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 PRESET SPEED #3
setting. Opens if the output frequency is equal to or less than 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 (see Parameter 25).
09
AUTOMATIC SPEED MODE: Closes if an AUTOMATIC (terminal strip) speed reference is
active. Opens if a STANDARD (Parameter 5) speed reference is active.
10
REVERSE: Closes when reverse rotation is active. Opens when forward rotation is active. (see
Parameter 17 - ROTATION DIRECTION).

TB-30 ANALOG OUTPUT
Terminal TB-30 can be used as an analog output proportional to either output frequency or load.
FREQUENCY SCALING (Parameter 40) or LOAD SCALING (Parameter 41) can be used to scale
the output signal.

0-10 VDC LOAD
05
2-10 VDC LOAD
NOTE: The 2-10 VDC signal can be converted to a 4-20 mA signal by connecting a resistor in series
with the signal such that the total load resistance is 500 Ohms. However, this output cannot be used with
devices that derive power from a 4-20 mA signal.
P09
TB-31 ANALOG OUTPUT
Terminal TB-31 can be used as an analog output proportional to load, or as the control signal to activate
the optional external Dynamic Braking module. LOAD SCALING (Parameter 41) can be used to scale
the output signal when TB-31 is used as an analog output proportional to load.

DYNAMIC BRAKING: TB-31 becomes the “trigger” that activates the optional external
Dynamic Braking module. Refer to the instructions included with the Dynamic Braking option.
NOTE: The 2-10 VDC signal can be converted to a 4-20 mA signal by connecting a resistor in series
with the signal such that the total load resistance is 500 Ohms. However, this output cannot be used with
devices that derive power from a 4-20 mA signal.
