2108 =" Auto-0" (Auto-run, default)

Drive in terminal mode

1103=0

The enable signal input (digital input 1) is configured to be

automatically recognised and is not required to be reasserted

following a trip or a power up in order to start the drive. If the

run input is closed prior to the mains power being applied to

the ACS250, and remains closed while the drive is powered

up, the ACS250 will start.

"Auto-0" is normally used where access to the enable input is

restricted and the drive needs to run as soon as mains power

is applied. It must only be used where this form of start up

presents no danger to personnel or equipment in the vicinity

of any moving or electrical parts.

Drive in keypad mode

1103=1 or 2

The enable signal input must always by present in order for

the drive to run. The drive will power up in a stop condition

and the start button on the keypad will control drive start.

Removal of the enable input will cause the drive to stop. While

the enable is present normal start/stop behavior is controlled

by the start and stop keys on the keypad.

2108="Auto-1", "Auto-2", "Auto-3", "Auto-4", "Auto-5"

In this mode, the operation is similar to "Auto-0", except

that the user can define how many times the drive will

automatically attempt to clear a trip and restart before

permanently tripping and requiring a manual reset. The drive

will make between 1 ("Auto-1") and 5 ("Auto-5") automatic

attempts to clear the trip and restart. Note that parameter

1100 (keypad mode restart function) must be set to 2 or 3.

The delay between restart attempts is set at 20 seconds.

The restart attempt counter (1-5) is reset by any of the

following operation.

– Powering the drive down and back up again.

– Pressing the reset (stop) button on the drive keypad when

the drive is tripped (displaying a trip message).

– Removing and reapplying the hardware enable signal.

1100 Keypad mode restart function

These values apply only when the drive is running in keypad

mode, 1103=1 or 2.

Minimum speed, keypad start

1100=0

The ACS250 will automatically run at the minimum

programmed frequency (value entered into parameter 2007)

when started from the keypad, regardless of the speed it was

previously running at prior to a stop or power off condition

being applied. With minimum speed (2007) set to 0 the drive

will always restart with a set point speed of 0.

Previous operating speed, keypad start

1100=1

The ACS250 will automatically run at the previous speed set

point, prior to the stop condition being applied, when started

from the keypad. This applies both to the drive being stopped

and to the mains input power being removed (previous set

point is retained on power off). E.g. with the drive powered

off while running at 20 Hz, the next start after power on will

cause the drive to run immediately up to 20 Hz.

Minimum speed, terminal start

1100=2

With this mode the ACS250 uses the enable input (digital

input 1) as the start/stop reference to the drive rather than the

buttons on the keypad. The behavior of the enable input in

defined by parameter 2108.

Once enabled the ACS250 will automatically run at the

minimum programmed frequency (value entered into

parameter 2007) when started from the keypad, regardless of

the speed it was previously running at prior to a stop or power

off condition being applied. With minimum speed (2007) set to

0 the drive will always restart with a set point speed of 0.

Previous operating speed, terminal start

1100=3

With this mode the ACS250 uses the enable input (digital

input 1) as the start/stop reference to the drive rather than the

buttons on the keypad. The behavior of the enable input in

defined by parameter 2108.

Once enabled the ACS250 will automatically run at the

previous speed set point, prior to the stop condition being

applied, when started from the keypad. This applies both

to the drive being stopped and to the mains input power

being removed (previous set point is retained on power off).

For example, with the drive powered off while running at 20

Hz, the next start after power on will cause the drive to run

immediately up to 20 Hz.
