text: <s>[INST] Control of ultra 3000 index drive I am going to use ultra 3000 index drive to control a movement on condition from the first spot to the second pot and back to the first spot.Back and forth repeatedly.I want to use preset position mode.I can set the second spot as preset postion 0 and the first spot as preset position 1.I also need to set drive input to active drive move to preset positon.From the manual,it said i have to set digial input 8 as preset select 0.When it is off ,drive controllded motor moves to preset posion 0.When it is on motor moves to preset posion 1.I donot want to control a movement between two places deponding on change of status (off /on)on only one input.I'd like to control a movement just when one input is on. When it is off ,nothing to do.Can I use preset posion 1 and 2,also preset select 1 and 2 on digital input 7 and 6?So I donot need to use preset posion 0 and preset select 0 for input 8.Thus,only when input 7 is on goes to preset posion 1 and only when input 6 is on goes to preset position 2 and back and forth.Can anybody help me with this?Thanks [/INST] Derek, first some considerations taken from U3K manuals... Preset Selects 0 through 5 contribute a binary value when a digital input becomes active. The drive sums the binary values and uses the resulting integer to determine which Preset to activate. The drive uses only the Preset Select 0, 1 and 2 binary values (yielding values 0 – 7) when the drive’s Operation mode is set to Preset Position, Preset Velocity, Preset Current and Preset Follower (Gearing Ratio). The digital input Preset Select binary values are as follows: • Preset Select 0 = 1 if active, 0 if not. • Preset Select 1 = 2 if active, 0 if not. • Preset Select 2 = 4 if active, 0 if not. So, if you activate only the input configured as Preset Select 1, you run Preset 2 (the binary value of this select is 2).Again, if you activate only the input configured as Preset Select 2, you run Preset 4. Well, to obtain what you want, you have to activate the input configured as Preset Select 0 to start Preset 1 and only Preset Select 1 when you want to start Preset 2. :smileysurprised: See also the attached table... Hope this helps... - fuzzy logic \\n </s>
