SPEED POT AND PRESET SPEED CONTROL

Shown below is the wiring diagram for a control scheme that utilizes a speed pot and PRESET SPEEDS for

speed control, and either a two-wire or three-wire START/STOP circuit:

NOTES:

1. Program the PRESET SPEEDS (Parameters 1-4) to the desired values.

2 . Program TB-13A to select SPEED #1, TB-13B to select SPEED #2, and TB-13C to select

SPEED #3 (refer to Parameters 47, 48, and 49)

3 . To select a preset speed, close the appropriate terminal to TB-2 . To select SPEED #4, close any two

of the preset speed terminals to TB-2 .

4 . Speed pot control can be selected by one of two methods . If none of the preset speeds are selected (all

TB-13 terminals are open), the drive will default to speed pot control if Parameter 29 - MANUAL is

set to 0-10 VDC . The speed pot can also be selected if one of the TB-13 terminals is programmed to

select 0-10 VDC and that terminal is closed to TB-2 .

5. If REVERSE rotation is required, TB-13C cannot be used to select SPEED #3. TB-13C must be

programmed to select RUN REVERSE or START REVERSE, leaving only TB-13A and TB-13B to

select preset speeds .
