I'm trying to figure out how I can have a motor ran at one speed then throw a switch and have the motor ran at another speed with the controlling the DI3-DI6 inputs. Can anyone please help me?

If you are using DI1 and possibly DI2 as the run (stop/start), then you can use the multi speed programming on the DI3-DI6 inputs.

P3.00 needs to be either 01, 02

P3.01 needs to be either 00, 01, 02, and the proper external switches need to be wired correctly to the DI1 and possibly DI2 inputs

P3.02 is the programing point for DI3 if it is set for 03 it will be the least most significant bit of a binary number.

P3.03 is the programming point for DI4, if it is set for 04 it will be the second bit of a binary number.

P3.03 is the programming point for DI5, if it is set for 05 it will be the most significant bit of a binary number.

On page 4-25 of the GS2 manual there is a matrix chart that shows the combinations of bit1, bit2, bit3 and their relationship to the preset speeds.

Depending on what you choose your programming to be the parameters below would be set to your desire.

P5.01 preset speed1 ( you set the Hz)

P5.02 preset speed2 ( you set the Hz)

P5.03 preset speed3 ( you set the Hz)

P5.04 preset speed4 ( you set the Hz)

P5.05 preset speed5 ( you set the Hz)

P5.06 preset speed6 ( you set the Hz)

P5.06 preset speed7 ( you set the Hz)

P5.07 preset speed8 ( you set the Hz)

In your case I would suggest one of two scenarios

1. Use a speed pot or the keypad to control the speed without the external switch (P4.00 = 00, 01, 02). When the switch is made on DI3 (with P3.02 set to 03) the preset speed you programmed into P5.01 would now be the present commanded speed.

2. Wire a jumper between DCM and DI3. Wire the switch between DCM and DI4. Set P5.01 to your base speed and P5.03 to the speed you want with the switch on. Lastly program P3.02 = 03 and P3.03 = 04.
