Commander SK 

A simple drive to solve the widest range of applications

Commander SK simplifies the installation and configuration of the drive to save time, yet has the performance and depth of functions required to solve more complex applications challenges than other drives in its class. Key features include:

Easy to maintain

Optional Smartstick parameter copy device allows drive settings to be stored, backed-up and easily re-loaded without requiring a PC.

Expandable 

SM Option Modules for fieldbus and Ethernet connectivity, real-time-clock and additional I/O

Flexible

Minimize inventory through single- or three-phase operation with 200V drives and dual fan/pump and machinery duty ratings on higher power modules

Feature packed

Onboard serial port with Modbus RTU for connecting to other automation equipment or PC tools for access to advanced features

Intelligent 

Add programmable logic control with the optional plug in Logicstick memory device.

High Performance

Open-loop vector control
