15.4 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:

NOTE
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.
