05 FAULT LOCKOUT: Closes when input power is applied. Opens if three restart

attempts are unsuccessful, or if input power is removed.

06 AT SET SPEED: Closes if the drive is within + 0.5 Hz of the speed setpoint.

07 ABOVE PRESET SPEED #3: Closes if the output frequency exceeds the value

in PRESET SPEED #3. Opens if the output frequency is equal to or less than

the value in PRESET SPEED #3 (Parameter 33).

08 CURRENT LIMIT: Closes if the output current exceeds the CURRENT LIMIT

setting. Opens if the output current is equal to or less than CURRENT LIMIT

(refer to Parameter 25).

09 AUTOMATIC SPEED MODE: Closes if an AUTOMATIC (terminal strip) speed

reference is selected using TB-13A, 13B, 13C, or 13D. Opens if a STANDARD

(Parameter 5) speed reference is active.

10 REVERSE: Closes when reverse rotation is active. Opens when forward rotation

is active. (Refer to Parameter 17 - ROTATION DIRECTION).

11 DYNAMIC BRAKING: Used to "trigger" the optional external Dynamic Braking

module. Refer to the instructions included with the Dynamic Braking option.

P07 BIPOLAR REFERENCE SELECTION

This parameter is used to enable the -10 to +10 VDC bipolar speed reference input (cannot

be used as a torque reference). Refer to Section 11.6 for -10 to +10 VDC wiring examples.

01 DISABLE: The drive will operate normally and respond to the speed reference

selected in Parameter 5 - STANDARD REFERENCE SOURCE, or selected

using terminals 13A, 13B, 13C, and 13D. Refer to Section 10.6 for more

information on speed reference selection.

02 ENABLE: The drive will only respond to a -10 to +10 VDC bipolar signal (all

other speed references are disabled).

From +0.1 to +10 VDC the drive will operate in the Forward direction, with the

maximum speed determined by SPEED AT MAX SIGNAL (Parameter 46) or

MAXIMUM FREQUENCY (Parameter 24), whichever is lower.

From -0.1 to -10 VDC, the drive will operate in the Reverse direction, with the

maximum speed determined by SPEED AT MIN SIGNAL (Parameter 45) or

MAXIMUM FREQUENCY (Parameter 24), whichever is lower.

NOTE

• When setting 02 is selected, Parameter 17 - ROTATION must be set to

FORWARD AND REVERSE (02) for the bipolar speed reference to work

properly.

• When setting 02 is selected, the RUN and START functions on terminals

TB-13A and TB-13D can only be used to start the drive; they will no longer

select direction (direction is only determined by the polarity of the -10 to

+10 VDC signal). However, TB-13B and TB-13C can still be used for JOG

FORWARD and JOG REVERSE functions.
