8 Monitoring
8.3.3 List of alarms
112*
Standstill monitoring
Cause: Incorrect position control direction
-
Mechanically clamped axis has been pushed out of position.
-
Fault on control device
(actuator), at
the
tacho,
motor,
in the
mechanics or NC measuring circuit hardware
-
On standstill
-
On clamping
-
On deceleration
Interlocking of NC START
-
Setpoint zero
-
Servo enable is removed in MD 156 after delay has elapsed (servo
enable relays drop
out)
-
Follow-up mode
The following error could
not
be cleared faster than the time entered MD
156.
Scan:
Effect:
Explanation:
On clamping the limit defined in MD
212*
was exceeded.
MD 212* (clamping tolerance) must be
greater
than MD 204*
(exact
stop limit coarse)
MD 156 (switch-off delay
control enable)
must
be large enough
to
allow the following error of the axis entered
to
be cleared within the
period entered.
Remedy:

*
Contour monitoring
Scan:
When machining in AUTOMATIC, but
not
--
when accelerating
--
when decelerating
--
at
speeds lower than that in NC MD 336*
(contour speed)
-
Interlocking of NC START
-
Setpoint 0
-
The
control enable is removed after the time stored in MD 156
has elapsed
(control enable relay drops out)
Follow-up operation
-
The tolerance band NC MD 332' was exceeded
at
a speed
greater
than MD 336*
When accelerating or decelerating the axis has
not
reached the new
speed within the time defined by the Kv
factor
-
Increase
the tolerance band in NC MD 332*
-
Check the KV factor
-
Check the optimization of the speed controller
-
Check drive
actuator
