The control bit
sequence mode
decides between execution of one single motion block
(
sequence mode = 0
) and execution of a sequence of motion blocks (
= 1
).
In both cases the selection of the desired motion block (motion block number of single
motion block or start motion block number of motion block sequence) is done by cal-
culating the motion block number from
motion block select
with the rising edge of
start motion block
While the selected motion block or motion block sequence is processed
in progress
is set to 1.
Motion block in progress
remains 1 until the motion block pr
cessing is finished. When using a single motion block
motion block in progress
is set
to 0 with completion of the single motion block. Otherwise when using a motion block
sequence
motion block in progress
is set to 0 when reaching a next motion block se
ting of 0 (end of motion block) or -1 (error) -2 (stop and error) or -
error).
While processing a motion block sequence the actual processed motion block is di
s-
played by object 0x5FF0
active motion block
.
If motion block processing is interrupted by setting
start motion block
to 0 the axle
stops with the ramp defined by the actual motion block. T
block/motion block sequence can be restarted again by setting
resume
edge of
start motion block
.
If
resume
is set to 1 and there is no valid motion block available the motion block
defined by
motion block select
will be used. A valid motion block is
0x5FF1
motion block to resume
.
Motion block to resume
displays -
valid motion block or the last motion block/motion block sequence was not interrup
Target reached
is set by motion blocks with absolute or relative positioning when the
actual position reaches the
position window
.
In gear
is set when the function electronic gear is used and the gear is coupled.
Setting
Halt
to 1 interrupts an actual processed motion block. The axle is stopped with
the ramp defined by the actual motion block. When reaching velocity 0
is set to 1. The drive remains in state
operation enabled
. Resetting
Halt
to 0 restarts
processing of the interrupted motion block.
