Chapter 6 - Parameter Description [I/O]

[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.

[Up, Down]

By using the Up and Down function, the drive can accelerate to a steady speed and decelerate down to a desired speed by using only two input terminals.
