Motor Speed Unit and par. 0-03 Regional Settings . The default settings of par. 0-02 Motor
Speed Unit
and par. 0-03 Regional Settings depend on which region of the world the adjustable frequency drive is supplied to but can be re-programmed
as required.

NOTE!
If [No Operation] is selected in par. 5-12
Terminal 27 Digital Input , no connection to +24 V on terminal 27 is necessary to enable start.
If [Coast Inverse] (factory default value) is selected in par. 5-12
Terminal 27 Digital Input , a connection to +24 V is necessary to enable
start.
5.1.2 RS-485 Bus Connection
One or more adjustable frequency drives can be connected to a controller
(or master) using the standard RS-485 interface. Terminal 68 is connec-
ted to the P signal (TX+, RX+), while terminal 69 is connected to the N
signal (TX-, RX-).
If more than one adjustable frequency drive is connected to a master,
use parallel connections.
