Smart Ethernet drives add flexibility to motion systems
April 26th 2010 Smart drives offer economic and space-saving solutions for many common single-axis automation requirements. Baldor's new smart drives also feature an Ethernet interface compatible with the deterministic motion control networking standard, Powerlink.
Programming capability is now fitted without charge on all of Baldor's MicroFlex e100 and MotiFlex e100 single- and three-phase drive ranges. The versatile drives may be used to control rotary and linear servo motors, linear motors, closed-loop vector motors, and in V/Hz control modes.
The embedded Mint-language programming capability supports basic motion programming requirements including performing relative and absolute moves, S-ramp profiles, jog and homing movements, changing target positions on the fly, registration moves, and reacting to real-time trigger events. This allows standalone drives to provide solutions for common automation tasks such as cutting or feeding to length, indexing axes, simple pick and place motion, and machine adjustments such as changing guides or backstops to reconfigure machinery for new batches. More flexible PLC interfacing is another notable application.
If used in a Powerlink system, the local intelligence adds versatile new system building capabilities. Critical events can be acted on directly, eliminating the impact of network and controller scan time latencies; the faster response of critical axes can be translated directly into higher throughput. Another fundamental difference a smart drive can make is by using the local intelligence to offload a centralised Powerlink network controller.
