15.2 KEYPAD H/O/A
When the drive is in Keypad H/O/A mode, the AUTO (START) key on the keypad is used
to put the drive into AUTO mode. The drive will then respond to start/stop commands
from the terminal strip. The start/stop circuit is wired as shown below. Also shown is the
wiring for a 4-20 mA or 0-10 VDC speed reference signal.

NOTES:
1.
Close TB-1 to TB-2 to RUN, and open to STOP.
2. When the drive is put into AUTO mode, the speed reference will be determined
by AUTO SOURCE (Parameter 24). In the example above, the AUTO speed
reference is either a 4-20 mA or 0-10 VDC signal.
3. When HAND mode is selected, the drive starts immediately. TB-1 has no effect.
