SKB1100110
Control Techniques Commander SK 1.1KW Inverter Drive 100...120V AC Single Phase 5.2A

The SKB1100110 is a 1.1kW 5.2A 100...120V AC variable frequency drive designed to control the speed of an AC motor.. Like all members of the Commander SK range, the Control Techniques SKB1100110 is incredibly easy to set-up, configure and install. Fortunately simplicity does not come at the expense of features and with onboard intelligence, I/O, Ethernet and Fieldbus communications options. Commander SK allows you to do far more than you would expect from a standard open loop 1.1kW AC drive. As an official Control Techniques Integration Partner, Northern Industrial are able to provide pre and post technical support as well as a wide array of option modules.

Performance and Reliability

Control Techniques has built its reputation for manufacturing quality, high performance AC inverter drives with industry-leading warranties and the SKB1100110 is no different. The Commander SK offers unique performance and functionality for a general purpose drive, while delivering greater efciency and energy savings. The Commander SK possesses advanced features like PID controller, output frequency up to 1500 Hz, brake control function, threshold detectors, variable selector, motorised pot, logic functions, time delay, and second motor map. Add the LogicStick for PLC functionality to the SKB1100110, plug in a Fieldbus or I/O Solution Module and you have a high-value, low cost 1.1kW drive with the power to perform.

Setting Up Your Commander SK

Setting up the SKB1100110 is simple thanks to the innovative CTSoft drive configuration tool, which is included free of charge with any new Commander SK. CTSoft is for the commissioning, optimising and monitoring of Control Techniques drives. This software enables you to:

• Commission the inverter using the configuration wizards
• Read, save and load drive configuration settings
• Remotely control the drive with simulated run, stop, reverse and jog push buttons
• Visualise and modify the configuration with live animated diagrams

Accessories & Option Modules for Commander SK Inverters

The SKB1100110 has a wealth of plug-in option modules designed to expand the functionality of the Commander SK AC drive. These include keypads, storage, communications modules, input/output modules and automation options.

Keypads and Storage

• SK-Keypad - This is a panel mounting LED display and keypad with a high IP65 rating
• SM-Keypad Plus - Plain text, multi-language LCD keypad
• HMI Panels - A range of fully configurable LCD touch screen display
• SmartStick - Inserting the SmartStick into the front facia of the drive enables parameters to be copied from one drive to another. This is especially useful for replacing a configuration across multiple drives

Automation

• LogicStick - Inserting the LogicStick into the front facia of the drive adds the required memory storage for use of the onboard PLC features. This is an advantage in applications where traditionally a small external PLC would normally be used

Communication Options

• SM-CANopen - The CANopen interface supports various profiles including several drive profiles
