NUM LAUNCHES
ACTIVE VIBRATION
CONTROL SYSTEM
NUM has launched
an innovative
accelerometerbased
active
vibration control
system for CNC machine tools.
Primarily designed to improve
machining by virtually eliminating
tool head vibration, the system
further helps increase productivity
by maximising material removal rate
(MRR) and can also provide valuable
real-time feedback for predictive
maintenance purposes.
The system is available as a
retrofittable option for any machine
tool that uses NUM’s MDLUX high
performance digital servo drives,
which form part of the company’s
Flexium+ CNC platform.
NUM’s active vibration
control system is a very costeffective
solution that provides
unprecedented dynamic damping
capabilities. Most competitive
accelerometers on the market
are only capable of low frequency
sampling rates and require
additional signal conditioning
electronics before they can be
connected – usually via Fieldbus
– to the CNC or PLC system.
Typically, acceleration data can
only be retrieved once every 20
milliseconds, which is inadequate
for vibration damping purposes on
machine tools. The accelerometer in
NUM’s new system is sampled every

100 microseconds, which means
that it can be used for closed loop
control at bandwidths approaching
several hundreds of Hertz.
The small flange-mounting
accelerometer transducer can
easily be attached to the machine’s
tool head and has a sensitivity
of 0.02 g (1.96 m/sec/sec), with a
measurement range of plus/minus
2 g (plus/minus 19.6 m/sec/sec).
The transducer connects directly
to the digital servo drive, obviating
the need for any additional signal
conditioning circuitry.
The active vibration control system
utilises the drive embedded macros
(DEM-X) option that is available on
NUM’s MDLUX high performance
digital servo drives. This option
enables real-time macros to be
embedded within the drive in
order to manipulate its regulation
algorithms. The output signal from
the accelerometer transducer can
thus be used to directly influence
the behaviour of the speed servo
control loop. All MDLUX servo drive
modules use advanced DSP control
techniques to maximise the CNC
kernel-to-drive servo bus speed,
and feature high loop bandwidths
and special acceleration algorithms
for uncompromised speed and
positioning accuracy.
One of the most interesting
applications of NUM’s new active
