Process sequence and signal states

INFORMATION

For the behavior of the drive in idle state, observe the information for the "Stop functions" in the "Functions" > "Monitoring functions" > "Control functions" configuration menu of the inverter.

Signal states

[1]

General enable

  • PO 1:0 = "1"
  • Enable/emergency stop

PO 1:0

  • "1": Enable
  • "0": Deceleration with emergency stop ramp
  • PO 1:1 = "1"
  • Enable/application stop

PO 1:1

  • "1": Enable
  • "0": Deceleration according to application limit

[1]

Selection of operating modes

"Cut mark control"

PO 6

1402 (decimal)

[1] to [3]

Start of the axis

PO 1:7
PO 18/19
PI 2
DI 04

  • "1": The drive waits until the cut mark has been detected and then synchronizes with the master signal in a position-dependent way.
  • "0": The drive desynchronizes. The master distance is specified by PO 18/19.

[1] to [5]

ACTIVE
Master-based mode active

PI 9:0

  • "1": The synchronous operation status of PI 9 (HighByte) is not "STOPPED".
  • "0": The synchronous operation status of PI 9 (HighByte) is "STOPPED".

[2]

Mark sensor signal
Signal evaluation
"Pulling a gap"

PO 9:2

  • "1": Pull a gap at the current mark.
  • "0": Do not pull a gap at the current mark.

[3]

Drive is synchronous

PI 9:1

  • "1": The synchronous operation status of PI 9 (HighByte) is "ACTIVE".
  • "0": The synchronous operation status of PI 9 (HighByte) is not "ACTIVE".

[5]

Pulling a gap finished

PI 9:2

  • "1": Pulling a gap is finished and the drive begins the movement to the start position.

[4] to [6]

Move to start position

PO 9:1
PO 7/8

  • "1": The drive moves back to the start position specified via PO 7/8. If pulling a gap is active, a gap is pulled beforehand.
  • INFORMATION: The signal is not evaluated if the synchronous operation status is PI 9 (HighByte) = "GEAR-IN".

[6]

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

  • "1": "In position" message active.
Behavior when enable is withdrawn:

If the enable is withdrawn from the drive while the synchronous operation status is not equal to "STOPPED", the drive stops with the corresponding deceleration and the operating mode is canceled.

If the enable is withdrawn from the drive while the synchronous operation status is "STOPPED", the drive is stopped. A new enable continues the movement. If the synchronization position has not yet been reached after the cut mark sensor has been detected again, the drive synchronizes again after the cutting length has been reached. Otherwise, an error is reported.

The drive must be moved back to the start position using the "Positioning absolute" operating mode (400) or via the "Travel to start position" bit before the "Automatic – cut mark control" operating mode (1402) can be started again.

Behavior when start is withdrawn:

If the start signal is withdrawn from the operating mode while the synchronous operation status is not equal to "STOPPED", the drive desynchronizes according to the configured desynchronization strategy and the operating mode is canceled.

If the start signal is withdrawn from the operating mode while the synchronous operation status 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 cutting length has not yet been reached, the drive synchronizes again after the cutting length has been reached. Otherwise, an error is reported.

The drive must be moved back to the start position using the "Positioning absolute" operating mode (400) before the "Automatic – cut mark control" operating mode (1402) can be started again.
