NORD releases drives for greater servo dynamics and precision

Standard asynchronous motors providing IE2 or IE3 efficiency, and
permanent magnet IE4 synchronous motors can deliver servo level dynamics and
agility when teamed with advanced inverter electronics for smart control
functionality.

Utilising state-of-the-art frequency inverters for motor mounting, wall mounting
or cabinet installation, German drive expert NORD Drivesystems implements
highly precise positioning tasks, safety applications, and sophisticated
functions such as synchronisation, coordinated multi-axis operation, winding
control, and flying shear.

Users can achieve cost benefits on these systems over conventional servo
technology solutions; additionally, the larger variety of available system
components including a very versatile gear program allows for a wide range of
custom-specific configurations.

NORD’s frequency inverters feature a real-time microprocessor with a cycle
time of 10 ms, and support free programming of drive-related functions
according to IEC 61131 to relieve the workload of external PLCs. An overload reserve
capacity of 200% ensures high operating safety, for instance, in crane and
hoist systems.

Employing field-oriented control technology, these controllers achieve
excellent consistency under flexible loads and from near standstill up to the
motor’s rated speed, even without an encoder. The drives provide high starting
torques, and speed feedback can also be implemented.

NORD’s top-of-the-range frequency inverter SK 540E from the control
cabinet line integrates a universal encoder interface for SSI, BISS, EnDat
profile 2.1, and Hiperface. NORD’s line-up of distributed inverter technology
covers the performance range up to 22 kW, while cabinet devices range up to 160
kW.

NORD Drivesystems provides full-scale mechatronic drives, manufacturing
geared motors and electronics units and programming logic functions in-house.
