DB FAULT: Sets TB-13A as a dynamic braking fault input when used with 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 instructions included with
the Dynamic Braking option.

AUXILIARY STOP: When TB-13A is opened with respect to TB-11, the drive will decelerate
to a STOP (even if STOP METHOD is set to COAST) at the rate set into ACCEL/DECEL #2
(Parameter 42).

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

NOTE: If the optional remote keypad is used, functions 02, 04, 05, and 06 are disabled. Therefore,
if this terminal is not being used for any of the other functions, it should be set to NONE (01).

TB-13B FUNCTION SELECT

This selects the function of terminal TB-13B. Closing TB-13B to TB-11 (or opening in the case of
settings 07 and 09) activates the selected function. The following functions can be selected:

NONE: Disables the TB-13B function.

SPEED POT: Selects a speed pot as the speed reference input. Refer to Section 11.0 for speed
pot wiring.

PRESET SPEED #2: Selects PRESET SPEED #2 as the speed reference. The drive will operate
at the frequency programmed into Parameter 32.

DECREASE FREQ: Closing TB-13B to TB-11 will decrease the speed setpoint until the contact
is opened. TB-13C must be programmed for INCREASE FREQ.

JOG FORWARD: Close TB-13B to TB-11 to JOG in the forward direction. The drive will run
at PRESET SPEED #2 (Parameter 32) when in JOG mode.

JOG REVERSE: Close TB-13B to TB-11 to JOG in the reverse direction. The drive will run at
PRESET SPEED #2 (Parameter 32) when in JOG mode.

EXTERNAL FAULT: Sets TB-13B as a normally closed external fault input. Open TB-13B to
TB-11 to trip the drive.

WARNING!

When operating in JOG mode, the STOP signal and the AUXILIARY STOP function (see Parameters
10-12) WILL NOT stop the drive. To stop the drive, remove the JOG command.

JOG REVERSE will operate the drive in reverse rotation even if ROTATION DIRECTION (Parameter
17) is set to FORWARD ONLY.
