OS³
Digital Drives
Series OS³:
is a family of Motors and Digital Drives, that are prefect for integration
with Series 10 or Power GP numerical controls. Our propriatary digital
bus, based on OS-Wire with its high specification (90 MHzes) is a brand
new concept enabling the Drives to operate as an integrated component
of the numerical control with assured flexibility and advanced performance.
OS3 drives can
be directly connected to the 3 phase supply network. They operate with
a nominal 400V to 480V AC power input. This characteristic allows the
product to be used in applications in a variety of geographical locations
without need for a transformer to adapt to the local power source. The
drives have an internal supply derived from the 3 phase to feed the control’s
electronics. This feature allows dynamic breaking in the event of interruption
of the power network. The control’s electronics are also supported
by an external 24v d.c. supply. During the dynamic breaking phase, energy
accumulated by the load is dissipated across internal breaking resistors.
For extremely heavy work cycles an external breaking resistor can be connected
in place of, or in parallel with the internal resistors. In common with
most drives, the high-tension bus is accessible through a connector, this
allows the use of external supplies containing breaking resistance. Various
motors with different technologies can be controlled, such as permanent
magnet motors, brush-less motors, induction motors and variable reluctance
motors. The standard transducer is a sinusoidal encoder (Sin-Cos). Programmable
inputs and outputs increase the drive’s flexibility. The OS3 family
of drives is available in 6 different power ranges beginning with the
minimum 3,5A nominal current (2,5Kw) up to 30A (21Kw). All versions utilise
the same internal control module.

DAC
DAM Servo Drives
The
integrated OSAI offer is completed by a line of digital drives and brushless
motors, which offers products with torque, speed and inertia values suitable
for any manufacturing needs. Digital vector control drives and their asynchronous
motors for multi-spindle control plus
a
standard digital connection and a powerful graphic setup tool for Windows™,
which simplifies the procedures for setting up and testing the system.The completely
digital DAM drives for controlling brushless motors are also available with
a SERCOS digital connection.
Sercos™
Digital Interface
In addition to the traditional analog input (+/- 10V) for controlling the speed
or torque, DAC drives provide a SERCOSä digital interface for communication
with the numeric control system by means of a high-speed optic fibre connection.
The digital interface ensures greater immunity to noise and a higher capacity
for real-time data exchange with the numeric control system.
The main benefits gained by the end user are enhanced accuracy in the finishing
of the machined part and epitomised machining times. The benefits gained by
the manufacturer are the reduced cost of cabling and easier procedure for setting
up and testing the machine.
The
DAC line includes digital drives and brushless motors for axis control.
The direct power supply DAC and DSC drives (400 V, three-phase) simplify
installation in electrical cabinets, thus reducing costs and saving space.
The completely digital DAM (Digital Axis Module) drives are also available
with a SERCOS digital connection with the numeric control, immunity to
noise and the considerable reduction in the cost of their cabling are
only a few of the advantages to be gained. The synchronous brushless motors,
with rare earth permanent magnets, in the DS series, designed
for a bus voltage of 540 Vdc, provide high powers with low current absorption,
a limited space requirement and dynamic features. |

Universal
Digital Controller
The universal digital control module is common to all the DAM and
DSC axis and spindle drives. The speed or torque commands may be received
via an analog input, RS-232 serial line or SERCOS interface. The built-in
position control may be based on a master encoder input or a preset position.
The powerful, built-in DSP, which controls the current loops and speeds
every 62.5 microseconds, ensures a constant regulation of the motor speed
independent of variations in load of the motor. The procedure required
to put the motors into operation is made easier by the setup software
for Windows, which provides a graphic display of the block diagram of
the regulating system and the preset values of the parameters. |
