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 .
