Process sequence and signal states
INFORMATION
For the behavior of the drive at standstill, observe the information in the section "Stop functions" in the "Control functions" configuration menu of the inverter.

[2] | Drive synchronous | PI 9:1 |

[3] to [4] | Move to the start position | PO 9:1 PO 7/8 |

[4] | If the actual position lies within the configured window width, the feedback "In position" is issued. The drive stops subject to position control. | PI 1:7 |

Behavior when enable is withdrawn:
If the enable is withdrawn from the drive while the synchronous operation state is not equal to "STOPPED", the drive stops with the corresponding deceleration and the operating mode is canceled.
The drive must be moved back to the start position using the "Positioning absolute" operating mode (400) before the "Automatic – cut length control" operating mode (1400) can be started again.
If the enable is withdrawn from the drive while the synchronous operation state is "STOPPED", the drive is stopped. A new enable continues the movement. If the synchronization position has not yet been reached, the drive synchronizes again after the cut length has been reached. Otherwise, an error is reported.
Behavior when start is withdrawn:
If the start signal is withdrawn from the operating mode while the synchronous operation state is not equal to "STOPPED", the drive desynchronizes according to the configured desynchronization strategy and the operating mode is canceled.
The drive must be moved back to the start position using the "Positioning absolute" operating mode (400) before the "Automatic – cut length control" operating mode (1400) can be started again. If the start signal is withdrawn from the operating mode while the synchronous operation state is "STOPPED", the drive is stopped with the deceleration PO 4. When the start signal is present again, the operating mode is continued. If the target cut length has not yet been reached, the drive synchronizes again after the cut length has been reached. Otherwise, an error is reported.
