Motors and Drives
Another new product Lenze introduced at SPS/IPC/ Drives is the 3200C controller that combines PLC logic, motion control and visualisation in a single unit (Fig. 2). By bringing together the latest fast microprocessors with updated operating software, the 3200C delivers a tailored combination of hardware and software that can implement automation systems in a cost-effective way. Designed for centralised control systems, this new offering suits machines with single- and multi-axis drives, giving powerful control over a matching range of external drives and actuators. Lenze says the 3200C controller is designed to integrate
with the Lenze L-force I/O system 1000 to create a single control station with a fast 48 MHz backplane bus and a 1 μs time stamp. Up to 64 I/O modules can be combined with digital and analogue I/O, temperature measurement, counters and encoder evaluation.
To ensure that the hardware remains reliable in industrial environments the 3200C uses flash memory for storage instead of hard discs, and the Intel Atom processors operate without requiring a fan - hence there are no moving parts. In the event of a power supply failure, an integrated UPS (uninterruptible power supply) ensures that the retained variables of the controller are saved.
Onboard programming
A company well known for its ‘smart’ drives is Baldor Electric. And its Microflex e100 and Motiflex e100 single- and three-phase smart drives now benefit from new Mint Lite programming capability as well as being compatible with Ethernet Powerlink. These drives are available in a broad choice of power ratings up to 33.5 A, with higher ratings coming soon. The versatile drives may be used to control rotary and linear servo motors, linear motors and closed-loop vector motors. The embedded Mint Lite 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. The programming facility enables standalone drives to act as controllers in automation and machinery tasks such as cutting or feeding to length, indexing axes, simple pick-and-place tasks, and making machine adjustments such as changing guides or backstops. More flexible PLC interfacing is another notable feature.

Drive manufacturers offer a defined process data exchange interface with PLCs (the drive profile), and the ability to program Baldor’s drives means that the standard drive profile may be adapted, typically to simplify the communications process or to optimise the drive’s performance characteristics for a specific application. All of Baldor’s Microflex e100 and Motiflex e100 drives
come with built-in I/O as standard, plus Canopen manager capability to support distributed I/O expansion and HMI
Precision spur gear range enhanced P
recision gear manufacturer Ondrives Ltd’s precision spur gear range has been further enhanced with the addition of a number of different materials and cutting methods to offer the customer even more choice. Managing Director Andy Higgs says:
“We wanted to offer our customers’ more materials as we have found that applications these days are deeming what were once considered special materials to be more acceptable and the new product range has been designed with this in mind.” Cast iron GG25, titanium, Delrin POM (white) and Peek GF30 (light brown) are all now offered as standard. All of these materials are offered on the spur gears with

the cast iron, Peek and Delrin available on the precision worm gears.
Precision skive hobbed spur gears are also included within the range ensuring the quality grade and tooth finish are even more precise than standard where applications might call for this, states Managing Director Ben Hinchliffe. Many different modules and sizes are available within these ranges covering a wide variety of potential requirements and customers are assured of the quality given these are all made in-house by Ondrives in the UK. l
