ROTATION
(ROTATION DIRECTION)
WARNING!
If TB-13C is programmed for RUN REVERSE, TB-1 is disabled and CANNOT
be used as a STOP switch! This is true in LOCAL and REMOTE mode.
Incorrect use of TB-1 may result in damage to equipment and/or injury to
personnel! Refer to Parameter 49 - TB13C for more information
.
This parameter is used to limit the motor rotation direction to forward or reverse, or
to allow rotation in both directions. The parameter can be set to one of the following:
FORWARD
Rotation is allowed in the forward direction only. This selection
disables the FWD/REV button on the keypad and TB-13C
(REVERSE).
REVERSE
Rotation is allowed in the reverse direction only. This selection
disables the FWD/REV button on the keypad and TB-12A
(FORWARD). TB-13C must be programmed for either RUN REV
or STRT REV for this function to operate in the REMOTE mode.
FWD&REV
Rotation is allowed in both directions. The FWD/REV button is
enabled. Rotation can be changed from the keypad (LOCAL
mode), or the terminal strip (REMOTE mode). In the REMOTE
mode, TB-13C must be programmed for either RUN REV or
STRT REV for this function to operate.
FWD@LOC
In LOCAL mode, rotation is allowed in the forward direction only.
In REMOTE mode, rotation is allowed in both directions.
NOTE: If the rotation is changed while the drive is running, the drive will decelerate to
0 Hz, and then accelerate back up to the speed set point in the opposite direction.
28
AUTO / MAN
(AUTO / MANUAL SPEED CONTROL)
This parameter is used to select the method of speed control when the drive is in
the LOCAL mode. The choices are explained below:
MANUAL
The drive will accept a speed reference from the keypad (UP
and DOWN ARROW keys) or a speed potentiometer (wired
to TB-2, 5A, and 6). Parameter 29 - MANUAL below selects
either keypad or speed potentiometer. The AUTO/MAN button
on the keypad is disabled.
AUTO
The drive will accept a 0-10 VDC input signal on TB-5A and
TB-2, a 4-20 mA input signal on TB-5B and TB-2, or one of the
four PRESET SPEEDS. The programming of TB-13A, TB-13B
and TB-13C determines which AUTO reference is selected.
The AUTO/MAN button on the keypad is disabled.
BOTH
The AUTO/MAN key on the keypad is enabled and can be
used to toggle between MANUAL and AUTO control ONLY if
the drive is in LOCAL mode.
NOTE: If the drive is in the AUTO mode, and a speed reference is not selected
using TB-13A, TB-13B, or TB-13C, the speed reference source will default to the
setting of Parameter 29 - MANUAL (KEYPAD or 0-10 VDC).
29
MANUAL
(MANUAL)
This parameter selects the speed reference source when the drive is set for MANUAL
speed control (see Parameter 28 - AUTO/MAN above). The speed reference options
are KEYPAD (UP and DOWN ARROW keys), or 0 - 10 VDC (from a speed pot wired
to TB-2, 5A, and 6; or some other 0-10 VDC source).
