PS.27: Index mode
Bit Meaning Value Explanation
0
Continue of the
prole processing
0: no
Approach a position and wait for a new "start positioning" command.
Only after this occurs will the following block be completed (approach
the next position). This is necessary if the drive has to come to a
standstill at a position to, e.g., allow processing of a workpiece. The
signal "target window reached" is set. The signal to continue can come
from an external control that supervises the processing. It can also be
generated automatically by a "timer" integrated into the inverter soft-
ware. (Descriptions of the timers in the context of the "start positioning"
generation see example 4 in this chapter).
1: yes
Automatic start of the next positioning step (dened in PS.26) without a
new "start positioning" command being necessary (as in the drill head
example). The drive does not stop at the target, but drives across it with
the speed chosen as positioning speed in the following block (PS.25
of the following block). (Exception: if in PS.00 the setting of the prole
speed by PS.31 is selected, then the target is crossed with the speed
set in the current block in PS.25). The switching condition "target win-
dow reached" is not set since this is only an "intermediate target".
1...3 Position setting
0: ab-
solute
The position is given as an absolute value.
2: rela-
tive
The new position is set relative to the previous target position. The
direction (right or left of the old target position) is determined by the sign
of the new position setpoint PS.24.
6: rela-
tive to
PS.38
(F/R)
The new position is set relative to the previous target position. The di-
rection (right or left of the old target position) is determined via a digital
input (selectable via PS.38 or via input function "relative position F / R"
in parameters di.24...di.35). The sign of the position setpoint is disregar-
ded.
