3–44
13 USP Unattended Start
Protection
ON On powerup, the inverter will not resume a Run
command (mostly used in the US)
OFF On powerup, the inverter will resume a Run
command that was active before power loss
15 SFT Software Lock ON The keypad and remote programming devices
are prevented from changing parameters
OFF The parameters may be edited and stored
16 AT Analog Input
Voltage/current
Select
ON Terminal [OI] is enabled for current input (uses
terminal [L] for power supply return)
OFF Terminal [O] is enabled for voltage input (uses
terminal [L] for power supply return)
18 RS Reset Inverter ON The trip condition is reset, the motor output is
turned OFF, and powerup reset is asserted
OFF Normal power-ON operation
19 PTC PTC Thermistor
Thermal Protection
ANLG When a thermistor is connected to terminals [6]
and [L], the inverter checks for over-
temperature and will cause trip event and turn
OFF output to motor
OPEN A disconnect of the thermistor causes a trip
event, and the inverter turns OFF the motor
20 STA Start
(3-wire interface)
ON Starts the motor rotation
OFF No change to present motor status
21 STP Stop
(3-wire interface)
ON Stops the motor rotation
OFF No change to present motor status
22 F/R FWD, REV
(3-wire interface)
ON Selects the direction of motor rotation: ON =
FWD. While the motor is rotating, a change of
F/R will start a deceleration, followed by a
change in direction.
OFF Selects the direction of motor rotation: OFF =
REV. While the motor is rotating, a change of F/
R will start a deceleration, followed by a change
in direction.
23 PID PID Disable ON Temporarily disables PID loop control. Inverter
output turns OFF as long as PID Enable is active
(A071=01).
OFF Has no effect on PID loop operation, which
operates normally if PID Enable is active
(A071=01).
