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:
NOTES:
1. Program the preset speeds to the desired values (see Parameters 1-4:
SPEED #1 - #4).
2. Program TB-13A to select SPEED #1, TB-13B to select SPEED #2, and TB-13C to select
SPEED #3 (see Parameters 47, 48 and 49).
3. To select a preset speed, close the appropriate preset speed terminal to TB-2. To select
SPEED #4, close any two of the three preset speed terminals to TB-2.
4. For speed pot control, one of the TB-13 terminals needs to be programmed to select 0-10
VDC. Close the selected TB-13 terminal to TB-2 for speed pot control. This will result
in the loss of one of the preset speeds.
5. If none of the preset speeds (or the speed pot) are selected via contact closures, the drive
will default to keypad speed control.
