TB-13A FUNCTION SELECT

This selects the function of terminal TB-13A. Closing TB-13A to TB-4 (or opening in the case of
settings 7 and 10) activates the selected function. The following functions can be selected:

NONE: Disables the TB-13A function.

0-10 VDC: Selects a 0-10 VDC signal (at TB-5/25) as the AUTO speed reference input.

4-20 mA: Selects a 4-20 mA signal (at TB-5/25) as the AUTO speed reference input.

PRESET SPEED #1: Selects PRESET SPEED #1 as the AUTO speed reference. The drive will
operate at the frequency programmed into Parameter 31.

RUN REVERSE: Close TB-13A to TB-4 to RUN in the reverse direction, and open to STOP.
This setting forces TB-12 to act as RUN FWD, requiring a maintained contact to RUN in the
forward direction. TB-1 must be closed to TB-4 for this function to operate.

START REVERSE: Momentarily close TB-13A to TB-4 to START the drive in the reverse
direction. Momentarily open TB-1 to TB-4 to STOP. This setting forces TB-12 to act as
START FWD, requiring a momentary contact to START in the forward direction.

EXTERNAL FAULT: Sets TB-13A as a normally closed external fault input. If TB-13A is
open with respect to TB-4, the drive will fault.

Factory Reserved: Equivalent to NONE (01).

DB FAULT: Sets TB-13A as a dynamic braking fault input when using the optional dynamic
braking module. When this input is activated by the dynamic braking module, the drive will
trip into a "dF" fault and the motor will coast to a stop. Refer to the manual included with the
Dynamic Braking option.

AUXILIARY STOP: When TB-13A is opened with respect to TB-4, the drive will decelerate
to a STOP (even if STOP METHOD is set to COAST) at the rate set into Parameter 42 - ACCEL/
DECEL #2.

ACCEL/DECEL #2: Selects the acceleration and deceleration time programmed into Parameter
42 - ACCEL/DECEL #2.

NOTE: In order for the RUN REVERSE and START REVERSE functions to operate, Parameter 17
- ROTATION DIRECTION must be set to FORWARD AND REVERSE (02).

TB-13B FUNCTION SELECT

This selects the function of terminal TB-13B. Closing TB-13B to TB-4 (or opening in the case of
setting 08) activates the selected function. The following functions can be selected:

NONE: Disables the TB-13B function.
