Low inertia motors drive motion control
Baldor has launched a new range of brushless servo motors for precision motion control applications, based on rare-earth neodymium iron boron magnets.
With the controller's combination of servo and stepper control capability for instance, it could implement a standalone X-Y-Z axis positioning solution - supported by four stepper axes and I/O for material handling and machine control.
Moreover, if the module is used with Baldor drives, it is capable of controlling up to seven precision servo motor axes.
Known as NextMove ESB, the motion controller is programmable using the popular Mint motion language or C.

Baldor has launched a complete range of IEC frame motors meeting the new 'Efficiency 1' standard, backed by a stocking service from the company's new European support hub in Bristol.
Motion control programming is multi-tasking
Baldor has launched a new version of its Mint system development environment to support the evolving needs of machinery and automation OEMs.
Motors ideal for machine tools and automation
Baldor has launched a range of AC vector-duty motors constructed using steel band techniques, for automation applications requiring very precise control of speed and torque.
Among the target applications are high speed printing, packaging, labeling and machine tools, and common process automation needs including positioning stages, robotics and rotary knives.
Based on an advanced Texas Instruments DSP core, NextMove ESB delivers exceptional real-time performance.
It supports servo loop closure times of 100 microseconds on three axes, with six-term closed loop control for accurate positioning (PID, velocity, acceleration feed forward, and velocity feedback).
The four stepper axes provide pulse and direction outputs at up to 500 kHz.
Onboard I/O completes the capability, allowing users to employ the module for machine control as well as motion - potentially eliminating the need for a separate controller such as a PLC.
The I/O comprises 20 digital inputs, 11 digital outputs, two 12-bit differential analog inputs and a precision 12-bit output, a CANopen-compatible fieldbus port, and two serial ports including a 12 Mbits/sec USB interface.
The high speed USB interface provides automation OEMs who build machines with PC hosts or user interfaces with new opportunities for enhancing the ruggedness of their equipment, and simplifying manufacture, by allowing the motion control subsystem to be panel mounted in the optimal location inside the machine - instead of in a PC expansion slot.
The module's integral Mint language capability provides flexible Basic-style programming for automation builders that allows application software to be developed and tested in a few hours.
Mint provides ready-to-use keywords for many common motion tasks from simple profiles to advanced movements such as software cams and flying shears.
These pre-written functions can substantially reduce time to market.
The latest MintMT version of the language supplied with NextMove ESB additionally includes a multi-tasking kernel.
This further simplifies development cycles, allowing complex machine control requirements to be divided into smaller tasks such as motion, man-machine interfacing, and I/O handling.
The software is royalty free, helping OEMs to reduce costs for equipment designs.
'Open architecture' facilities built into Mint, together with the use of field programmable FPGA logic, add another dimension to performance, as they allow move types to be adapted to suit individual applications.
This gives substantial flexibility to OEMs, effectively allowing users to configure a custom multi-axis motion controller for the price of a standard product.
Users seeking ultimate speed of execution may alternatively program the card using Texas Instruments' C compiler and Baldor's free library of C-compatible Mint functions for motion, I/O, communications, networking, operator interfaces, etc Firmware may then be embedded in the controller, or called as required from a host such as a PC.
