PIM2401, the new Technosoft intelligent plug-in minidrive, is specially designed for motion control applications where space is dramatically limited. Its miniature size (39x44x14 mm) and weight (15 g) allow it to be mounted horizontally or vertically, inside the machine or near the motor. The drive is manufactured with simple pins; this architecture reduces the time needed to assemble it. PIM2401 controls DC, brushless, linear and step motors up to 25 W (24 V, 1 A).

With its small dimensions, PIM2401 embeds a digital drive, a powerful motion controller and PLC functionalities in the same unit. One of the key advantages of PIM2401 is its ability to execute complex motions without requiring any external controller. Complex movement sequences can be programmed directly on the PIM, while system control functions are handled from the supervising PC or PLC. Motion modes as contouring, profiling, gearing, electronic camming, PVT are easily executed in stand-alone or multi-axis configurations.

A development platform for automotive and industrial motor-control applications built around a 32bit microcontroller is designed to simplify development of three-phase motor-control systems.

A pair of 8bit microcontrollers have low power consumption and high performance making them suitable for use in household appliances and digital audio/video equipment.

The URT hardware consists of a PXI chassis, an embedded PXI dual-core controller and the National Instruments PXI-5671 2.7 GHz RF vector signal generator. Optionally, the PXI-4461 data acquisition module and the PXI-5661 2.7 GHz RF vector signal analyzer with a digital downconverter can also be used for audio analysis or RF recording...

Designed to control and document critical parameters with dose uniformity and cascade impactor testing for dry powder inhalers is the the Critical Flow Controller TPK 2000 from Copley Scientific.

The National Instruments cRIO-9014 controller is based on the Freescale MPC5200 processor built on Power Architecture™ technology and the Wind River VxWorks real-time operating system (RTOS) to deliver the processing speed, memory and storage required for a variety of demanding embedded and industrial applications such as high-speed machine control, machine monitoring/protection, in-vehicle data logging, and embedded device prototyping.

The ArtDrive-S XVy-Evolution series high performance DSP based servodrives for precision motion control applications have been launched by Gefran.

Suited for applications utilizing ac and dc operated LVDT inputs, the microprocessor-based, dual-channel Series DMC provides digital position indication and cross-channel math and control functions for monitoring, measuring, and control requirements. Units offer programmable input averaging, digital filtering, and HI/LO limit detection. GUI enables operators to calibrate and set up sensors, retrieve or send programs, and view and collect data remotely through RS-232 or Ethernet.

Avago’s integrated ACPL-332J and -331J intelligent gate drivers improve precision motor inverters by featuring Active Miller Clamp, integrated Vce desaturation detection, under voltage lockout protection, built-in IGBT shut down, and isolated open collector fault feedback. Active Miller clamping eliminates the need for a negative gate drive, saving negative power supply and PCB space.
