odd parity)
● 3: N, 8, 2 (1 start bit, 8 data bits, 2 stop bits, without check)
The data format of the frequency converters must be the same as
that of the external computer; otherwise, normal communication is
impossible.
