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:

CIRCUIT COMMON

The TB-2 terminals are internally tied together

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.
