Miniature linear positioner series for lab automation and light payload industrial applications

For OEMS in the business of building small instruments who want to bring their product to market faster, the Parker LCR is a linear positioner family that provides the smallest form factor with easy to use flexibility unmatched by most competitive products. The ideal solution for OEM instrument manufacturers and laboratory instrument applications, the LCR Series is a complete solution offering users unmatched flexibility in a small footprint linear actuator. The LCR Series offers a complete screw- or belt-driven actuator, including motor and drive.

The fine lead screw offers higher resolution and higher thrust with lower motor torque. The high lead screw also provides users with a higher speed solution and screw drive positioning capabilities. As an alternative to the screw driven options there is the LCR belt drive which is perfect for high speed motion or long travel (up to 1m) applications. Pairing these drive technologies with the different bearing designs (square rail or glider bushing), now available from Micromech, the LCR offers a complete miniature linear positioner with a sealed body design.

The major features of the LCR are: 22, 30, and 45mm frame sizes, stepper or servo motor options, an integrated drive option, rugged square rail design or economical slider bushing design.  There is also an encoder feedback option, direct inline or parallel motor mounting options, cables connectors fitted for ease of installation and they are RoHS compliant (Restriction of Hazardous Substances Directive).

The positioners are ideal for OEM instrument manufacturers looking for significant ROI from an off-the-shelf yet tailor-made solution. This is a complete package which includes amplifier/drive (integrated drive option), motor, actuator, bearings, seals and limit sensors. For example the Ion Series stepper drive is an OEM-friendly miniature motion drive capable of up to 2 amps in a 25 x 25 x 85mm square package. The run current is adjustable via a potentiometer, it has auto standby adjustable current to reduce heat generation and power consumption and the stepper resolution is available to 3200 steps per rev. It is DIN rail mountable or mounts directly to the LCR Series linear positioners and importantly RoHS compliant.

Building on a proven life science track record with the MX80 and LP28 series, Parker developed an easy to use, high quality, ‘off the shelf’ linear actuator for payloads up to 100N at travel lengths up to 1m. This new LCR Series provides an un-rivalled set of product options ranging from drive technologies to bearing designs including:

  • 2 leadscrew-drive options
  • 2 belt-drive options
  • 22mm or 30mm profile widths
  • The longest travel lengths in the industry at this size: up to 1m
  • Stepper or servo motor options
  • Custom motor flange designs to quickly mount any motor
  • Flush mount NPN, PNP, normally open or normally closed limit sensors
  • Magnetically coupled stainless steel sealing strip
  • New ion drive for quick and easy connections to PLC or other motion controllers

‘Accurate, Dynamic, with User Friendly Flexibility’

The TMC429 is a miniaturised low cost, high performance, stepper motor controller for up to three motors.

The TMC429 integrates all real time critical tasks in reliable, dedicated hardware incorporating an integrated motion ramp profile generator as well as an adaptable microstep sequencer with microstep RAM table. Advanced stop- and reference switch handling allows for precise and fast referencing as well as on-the-fly position checking. Automatic motor current control gives high motor dynamics while saving energy and the interrupt output can generate precise position pulses.

The TMC429 connects to the recent coolStep™ drivers (TMC260, TMC262 and TMC389) via Step- & Direction signals (S/D) or to the classic TRINAMIC drivers TMC236, TMC239, TMC246 and TMC249 via SPI™. The communication with the host microcontroller is performed with an extra SPI™ interface. The host just needs to do high-level control tasks, e.g. giving the command: Drive motor 2 to position 1000. The TMC429 automatically calculates the motion ramp based on velocity and acceleration parameters.

The main features then are: this is a miniaturised low cost 3 axes motor controller, it is high-performance micro stepper, has SPI™ host interface with easy-to-use protocol, step/direction or SPI™ driver interface and on-the-fly alteration of position set point, velocity and acceleration. In addition different types of SPI™ stepper motor driver chips may by mixed within a single daisy chain and communication on demand minimizes traffic to the SPI™ stepper motor drivers chain. It allows read-out of driver status information (current motion parameters eg. position, velocity, acceleration) and programmable 6 bit micro step table with up to 64 entries for a quarter sine wave period (SPI mode).

‘Affordable Automation’

Servo applications can now get a high-performance boost

Now available from Micromech are the Parker’sCompax3 servo drives with EtherCAT which is an open, real-time, high-speed motion-bus network that operates over fast Ethernet at 100Mbit. This development is a fast-growing industrial network offering speeds faster than DeviceNet, ModbusTCP and Profibus.

Parker’s Compax3 servo drives now utilise EtherCAT as a controlled node and implement the standard CAN over EtherCAT DS402 object library. This standardised implementation improves the ability to work directly with third-party EtherCAT managing nodes on the market.

EtherCAT has been added to the whole Compax family. First the standard Compax3, which is a high performance servo controller with a power range from 1 to 110 kW and a whole selection of functions. Then there is the Compax3S that has a rated power of 1 up to 25 kW and can be installed in 300 mm control cabinets. Next is the Compax3M with a power range of 2 to 20 kW where there can be a cost reduction for multiaxis applications thus reducing cabling costs. Then finally the Compax3H that has a power range of 35 to 110 kW

This enhancement improves a wide range of applications from tube bending, to pharmaceutical automation, life science and packaging. Each have benefited from EtherCAT.
