9 Function
♦
The link function (communication function) can
connect RS485 (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

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
RS485 is restricted only to monitoring and writing
function data. When not providing option, this setting
becomes function selecting of
ＲＳ
485
.
These set various conditions of the communication
through RS485. Set these so as to match with
upstream devices. For the protocols, refer to the
technical manual.
