27 ROTATION
(ROTATION DIRECTION)
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 setpoint 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.
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.
