Operating instructions

74 Application manual Positioning 04/08
The operation mode is the result of the combination of 3 possible input signals and 3
status changes to produce the required output signal. The unit digit defines the
evaluation upon the start of the motion block, the tens digit defines the evaluation
as soon as the reference value is reached and the hundreds digit defines the evalua-
tion at the end of the motion block.

unchanged __0 _0_ 0__
On __1 _1_ 1__
Off __2 _2_ 2__
Note: The underscore characters "_" are used as wildcards so that it can be
seen directly for which place (unit, tens, hundreds digit) the value is
used.
Start
“Start” is evaluated when a positioning operation starts.
Reference value reached
The evaluation of "Reference value reached:" depends on the parameter con-
figuration for
Motion Mode 1208:
Motion Mode 1208
Evaluation of "Reference value reached":
0 - absolute
1 - relative
2 - Touch probe: rising edge
3 - Touch probe: falling edge
10 - Gearing, absolute
11 - Gearing, relative
12 - Gearing,
touch probe: rising edge
13 - Gearing,
touch probe: falling edge
20 - Gearing, direct sync., absolu-
te
21 - Gearing, direct sync., relative
22 - Gearing, direct sync., Touch-
Probe: Rising Edge
23 - Gearing, direct sync., Touch-
Probe: Falling Edge
Evaluation of "Reference value reached:" if
Target Position / Distance 1202 is reached.
4 - Velocity Evaluation of "Reference value reached:" if
Speed 1203 is reached.
14 - Gearing
24 - Gearing, direct synchronisati-
on
Evaluation of "Reference value reached:" when
master speed is reached and logic signal "57 –
In Gear" is set.
End
The evaluation of "End:" depends on the parameter configuration for
Operation
Mode
1221:
Operation mode 1221
Evaluation of "End":
Automatic sequence Evaluation of "End:" after completion of motion block.
Single motion
No evaluation of "End": The digital signal corresponds
to the status "Reference value reached:". The status
depends on the selected operation mode for the digi-
tal signal (parameter 1218, 1219, 1247, 1248). Possi-
ble statuses: "off", "on" or "unchanged".
