27 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 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 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).
