Sequencer control functions

The following functions serve to control the sequencer.

Select sequence

A sequence is selected in a binary-coded fashion via the triggers assigned to the four functions "Select sequence (bit 0)" ... " Select sequence (bit 3)" in compliance with the following truth table:

Select sequence				Selection
Bit 3 0x2631:053 (P400.53)	Bit 2 0x2631:052 (P400.52)	Bit 1 0x2631:051 (P400.51)	Bit 0 0x2631:050 (P400.50)	Selection
FALSE	FALSE	FALSE	FALSE	No sequence selected
FALSE	FALSE	FALSE	TRUE	Sequence 1
FALSE	FALSE	TRUE	FALSE	Sequence 2
FALSE	FALSE	TRUE	TRUE	Sequence 3
FALSE	TRUE	FALSE	FALSE	Sequence 4
FALSE	TRUE	FALSE	TRUE	Sequence 5
FALSE	TRUE	TRUE	FALSE	Sequence 6
FALSE	TRUE	TRUE	TRUE	Sequence 7
TRUE	FALSE	FALSE	FALSE	Sequence 8
TRUE	FALSE	FALSE	TRUE	Invalid selection
...
TRUE	TRUE	TRUE	TRUE

Start sequence

The selected sequence is not started automatically. For starting the sequence, two functions are available:

–

0x2631:030 (P400.30): Run/abort sequence (status-controlled start)

–

0x2631:031 (P400.31): Start sequence (edge-controlled start)

Further control functions

The following functions serve to control the started sequence:

–

0x2631:032 (P400.32): Next sequence step

–

0x2631:033 (P400.33): Pause sequence

–

0x2631:034 (P400.34): Suspend sequence

–

0x2631:035 (P400.35): Stop sequence

–

0x2631:036 (P400.36): Abort sequence

For controlling the sequencer via the network, the sequencer control functions can also be assigned to the NetWordIN1 data word 0x4008:001 (P590.01).

Parameter

Address	Name / setting range / [default setting]		Information
0x2631:030 (P400.30)	Function list: Run/abort sequence (Function list: Seq: Run/abort) – Setting can only be changed if the inverter is disabled. – From version 03.00 – Further possible settings: Trigger list		Assignment of a trigger for the "Run/abort sequence" function. Trigger = TRUE: Start selected sequence. Trigger = FALSE: Abort sequence. Notes: – The assigned trigger must remain set to TRUE for the duration of the sequence. – If the trigger bit is reset to FALSE, the sequence is aborted. In this case, the standard setpoint or the setpoint source selected via setpoint change-over is active again. – A sequence is selected in a binary-coded fashion via the trigger assigned to the four functions "Select sequence (bit 0)" 0x2631:050 (P400.50) ... "Select sequence (bit 3)" 0x2631:053 (P400.53). – For an edge-controlled start, the function "Start sequence" 0x2631:031 (P400.31) is optionally available.
0x2631:030 (P400.30)	0	Not connected	No trigger assigned (trigger is constantly FALSE).
0x2631:031 (P400.31)	Function list: Start sequence (Function list: Seq: Start) – Setting can only be changed if the inverter is disabled. – From version 03.00 – Further possible settings: Trigger list		Assignment of a trigger for the "Start sequence" function. Trigger = FALSE ↗ TRUE (edge): Start selected sequence. Trigger = TRUE ↘ FALSE (edge): No action. Notes: – After the start, the sequencer remains activated until the function "Stop sequence" 0x2631:035 (P400.35) or the function "Abort sequence" 0x2631:036 (P400.36) is executed. A normal stop command does not reset the start command for the sequencer. – For a status-controlled start, the function "Run/abort sequence" 0x2631:030 (P400.30) is optionally available.
0x2631:031 (P400.31)	0	Not connected	No trigger assigned (trigger is constantly FALSE).

Trigger = FALSE ↗ TRUE (edge): Next sequence step. Trigger = TRUE ↘ FALSE (edge): No action. Notes: – The execution of the current step is completed even if the time parameterised for the segment has not elapsed yet. – The function is only relevant for Sequencer mode 0x4025 (P800.00) = "Step operation [2]" or "Time & step operation [3]". – A jump to the next sequence step is not possible if the sequence pauses, the sequence is suspended or the final segment is executed.

0x2631:034 (P400.34)	Function list: Suspend sequence (Function list: Seq: Suspense) – Setting can only be changed if the inverter is disabled. – From version 03.00 – Further possible settings: Trigger list		Assignment of a trigger for the "Suspend sequence" function. Trigger = TRUE: Suspend sequence. Trigger = FALSE: Continue sequence. Notes: – This function serves to temporarily change over to the standard setpoint or the setpoint source selected via setpoint change-over. – The sequence is continued at the point where it was suspended.

Trigger = FALSE ↗ TRUE (edge): Stop sequence. Trigger = TRUE ↘ FALSE (edge): No action. Notes: – If the sequence is stopped, it is jumped to the final segment. – The further execution depends on the selected End of sequence mode 0x402F (P824.00).

0x2631:036 (P400.36)	Function list: Abort sequence (Function list: Seq: Abort) – Setting can only be changed if the inverter is disabled. – From version 03.00 – Further possible settings: Trigger list		Assignment of a trigger for the "Abort sequence" function. Trigger = FALSE ↗ TRUE (edge): Abort sequence. Trigger = TRUE ↘ FALSE (edge): No action. Notes: – This function serves to directly stop the sequence without the final segment being executed.

Example for operating mode

In the following example, the digital inputs 2 and 3 are used for controlling the sequencer.

–

The analog input 1 is set as standard setpoint source.

–

Switch S1 starts the motor in the forward direction of rotation. Switch S1 in initial position stops the motor again.

–

The button S2 starts the sequence, the button S3 cancels the sequence. After the abortion, the normal setpoint control is active again.

The status signals can be assigned to digital outputs. Configure digital outputs

①	If the inverter is enabled and no error is active, the motor can be started with the "Start" function. As the sequence has not been started yet, first the normal setpoint control is active.
②	The "Start sequence" function is used to start the selected sequence in an edge-controlled way.
③	Sequencer mode 0x4025 (P800.00) = "Time operation [1]": The switch-over to the next step of the sequence is made after the time set for the current segment has elapsed.
④	The segment 2 is configured here in such a way that the relay will be triggered during the time of processing.
⑤	End of sequence mode 0x402F (P824.00) = "Keep running [0]": After the sequence has been processed, the setpoint set for the end segment is continuously transmitted to the motor control until the sequence is cancelled.
⑥	In case of the end segment, the time setting determines the delay after which the configured output states are to become active. Here, the end segment is configured in such a way that the digital output 1 is set after 10 s have expired.
⑦	If the "Run" function is set to FALSE, the motor is stopped with the stop method set in 0x2838:003 (P203.03). The started sequence, however, remains active and the sequencer-controlled outputs keep their state.
⑧	Start of sequence mode 0x4040 (P820.00) = "Restart sequencer [0]": If the "Run" function is set to TRUE again, the (still active) sequence is restarted.
⑨	The "Abort sequence" function is used to cancel the sequence in an edge-controlled way. In this case, the standard setpoint or the setpoint source selected via setpoint change-over is active again.
