7.12.4.16 Posi mode / stop positioning
A deactivation of the input occupied with the function "positioning /synchronous activation" concludes the po-
sitioning mode. A running positioning that was aborted by the deactivation cannot be resumed after switching
the input back on.
If the input remains activated, an active positioning can be interrupted by quick stopping, deactivation of the
control release, triggering of the „power off“ function or occurence of an error (e.g.: E.OC, E.OP, etc.).
After the drive is "ready for positioning" again, an interrupted positioning must be restarted with a "start posi-
tioning" command.
With parameter PS.00, one can select how the drive should behave after an error occurs (i.e., after interruption
of an active positioning):
PS.00: Posi / synchronous mode
Bit Meaning Value Explanation
5
Behaviour after
error
0: Start index
from PS.28 The target position (PS.24) from the start index block is approa-
ched with the first "start positioning" after the interruption.
32: last tar-
get position The target position that was positioned to when the interruption
occurred will be approached with the first "start positioning".
Note: a sequential positioning is aborted only if the error (the interruption) occurred during an active positioning.
If the drive is stopped on target (even if it is only an intermediate target of the sequential positioning) e.g. swit-
ching off the control release does not lead to an interruption of the sequential positioning.
An active positioning can also be interrupted by setting bit 11 in control word Sy.43 or Sy.50
(field 2048: „activate interruption“).
In contrast to a termination due to abnormal stopping, the ramps from the OP-parameters are used and started
S-curves are not interrupted in a termination initiated by the control word. The modulation remains on.
If bit 11 "termination" has again been deactivated in the control word, there are two possibililties for the drive
to continue:
PS.52: Automatically execution positioning after STOP
Value Explanation
0: off
The drive waits for a new "start positioning" command. The current position setpoint PS.24 is
inherited for the new positioning.
1: on
The drive automatically starts a new positioning on the target that was approached at the time
of the termination by the control word. A change of the position setpoint PS.24 is ignored during
the "abort" bit is set.
7.12.4.17 Analog position setting
By means of the analog parameter setting, the parameter PS.24 "index / position" can also be adjusted. (For
more detailed information on the analog parameter setting, see chapter 7.15.9 and for the adaption of the ana-
log channels, see chapter 7.15).
To set a position setpoint in PS.24 "index / position" by analog input, the following adjustments have to be made:
●
Select the index in PS.23, where the set position should be written
●
Select PS.24 as the target for the analog parameter setting An.54: Analog para. setting / target =
1318h (bus address PS.24)
●
Select in An.53 which analog channel shall preset the set position
