19.1.158.3 States of the sequencer
The internal state machine of the sequencer distinguishes the following five states:
[19-71] Internal state machine of the sequencer
Status Display
C01402
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.
