10.3.9 Clamping system: Diagnostic statistics
This window displays the statistics for clamping operations and speed violations.
Statistical data Meaning
Number of correct clamping cycles Accumulated number of correct clamping cycles with or without
tool.
Correct clamping cycle means: "Released" clamping state [3] →
"Clamped" clamping state [7, 8 or 10] → "Released" clamping
state [3]. A clamping cycle is considered to be correct when a
clamping and subsequent release operation are performed via
the appropriate clamping states (without "State return"). Starting
from one clamping state, the next clamping state that can be
reached must not be the previous state. There is no dependency
on time.
Clamping time (without tool) The time within a clamping operation between the clamping
states "Tool released" and "Clamped without tool".
● Within tolerance
Accumulated number of clamping operations without tool that
were within the specified time.
● Outside tolerance
Accumulated number of clamping operations without tool that
were outside the specified time.
● Specification
Factory specification of the time for the clamping operation with‐
out tool.
● Current
Measured time for the last performed clamping operation with‐
out tool.
Clamped (without tool) Diagnostics during the "Clamped without tool" clamping state.
● Speed violations
Accumulated number of events during which the spindle speed
was greater than the set limit as delivered.
● Speed threshold
Limit for the spindle speed in the "Clamped without tool" clamp‐
ing state (as-delivered value).
Changing this speed limit via the diagnostics overview "S1
clamping system" → "Speed limits" → "Change" has no effect on
the value specified here.
Faulty clamping/releasing opera‐
tions (total)
Accumulated number of clamping operations that have not run
through the clamping states "Released" clamping state [3] →
"Clamped" clamping state [7, 8 or 10] → "Released" clamping
state [3] without interruption.
A clamping cycle is considered to be faulty when, starting from
one state, the next state that is reached is the previous state
again ("State return").
