04/08 Application manual Positioning 69
A motion block can be started with “Start Positioning” even if the “Holding Time” is
not elapsed.
Input signals for starting and stopping motion block sequences or single
motions
Start and Stop of the positioning:
1221
A positioning sequence or a single motion will be executed or stopped
according to the adjusted parameter .

Note: Before a positioning operation can be started, the point of reference of
the positioning operation must be identified in a homing operation.
Otherwise, error message "F1570 – No Homing Done" will be displayed
if you try to start a positioning operation.
Example:
In an application, the position in motion block 1 is approached first after activation.
Motion block 1 is set in
Starting-Record Number 1228. Then, the absolute target
positions 2, 3 and 4 are approached continuously according to the parameter con-
figuration. If the start signal is reset and started again, the sequence starts again
with motion block 1. If, however, the stop signal is received, the operation is
stopped as long as the stop signal is present.
