ctrlX SAFETY "SafeMotion"
WARNING
Personal injury or property damage caused by insuffi-
cient overrun distance of the axis!
Before starting to check the Safe maximum speed, make
sure that the braking ability and the overrun distance
are sufficient. If this is not the case, the test cannot be
carried out. If necessary, adjust the velocity threshold for
this axis.
First of all, call the oscilloscope function via the link in the dialog. When the
oscilloscope is started, the measuring signals already are automatically config-
ured.
● Trigger: S-0-0390, Diagnostic message number on F7020
●
Measuring signals:
–
S-0-0390, Diagnostic message number
–
P‑0‑3238, SMO: Active velocity threshold
– P‑0‑3258, SMO: Actual velocity value
After the configuration, the oscilloscope has to be activated via the “Start”
button. Afterwards, move the axis in such a way that the threshold of the
"Safe maximum speed" is exceeded and the error "F7020 Safe maximum speed"
is generated. With the corresponding oscilloscope measurement, the check can
be accordingly documented.
In normal operation, the threshold of the "Safe maximum speed" is displayed in
the recorded parameter “P-0-3238, SMO: Active velocity threshold.
Checking the velocity threshold for Safe standstill
The "velocity threshold for Safe standstill" is active in all operating states. It can
be checked in each operating status in which the axis can be moved.
First of all, call the oscilloscope function via the link in the dialog. When the
oscilloscope is started, the measuring signals already are automatically config-
ured.
● Trigger: P‑0‑3256, SMO: Encoder evaluation status, bit 6="1"
● Measuring signals:
–
S-0-0390, Diagnostic message number
–
P‑0‑3256, SMO: Encoder evaluation status
–
P‑0‑3258, SMO: Actual velocity value
After the configuration, the oscilloscope has to be activated via the “Start”
button. Afterwards, the axis has to be decelerated from a velocity greater than
the "velocity threshold for Safe standstill". With the corresponding oscilloscope
measurement, the check can be accordingly documented.
At the point in time when the measurement is triggered, Safe Motion has
safely detected the axis standstill and acknowledges this in the parameter
“P-0-3256.0.0, SMO: Encoder evaluation status", bit 6 Via the recorded param-
eter “P-0-3258.0.0, SMO: Actual velocity value", the exact velocity can be deter-
mined below which SafeMotion safely detects the axis standstill.
