– aaaa: Identifiers
000x → hide/show block (x = 0: show, x = 1: hide)
A hidden block cannot be selected binary-coded via binector inputs p2625 to p2630.
An alarm is output if you attempt to do so.
– bbbb: Continuation condition
0000, END: 0/1 edge at p2631
0001, CONTINUE_WITH_STOP:
The exact position parameterized in the block is approached (brake to standstill and
positioning window monitoring) before block processing can continue.
0010, CONTINUE_ON_THE_FLY:
The system switches to the next traversing block "on the fly" when the braking point
for the current block is reached (if the direction needs to be changed, this does not
occur until the drive stops within the positioning window).
0011, CONTINUE_EXTERNAL:
Same as "CONTINUE_ON_THE_FLY", except that an immediate block change can be
triggered up to the braking point by a 0/1 edge. The 0/1 edge can be triggered via
binector input p2633 when p2632 = 1 or via the measuring probe input p2661, which
is connected to parameter r2526.2 of the "position control" function module, when
p2632 = 0. Position detection via the measuring input can be used as an accurate
starting position for relative positioning. If an external block change is not triggered, a
block change is triggered at the braking point.
0100, CONTINUE_EXTERNAL_WAIT
Control signal "External block change" can be used to trigger a flying changeover to
the next task at any time during the traversing phase. If "External block change" is not
triggered, the axis remains in the parameterized target position until the signal is
issued. The difference here is that with CONTINUE_EXTERNAL, a flying changeover
is carried out at the braking point if "External block change" has not been triggered,
while here the drive waits for the signal in the target position.
0101, CONTINUE_EXTERNAL_ALARM
This is the same as CONTINUE_EXTERNAL_WAIT, except that alarm A07463
"External traversing block change in traversing block x not requested" is output when
"External block change" is not triggered by the time the drive comes to a standstill.
The alarm can be converted to a fault with a stop response so that block processing
can be canceled if the control signal is not issued.
– cccc: Positioning mode
The POSITION task (p2621 = 1) defines how the position specified in the traversing
task is to be approached.
0000, ABSOLUTE:
The position specified in p2617 is approached.
0001, RELATIVE:
The axis is traversed along the value specified in p2617
0010, ABS_POS:
For rotary axes with modulo offset only. The position specified in p2617 is approached
in a positive direction.
0011, ABS_NEG:
For rotary axes with modulo offset only. The position specified in p2617 is approached
in a negative direction.
