TERMINAL CODE                                FUNCTION DESCRIPTION

r s t                                         power supply input terminal ' it connects to 3- phase ac power supply or                                                single phase ac power supply.


u v w                                     are inverter's output terminal.it connects to 3 phase ac motor


-  +                                        connects to the connecting terminal of braking unit. - + they are
                                             respectively the dc bus's anode and cathode.


+, pb                                     braking  resistor connecting terminal.one end of the resistor connects to
                                             +; the other end connects to pb



G                                        g grounding terminal;connecting to the grounding.
