 Used to control on, off operation of electronic brake of a load system. It only operates when set

value of control mode(H 40) is 0 (V/F control). Build sequence after checking set control mode.

 When brake control is in operation, DC brake and dwell run do not operate when starting up.

 Brake open Sequence

 When the electric motor is given instructions to run, the inverter accelerates CW or CCW to the

brake open frequency (I 84, I 85). After reaching the brake open frequency, the current running

through the motor reaches brake open current(I82) and puts out brake open signals to multi-

function output terminals or output relays that are set for brake control.

 Brake close sequence

 During run, the electric motor decelerates when stop instruction is given. When output

frequency reaches brake close frequency, it stops decelerating and puts out brake close signal

to the set output terminal. Frequency turns “0” after keeping the frequency for brake close delay

time(I86).
