ROTATION
(ROTATION DIRECTION)
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 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 form 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.
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 three 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 Parameter 30 - CONTROL is set to LOCAL.
NOTE:
If this parameter is set to AUTO or BOTH, and a speed reference is not selected by a contact
closure between TB-13A, TB-13B, or TB-13C and TB-2, the speed reference will default to the setting of
Parameter 29 - MANUAL (KEYPAD or 0-10 VDC).
