Note: For controller release of the power component, wiring of the following
digital inputs is required:
STOA (terminal X210A.3) and STOB (terminal X210B.2).
In safety-oriented systems, the documentation "Safe Torque Off" shall
be complied with.
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.
4.4.5 Starting, stopping and resuming
The processing of a parameterized positioning sequence can be started and stopped
by 3 digital signals. The following table summarizes the control options. The signifi-
cant signal is marked bold.
Mode Start Stop Resume Description
Normal 1 0 0
The motion blocks are executed in the param-
eterized order.
Stop 1 1 0
As soon as the stop signal is present the drive
will be stopped with
Deceleration 1206. If the
stop signal is resetted the drive will proceed at
the cancelled position.
Cancel

X 0
As soon as the start signal is resetted the posi-
tioning sequence will be cancelled and the drive
will be stopped with Deceleration 1202. If the
start signal is set again the positioning starts
with the starting-record number.
Resume 1 0 1
If a positioning sequence is cancelled the resume
function allows the proceeding of the sequence
at the last position (instead of the starting-record
number). Therefore first set the resume signal
and then set the start signal.
