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.


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

Comprehensive Autotune

Inertia measurement and static autotune reduce startup time.


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.


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

High Performance

Open-loop vector control.

Keypad Options
Choose between no keypad, high visibility LED keypad or multi-language LCD keypad based on the system design and operating environment.

Drive Mounted Brake Resistor
Unidrive 6sizes 1 and 2 feature a drive mounted brake resistor option to reduce panel space requirements.
