Impact/meaning

Ready

0

When there is no interruption by bBreak, the program can be started.

RUN

1

The program is processed.

Break

2

The program is paused and the traversing of a profile is stopped.

• The outputs keep their states

• An active positioning is interrupted.

• The drive is stopped with the current profile deceleration.

• A acceleration override is not considered.

• After deactivating the break, the positioning program and a previously active

positioning are continued at the same position.

Break

3

The traversing of a profile is cancelled.

• The drive with the delay time for stop (

C01251/1

) is brought to a standstill.

• The digital output signals keep their states.

• After the interruption has been deactivated (bBreak = FALSE), another start signal

is required to continue the program with the sequence step.

Reset

4

The program is reset.

• An active positioning is cancelled.

• The drive with the delay time for stop (

C01251/1

) is brought to a standstill.

• A acceleration override is not considered.

• The program flow is cancelled ("program end").

• The digital output signals and the counter are reset.

• If a standby operation is active, it will be cancelled.
