13

USP

Unattended Start

ON

On powerup, the inverter will not resume a Run

 

 

Protection

 

command (mostly used in the US)

 

 

 

 

 

 

 

 

OFF

On powerup, the inverter will resume a RUN

 

 

 

 

command that was active before power loss

 

 

 

 

 

14

CS

Commercial Power

ON

OFF-to-ON transition signals the inverter that the

 

 

Source

 

motor is already running at powerup (via bypass),

 

 

 

 

thus suppressing the inverter’s motor output in Run

 

 

 

 

Mode

 

 

 

 

 

 

 

 

OFF

ON-to-OFF transition signals the inverter to apply a

 

 

 

 

time delay (B003), frequency match its output to

 

 

 

 

existing motor speed, and resume normal Run Mode

 

 

 

 

operation

 

 

 

 

 

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/

ON

If A005=00, terminal [OI] is enabled for input.

 

 

current Select

 

If A005=01, terminal [O2] is enabled for input.

 

 

 

 

(Use terminal [L] for signal return.)

 

 

 

 

 

 

 

 

OFF

Terminal [O] is enabled for voltage input

 

 

 

 

(Use terminal [L] for signal return)

 

 

 

 

 

17

SET3

Set (select) 3rd motor

ON

The inverter uses 3rd motor parameters for generating

 

 

data

 

frequency output to motor

 

 

 

 

 

 

 

 

OFF

The inverter uses 1st (main) motor parameters for

 

 

 

 

generating frequency output to motor

 

 

 

 

 

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

 

 

 

 

 

20

STA

START

ON

Starts the motor rotation

 

 

(3-wire interface)

 

 

 

 

OFF

No change to present motor status

 

 

 

 

 

 

 

 

21

STP

STOP

ON

Stops the motor rotation

 

 

(3-wire interface)

 

 

 

 

OFF

No change to present motor status

 

 

 

 

 

 

 

 

22

F/R

FWD, REV

ON

Selects the direction of motor rotation: ON = FWD.

 

 

(3-wire interface)

 

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=1).

 

 

 

 

 

 

 

 

OFF

Has no effect on PID loop operation, which operates

 

 

 

 

normally if PID Enable is active (A071 = 1).
