 Used to control on, off operation of electronic brake of a load system. It only operates when
the set value of control mode (H40) is 0 (V/F control). Build sequence after checking set
control mode.
 When the brake control is operating, 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 (I84, I85). 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).
