SPEED POT AND PRESET SPEED CONTROL

Shown below is the wiring for SPEED POT and/or PRESET SPEED control, and either a two-wire or
three-wire start/stop circuit:

NOTES:

1.

Program the PRESET SPEEDS (Parameters 31-37) to the desired values.

2.

Program TB-13A (Parameter 10) to PRESET SPEED #1 (04), TB-13B (Parameter 11) to PRESET
SPEED #2 (04), and TB-13C (Parameter 12) to PRESET SPEED #3 (04). To select a preset
speed, close the appropriate TB-13 terminal(s) to TB-2 (refer to Parameters 31-37 for the Preset
Speed Activation table).

3.

If reverse rotation is also required, TB-13A cannot be used as a PRESET SPEED SELECT. TB-
13A must be programmed to select RUN REVERSE (05) or START REVERSE (06), leaving
only TB-13B and TB-13C to select preset speeds.

4.

For speed pot control, program Parameter 05 - STANDARD SPEED SOURCE for 0-10 VDC
(03). If none of the preset speeds are selected (all of the TB-13 terminals are open), the drive will
respond to the speed pot.
