Setting data length
Setting parity bits
Setting stop bits
In a system where the local station is always surely accessed
within a specific time, this function detects that access was
stopped due to an open-circuit or other fault and invoke an Er8
trip.
Setting range: 0: No detection
1 to 60s
Setting transmission speed
Setting action when occurring error and value of timer for the

4.8.2 Time of receiving preparation completion
This defines the time from returning the response to complet-
ing receiving preparation of the input port in the inverter.

4.9 Function
■
H30 Serial link (Function select)
The link function (communication function) can connect RS-
485 (provided as standard) to various bus connections
(option).
The link function includes:
1) Monitoring (various data monitoring and function data
check)
2) Frequency setting
3) Operation commands
(Commands such as FWD and REV set at the digital
inputs)
4) Writing function data
Setting link function when communication is valid
Monitoring function and writing function data function are
always valid. If making the communication of digital input
invalid, the state becomes similar to 0 of the setting value.
When option related to busses is provided, this setting in the
function becomes the function selecting of the option, and the
function of RS-485 is restricted only to monitoring and writing
function data. When not providing option, this setting becomes
function selecting of RS-485.

H39 RS-485 (Response interval)
These set various conditions of the communication through
RS-485. Set these so as to match with upstream devices. For
the protocols, refer to the technical manual.
