P144 Digital Output
Inversion
Used to invert the selections for
P140 (Relay Output) and P142 (TB-14
Output).
EXAMPLE: When P140 = 6 (AT
SPEED), the relay is energized when
output frequency = commanded
frequency. IF P144 = 1 or 3, then
P140 is inverted (INVERSE AT SPEED)
and the relay is energized when the
output frequency does not equal the
command frequency.
NOTE
Inverting P140 or P142 when the parameter is set to NONE (0) will
result in the output being energized continuously.
NOTE
For SM Vector drives rated at 0.33 to 10 HP (0.25 to 7.5 kW), P144 is
only available with software versions 3.0 and higher (refer to P501).
P145 Loss of Load
Threshold
0 0 {%} 200 P140, P142 = 10: Output will energize
if motor load falls below P145 value
longer than P146 time

P149 Analog Offset 0.0 0 {%} 100 Scaled value. Example: P149 = 10%,
Scaled variable = freq., P150 = 1, P152
= 60Hz; then TB30 = 0VDC below 6HZ
P150 TB-30 Output 0 0 None 2-10 VDC signal can be converted
to 4-20 mA with a total circuit
impedance of 500 Ω

4 2-10 VDC Load
5 0-10 VDC Torque
6 2-10 VDC Torque
7 0-10 VDC Power (kW)
8 2-10 VDC Power (kW)
9 Network Controlled
Requires optional communication
module (refer to the network module
documentation).
10 Sequencer Controlled Value set in individual sequencer
segments
P152 TB-30 Scaling:
Frequency
60.0 3.0 {Hz} 2000 If P150 = 1 or 2, sets the frequency at
which output equals 10 VDC
P153 TB-30 Scaling:
Load
200 10 {%} 500 If P150 = 3 or 4, sets the Load (as
a percent of drive current rating) at
which output equals 10 VDC.
