NORD Drivesystems BU0200 - Manual (Page 12)

1 General information
BU 0200 GB-4411 Subject to technical alterations 11
1.1 Overview
This manual describes two very similar basic versions of the SK 200E product family.
Wherever the SK 2xxE is referred to, this concerns information which applies to all devices in this family.
If the information exclusively applies to the versions SK 205E / SK215E / SK225E / SK235E, this is apparent
from the designation SK 2x5E.
If the information only refers to the versions equipped with an integrated mains unit and integrated analog
inputs (SK 200E, SK210E, SK220E, SK230E), this is apparent from the designation SK 2x0E.
Functionalities
All models of the SK 2xxE series have the following functionalities:
Basic features of the SK 2xxE:

High starting torque and precise motor speed control setting with sensorless current vector control

Can be installed directly on, or near to the motor.

Permissible ambient temperature -25°C to 50°C (please refer to the technical data)

Integrated EMC mains filter for limit curve A Category C2 or C3 (not for 115V devices)

Automatic measurement of the stator resistance for precise determination of motor data

Programmable direct current braking

Integrated brake chopper for 4 quadrant operation, optional brake resistors (internal/external)

Temperature sensor input (TF+/TF-)

Evaluation of an incremental encoder possible via digital inputs

NORD System bus for connection of additional modules

Four separate online switchable parameter sets

8x DIP switches for minimal configuration

Diagnostic LEDs (SK 2x5E incl. signal statuses of DIs / DOs)

RS232/RS485 interface via RJ12 plug

Plug-in EEPROM data storage

Integrated PosiCon positioning control (Manual BU 0210)

CANopen absolute value encoder via the NORD System bus
Differences between the individual versions (SK 200E / SK 205E / … SK 235E) are summarised in the
following table and will be described in this manual.
