15.3 THREE-WIRE START/STOP CONTROL
Shown below is the wiring diagram for a typical three-wire start/stop control scheme,
using momentary contacts (such as push buttons) for START and STOP commands.
Also shown is the wiring for a 0-10 VDC or 4-20 mA speed reference signal.

START CONTACT
The TB-2 terminals are internally tied together
NOTE
1. Momentarily close TB-12A to TB-2 to START, and momentarily
open TB-1 to TB-2 to STOP.
2. If REVERSE direction is required, ROTATION must be set to
FWD&REV, and TB-13C must be set to START REVERSE (refer
to Parameters: 27 - ROTATION, and 49 - TB13C).
If REVERSE is not required, wire the Start button directly to
TB-12A and eliminate the FWD/REV switch.
3. Program TB-13A, 13B, or 13C to select the appropriate speed
reference signal that will control the drive speed (refer to
Parameters 47, 48, and 49). When that TB-13 terminal is closed
to TB-2, the drive will respond to the selected speed reference
signal. In the diagram above, TB-13A is programmed to select
either a 0-10 VDC or 4-20 mA signal.
4. If the contact closure is not made between TB-13A and TB-2 to
select a speed reference, the drive will default to MANUAL speed
control, which is determined by Parameter 29 - MANUAL.
