bPause

BOOL

Interrupt the current step of the positioning program

TRUE

• An active positioning is interrupted.

• The drive is stopped with the current profile deceleration.

• A deceleration override is considered.

• The sequence of an active timing element is stopped.

• An action of "

Standby

" type is not interrupted.

FALSE

• The interrupted positioning is completed.

• The distance of the profile already covered is considered here.

• Positionings with final speed are not continued when the final

speed cannot be reached anymore.

• The sequence of the stopped timing element is continued with

the remaining time.

bNextStep

BOOL

Cancel the current step and go to the next step

FALSETRUE The current step of the positioning program is cancelled

immediately and the positioning program is continued with the next

step in the sequence table.

bCancel

BOOL

Cancel the current step and go to the step defined in

C01404

FALSETRUE The current step of the positioning program is cancelled

immediately and the positioning program is continued wit the step

defined in

C01404

.

bBreak

BOOL

Interrupt positioning program

• This input is intended for being connected to drive-relevant status signals (e.g. for

controller inhibit or quick stop).

• If the interruption is deactivated again by a reset to FALSE, a new FALSE/TRUE

edge is required at bStart in order that the positioning program is continued with

the sequence step.

FALSE Condition for program start via bStart.

TRUE The active positioning program is interrupted.

• If a positioning is active, the drive is brought to a standstill with

the delay time for stop (

C01251/1

).

• The MCK operating modes

Speed follower

,

Homing

,

Positioning

and

Position follower

are deactivated.

• The digital output signals keep their states.

bReset

BOOL

Reset positioning program.

• Also possible with interrupted positioning program.

FALSETRUE The positioning program is reset.

• If a positioning is active, the drive is brought to a standstill with

the delay time for stop (

C01251/1

) without considering an

acceleration override.

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

• The digital output signals, counters and timing elements are

reset.

• If the "

Stand-by

" action is active, it is cancelled.

wStartStep

WORD

Step of the sequence table the positioning program is to start with.

0 Positioning program starts with step 1 of the sequence table.

1 ... 100 First step

Others Positioning program does not start.

not assigned Positioning program starts with step 1 of the sequence table.
