CLK_B Start NC record from program B or quit fault
(like CLK_A, but for program B)
CLK_A Start NC record from program A or quit fault
With a rising edge at this input:
 the NC record number at the RECBIT... inputs will be accepted by the SPC200
for program A and processed. This will be indicated with the signal ACK_A
(see Fig.5/8).
an active fault is acknowledged if at the
same time a 1−signal is active at the
STOP input.
STOP Stop positioning task
An 0−signal at this input causes:
 the axes to be stopped (controlled stop).
 Depending on the parameterisation:
 The position at the time of the stop signal becomes the setpoint position
(default). After standstill, the axis runs back to this
p
osition.

from OS 4.93
(default)
.
After
standstill
,
the
axis
runs
back
to
this
position
.
 The current position at standstill becomes the setpoint position.
This function is only available as from firmware version 4.93 in combina
tion with WinPISA as from version 4.51.
The positioning task can be started again by:
a 1−signal at this input
 renewed starting of the positioning task via the relevant CLK input
(CLK_A/CLK_B).
Continuation
of a positioning task after a Stop signal is not supported in this
operating mode. If you use NC command G91, movement must be made to an
absolute position (G90) after each stop.
