S100 Brake Control

Brake control is used to control the On/Off operation of electronic brake load system.



  1. Brake release sequence: During motor stop state, if an operation command is entered, the inverter accelerates up to brake release frequency (Ad.44– 45) in forward or in reverse direction. After reaching brake release frequency, if motor current reaches brake release current (BR Rls Curr), the output relay or multi function output terminal for brake control sends a release signal. Once the signal has been sent, acceleration will begin after maintaining frequency for brake release delay time (BR Rls Dly).
  3. Brake engage sequence: If a stop command is sent during operation, the motor decelerates. Once the output frequency reaches brake engage frequency (BR Eng Fr), the motor stops deceleration and sends out a brake engage signal to a preset output terminal. Frequency is maintained for the brake engage delay time (BR Eng Dly) and will become 0 afterwards. If DC braking time (Ad.15) and DC braking resistance (Ad.16) are set, inverter output is blocked after DC braking.
