1.1
NORDAC SK 1000E Servo Controller
The NORD dynamic intelligence
The NORDAC SK 1000E is the best choice where rapid acceleration, fast movement and high
standstill moment, coupled with high speed and positioning precision, are essential. Combined with
the integrated PLC, technical functions and CANopen field bus connection, it is the solution for
demanding drive problems.
Rated current:
3.5-20Aeff, 3 AC380-460V 50-60Hz
Speed range:
Servo controller with re/- 22500 rpm,
Servo controller with incremental encoder is proportionally resolution
dependent, e.g. at 4096 increments +/- 18500 rpm (
Attention
: note the limit
frequency of the encoder, this is often only 250 kHz! )
NORDAC SK 1000E servo controllers are designed using fully digital signal processor technology
(DSP) with field bus connections for torque, speed and positioning regulation of synchronous and
asynchronous motors.
The field-orientated control concept with current, speed, position control and speed profile depiction in
just 50µs sampling time means that this system has extremely high dynamics and full motor
movement even when at standstill. Extremely high, load-independent speed and positioning accuracy
is achieved by the rotor position feedback. Demanding drive tasks can therefore be resolved.
Implemented technical functions underline customer benefits.
An integrated PLC rounds off the function spectrum of this controller.
The controller is commissioned with the operating software running under Windows 95/95, 2000, NT
and XP. Commissioning is facilitated by the supplied motor/controller database, oscilloscope and
numerous test functions, while the assistant means that anyone can commission the controller.
Some specifications are currently in preparation. Technical developments means that this product
description continuously undergoes changes and these changes are collected and the product description
is updated with the latest developments as and when necessary.

All servo controllers can operate synchronous and asynchronous motors. During commissioning, the
connected motor data record simply has to be loaded from the database.
