954 SmartServo FlexLine
The balance test results in several quality indicators that can be viewed
in Engauge and partly on the SmartView.
Entity name Entity name (SmartView) Description
[Balance test result
unbalance]
[Drum unbalance [kg]]
(Product level)
The drum unbalance should be within 3
grams. When the drum unbalance is more,
check for contamination of the drum. If the
unbalance is still more than 3 grams replace
the drum bearings (refer to section 9.1.2).
[Balance test result
average weight]
[Avg meas weight [kg]]
(Product level)
Refer to section 9.1.2 when the displacer’s
weight differs more than 3 g from the value in
entity [Displacer weight].
[Balance test result
maximum weight]
[Max unbal weight [kg]]
(Product level)
[Balance test result
minimum weight]
[Min unbal weight [kg]]
(Product level)
[Balance test result
average frequency]
[Avg meas freq [kg]]
(Product level)
[Measured bearing
status]
- Refer to section 9.1.1
The result of the balance test can also be viewed graphically by the
diagram viewer in Engauge (Servo Unbalance Diagram).
Figure 9-1 Example of a smooth servo unbalance diagram (16 points)
Figure 9-1 shows an example of a balance test diagram of 16 points.
The blue line shows the actual unbalance table in [Hz], while the red
lines show the measured hysteresis.
