0011, CONTINUE_EXTERNAL: Behavior such as "CONTINUE_ON-THE-FLY";
however, an immediate block change can be triggered
by a 0/1 edge, up to the braking point. The 0/1 edge
can be connected to parameter r2526.2 of the
"position control" function module, via the binector
input p2633 with p2632 = 1, or via the measuring input
p2661 with p2632 = 0. Position detection via the
measuring input can be used as an accurate starting
position for relative positioning. If no external block
change is triggered, a block change occurs at the
braking point.
0100,
CONTINUE_EXTERNAL_WAIT:
An on-the-fly change can be triggered in the next
request during the entire motion phase via the control
signal "External block change". If "External block
change" is not triggered, the axis remains in the
parameterized target position until the signal is issued.
CONTINUE_EXTERNAL differs in that an on-the-fly
change is executed at the braking point if no "External
block change" was triggered, while there is a wait for
the signal here in the target position.
0101,
CONTINUE_EXTERNAL_ALARM:
The behavior is the same as for
CONTINUE_EXTERNAL_WAIT, but warning A07463
"External traversing block change in traversing block x
not requested" is output if an "external block change"
has not been triggered before standstill is reached.
The alarm can be converted to an alarm with a stop
response so that block processing can be aborted if
the control signal is not issued.
cccc: Positioning mode
With the POSITION task (p2621 = 1), this defines how the position specified in the
traversing block is to be approached.
0000, ABSOLUTE: The position specified in p2617 is approached
0001, RELATIVE: The axis is traveled along by the value in p2617.
0010, ABS_POS: Only for rotary axes with modulo offset! The position
specified in p2617 is approached in a positive
direction.
0011, ABS_NEG: Only for rotary axes with modulo offset! The position
specified in p2617 is approached in a negative
direction.
● Task parameter (command-dependent significance) (p2622[0...63])
Intermediate stop and canceling traversing block
The intermediate stop is activated by a 0 signal at p2640. After activation, the system brakes
with the parameterized deceleration value (p2620 or p2645).
The current traversing task can be canceled by a 0 signal at p2641. After activation, the
system brakes with the maximum deceleration (p2573).
The "intermediate stop" and "cancel traversing task" functions are only effective in the
modes "traversing blocks" and "direct setpoint input/MDI".
