DS 205.3 ; DS403.4
Application in:
All types of machines and installations up to a drive power of 1kW.
Especially as
4Q- servo drives in feed axes, for highly dynamic acceleration and braking applications,
for large control ranges,
for high efficiency,
for small motor dimensions,
for an even and smooth travel.
For speed and torque regulation or combined speed and torque regulation with or without a
superimposed position controller.
Constant drives for hoisting equipment, spindle drives, pumps, transverse and longitudinal
slitting drives, multi-motor parallel drives. Synchro –servo drives are compacter than other
electrical drives.
For use in:
Insertion machines, testing machines, sheet-metal working machines, machine tools,
machines for the plastics industry, automatic assembly machines, knitting and sewing
machines, textile machines, grinding machines,
wood and stone working machines, metal working machines, XY tables, machines for the
food industry, robot and handling systems, rack feeders, extruders, calenders and
also in many other machines and installations
The motors are:
designed for protection standard IP 65,
compact, for harsh environments,
for a high dynamic overload, maintenance-free
Note:
Braking operation for EC - drives
For example.: Un-reeling machines, hoists, flyweights. The braking energy is dissipated in
the regenerative circuit or fed back to the mains via an external inverter.
Caution:
The internal regenerative resistors have only a small continuous rating.
Calculate the retarding power and use external regenerative circuit discharge
resistors if necessary or for design safety. Calculation of regenerative power. See
page 24.
