Inputs
Identifier/data type
Information/possible settings
bStart
BOOL
Start/continue positioning program
• Display parameter: C04690/2
FALSETRUE The positioning program is started/continued.
• Counters and outputs are not automatically reset by this.
• A positioning program interrupted by bBreak is continued with
the sequence step.
• The started positioning program is processed until the end, even
if bStart is reset to FALSE.
bPause
BOOL
Interrupt the current step of the positioning program
• Display parameter: C04690/3
TRUE
• An active positioning is interrupted.
• The drive is stopped with the current profile deceleration.
• A deceleration override is taken into account.
• The sequence of an active timing element is stopped.
• A "Standby" action is not interrupted, i.e. the output
bEnableFollower remains TRUE.
FALSE
• The interrupted positioning is completed.
• The distance of the profile already covered is considered here.
• Positioning processes with final speeds are not continued if the
final speed cannot be reached anymore.
• The deceleration of the stopped timing element is continued with
the residual time.
bNextStep*
BOOL
From library V02.00.xx.xx
Cancel current step and go to next step
FALSETRUE The current positioning program step is cancelled immediately and
the positioning program is continued with the next step listed in the
sequence table.
bCancel
BOOL
Cancel the current step and jump to the step defined in C04504
• Display parameter: C04690/6
FALSETRUE The current step of the positioning program is cancelled immediate-
ly and the positioning program is continued with the step defined in
C04504.
bBreak
BOOL
Interrupt positioning program
• This input is intended for a linkage with drive-relevant status signals (e.g. for con-
troller inhibit or quick stop).
• If the interruption is cancelled again by a reset to FALSE, a new FALSE/TRUE edge
is required at bStart so that the positioning program can be continued with the
sequence step.
• Display parameter: C04690/4
FALSE Condition for the program start via bStart.
TRUE The active positioning program is interrupted.
• If positioning is active, the drive is braked to standstill with the
deceleration time for stop.
• The system block LS_Positioner is deactivated.
• The system block LS_Homing is deactivated.
• The setpoint followers are deactivated.
• The digital output signals keep their state.
