text: <s>[INST] Powerflex 400 reversing enabled We have a powerflex 400 controlling a cooling tower fan which has the reversing feature enabled and it works fine, when we put it into reverse we stop the fan put the external switch to the reverse position and start the fan then it ramps up to maintain temperature.my questions are:1. If it is running in forward in Auto and the external switch is put to reverse will the VFD ramp down to 0hz and then begin to ramp up.2. When it is in reverse at 0hz and the hand button is depressed it switches to forward, Will it operate in hand when it is running in reverse. Thanks [/INST] Here the answers: 1. YES2. Direction is Forward unless an external input is programmed for Cmd Reverse (T051-T054) Hope this helps… - fuzzy logic \\n </s>
