Configured drive packages save costs
A configured drives service allows engineers to choose a base drive package and then enhance it with numerous options in line with the needs of the application.
Diagnosis and maintenance of machine tools
Rockwell Automation has introduced the QC10 ballbar which gives maintenance technicians a tool for assessing the dynamic motion and positioning precision of machine tools and production machinery.
Optimised Performance and Functionality.
PowerFlex 40 uses sensorless vector control for powerful motor torque at low speeds, making it ideal for applications such as incline conveyors, extruders and constant torque pumps.
The PowerFlex 40 is also equipped with highly configurable I/O including the ability to perform basic logic, timer and counter functions.
Performing these functions at the drive instead of a micro controller reduces both wiring and hardware costs.
In addition, the drive can perform many advanced functions such as PID and flying start, making it one of the most versatile products in its class.
Simplified Installation and Configuration.
To simplify programming, the PowerFlex 40 has an integral keypad with the 10 most commonly programmed parameters grouped together for fast and easy start up.
If PC programming is preferred, the drive's integral RS485 communications can be used along with Allen-Bradley DriveExplorer and DriveExecutive configuration and monitoring software.
Advanced Networking Capability.
The PowerFlex 40 is also designed to accommodate internally mounted communication option cards, such as DeviceNet, making it an ideal choice for applications requiring advanced networking capability.
Features such as Automatic Device Replacement (ADR) ensure a minimum of downtime in the event of a system failure.
The PowerFlex 40 features both DIN rail and panel mounting options for ease of installation.
Overall panel space can be reduced using the drive's Zero Stacking capability, which allows drives to be mounted side by side.
When complying with electromagnetic compatibility (EMC) requirements, the integral filter for single phase drives and piggy back mounted external filters for three phase ratings, further reduce the amount of panel space required.
Like all products within the PowerFlex family of drives, the PowerFlex 40 is designed to meet worldwide power ratings and packaging requirements for out-of-the-box performance.
The PowerFlex family of AC drives offers significant commonality across multiple platforms, including networks, operator interface, programming and hardware.
This commonality is designed to help users feel comfortable with the programming and start-up features available with any PowerFlex AC drive. Request a free brochure from Rockwell Automation Anorad ...
