Smart drives provide servo dynamics and precision

Paired with AC Vector drives with smart control functionality, IE2 and IE3 standard asynchronous motors as well as permanent-magnet IE4 synchronous motors can deliver servo-level dynamics and agility.

With state-of-the-art frequency inverters used as either a motor-mount, wall-mount, or cabinet installation, NORD DRIVESYSTEMS can implement highly precise positioning tasks, safety applications, and sophisticated functions such as synchronization, coordinated multi-axis operation, winding control, and flying shear operations.

These systems are significantly more economic than conventional servo technology solutions due to lower costs and a much larger variety of available system components, including a versatile program that allows for a wide range of customized configurations. NORD frequency inverters feature a real-time microprocessor (cycle time 10 ms) and support free programming of drive-related functions according to IEC 61131 in order to relieve the workload of external PLCs.

200% overload capacity ensures high operating safety, specifically in crane and hoist applications. By using field-oriented control technology, these controllers perform consistently under flexible loads from near standstill all the way up to the motor’s rated speed, with or without an encoder. The drives can deliver high starting torques and speed feedback can also be provided. The SK 540E cabinet mounted frequency inverter integrates a universal encoder interface for SSI, BISS, EnDat profile 2.1, and Hiperface operation. NORD’s line-up of distributed inverter technology covers a performance range up to 22 kW, while cabinet devices range up to 160 kW. NORD Drivesystems provide full-scale mechatronic drives, manufacturing geared motors and electronic units and programming logic functions in-house.
