[Dc-brake]
DC Injection Braking can be activated during inverter
stopped by configuring one of the multi-function input
terminals (P1, P2, P3) to ‘Dc-bake’. To activate the DC
Injection Braking, close the contact on the assigned
terminal while the inverter is stopped.
[Exchange]
Exchange is used to bypass the motor from the inverter
line to commercial power or the opposite. To bypass the
motor to commercial line, set the ‘Exchange’ function in
multi-function output terminal and ‘INV line’, ‘COMM line’
function in multi-function output terminal. Speed search
function (FU2-22) is activated automatically during
exchanging operation.
