11.4 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 pushbuttons) for START and STOP commands.

START CONTACT
The TB-2 terminals are internally connected to each other
NOTE
Momentarily close TB-12 to TB-2 to START the drive, and momentarily
open TB-1 to TB-2 to STOP the drive.
If reverse direction is also required, ROTATION DIRECTION (Parameter
17) must be set to FORWARD AND REVERSE (02), and TB-13A
(Parameter 10) must be set to START REVERSE (06). If the FWD/REV
switch is changed while the drive is running, the drive will not change
direction until the START button is pushed. If reverse direction is not
required, the other side of the START pushbutton must be wired
directly to TB-12.
For 0-10 VDC or 4-20 mA speed control, use one of the following
methods:
- Program one of the TB-13 terminals (13A, 13B, or 13C) for 0-10
VDC (02) or 4-20 mA (03). When that TB-13 terminal is closed to
TB-2, the drive will respond to the selected speed reference signal.
If that TB-13 terminal is not closed to TB-2, the drive will respond to
the speed control source selected in Parameter 05 - STANDARD
SPEED SOURCE. This method must be used if it is necessary to
toggle between two speed sources.
- Program Parameter 05 - STANDARD SPEED SOURCE for 0-10 VDC
(03) or 4-20 mA (04). This method is preferable if only one speed
source is required, as this method leaves the TB-13 terminals free to
be used for other functions.
