Cause : Emergency Override comes when emergency override is active or forward or reverse emergency override input is closed.

  1. When the Forward (H1-0X = 81) or Reverse (H1-0X = 82) Emergency Override multi-function input is closed, the drive will run at either the B1-14 reference (B1- 15 = 0) or the AUTO reference (B1-15 = 1) and “OVRD Emergency Override” will be dis- played on the digital operator.
  2. If the Drive Enable (H1-0X = 6A) or Bypass Drive Enable (H1- 0X = 70) is programmed, the emergency override function can only be activated when the Enable input is open. If the Enable input is closed at any time during emergency override, the drive will stop.
