H30 Serial link (Function select)
H 3 0 L I N K F U N C
Setting range: 0 to 3
The link function (communication) provides a standard
RS485 serial interface and optional fieldbus connections.
The serial link function includes:
1) Monitoring (data monitoring, function data check)
2) Frequency setting
3) Operation command (FWD, REV, and other com-
mands for digital input)
4) Write function data
Communication can be enabled and disabled by a digital
input. This function sets the serial link function when
communication is enabled.

3 Enabled
The data monitoring and write functions are always
enabled. Disabling communication by a digital input
produces the same results as if this function were set to 0.
If the bus option is installed, this setting selects the bus
function, and the RS485 interface is restricted to monitor-
ing and writing function data. If the bus option is not
installed, this setting selects the RS485 function.
H31 RS485 (Address)
H39 RS485 (Response interval)
These functions set the conditions for RS485 RTU serial
communication. Set the conditions according to the host
device.
H 3 1 A D D R E S S
Setting range: 1 to 247
This function sets the station address of RTU.
Maximum connected devices is 31 for an RS-485 network.
H 3 2 M O D E O N
Setting range: 0 to 3
These functions configure the drive behavior in the event
of a communication error.

H 3 7 S T O P B I T S
This function sets the stop bit
Value Stop Bit
0 2 bits
1 1 bit
The stop bit is automatically configured by the value of the
parity bit. For parity "NONE" the stop bit is 2 bits. For
parity "EVEN" or "ODD" the stop bit is 1 bit.
