text: <s>[INST] PowerFlex 400 Multiple Speed Sources Summary: Want two sources of speed Analog In and a PresetIs it possible to have multiple speed sources for the PowerFlex 400? What I'm trying to accomplish is to have a pump run normally throughout the day with the Analog In signal as the speed source. This is how it works now. Have a selector switch run the pump at max speed for clean up at night. For reference here is what I have: P035 - 80.0 Hz [Max Hz] P036 - 2 [2 Wire Start] P038 - Started out at 2 [Analog In 1], this is where I tried to set it up at 4 [Preset Freq] P039 - 30.0 Sec [Accel Time] P040 - 30.0 Sec [Deccel Time] T051 - 8 [Preset Frequency] T052 - 14 [Anlg1 InCtrl] T069 - 2 (4-20mA) [Analog In 1 Select] A144 - 80.0 Hz [Preset Frequecy 1] I have a switch going from the jumper of 01/11 to 02. This starts the drive. This works as desired. The Analog In for the speed reference is on terminals 13 (+) and 14 (Com). This is the speed reference. This works also as desired. What I tried to do was have a 2 way selector switch with Terminal 04 [Digital Common] on one end and it would either make contact with Terminal 05 [Digital In 1] or Terminal 06 [Digital In 2]. This did not work. The drive wouldn't even move. So I put P038 back to 2, and it worked like it did before. The DIP switch is on SRC... Should I move the wires from Terminal 04 to Terminal 01/11? Is what I'm thinking possible? Thanks. [/INST] I just tested this and answered my own question. Yes the common wire should be from Terminal 01/11 not Terminal 04. I guess this could be helpful for anyone else who may need it. \\n </s>
