1.1 Overview
This manual describes two very similar basic versions of the SK 200E product family (NORDAC FLEX).
Wherever the
SK 2xxE
is mentioned below, this refers to information that applies to all devices in this
family.
If the information applies exclusively to versions SK 205E/SK 215E/SK 225E/SK 235E, this is
apparent from the designation
SK 2x5E
.
If the information only applies to versions SK 200E/SK 210E/SK 220E/SK 230E, this is recognizable
from the designation
SK 2x0E
.
Basic properties
• High starting torque and precise motor speed control setting by means of sensorless current vector
control
• Can be installed directly on, or close to the motor.
• Permissible ambient temperature -25°C to 50°C (please refer to the technical data)
• Integrated EMC line filter for limit curve class A/category C2 or C3 (not with 115 V devices)
• Automatic measurement of the stator resistance and determination of precise motor data
• Programmable direct current braking
• Built-in brake chopper for 4-quadrant operation, optional braking resistors (internal/external)
• Separate temperature sensor input (TF+/TF-)
• Evaluation of an incremental encoder via digital inputs possible
• NORD system bus for linking modular additional modules
• Four separate parameter sets that can be changed over online
• 8x DIP switches for minimal configuration
• LEDs for diagnosis (SK 2x5E incl. DI/DO signal statuses)
• RS232/485 interface via RJ12 plug
• Plug-in data memory (EEPROM)
• Integrated "POSICON" positioning control (

• CANopen absolute value encoder evaluation via the NORD system bus
• Operation of
three-phase current as ynchronous m otors
(ASM) and
P ermanent- M agnet
S
ynchronous
M
otors
(PMSM)
• Integrated PLC (

Differences between the individual versions (SK 200E/SK 205E/… SK 235E) are summarized in the
following table and will be described in this manual.
