With seven selectable travel ranges from 25mm to 300mm, commercial or precision grade positioning options and a choice of integrated or separate stepper motor/drive combinations, the H series actuator features a modular and smart design that provides a flexible mounting system for XY, XYZ and Gantry systems as well as telescopically arranged linear axes for extended Z-axis travel.
The H series actuator design is based on an extruded profile housing with T-slots that facilitate multi-axis actuator mounting, optional limit switches and customer fixtures. A fixed cover plate provides additional protection and is arranged to allow unrestricted carriage travel. The carriage, which may be moving or fixed, is supported by a sturdy linear guide bearing for maximum rigidity and a choice of commercial or precision grade leadscrews are available to suit application performance and budget.
A flexible coupling and anti-backlash nut arrangement guarantees high stiffness with repeatability stated at 0.2 microns for the commercial grade option and 0.1 microns for the precision grade version.
Extremely compact multi-axis configuration is possible using Heason Technology's recommended DSMS series stepper motors which have integrated microstepping drives for much reduced system wiring. With up to 51,200 steps/rev the maximum positioning resolution is 2 microns with traverse speeds to 170 mm/sec. Separate motor and microstepping drive combinations are available which can include through shafts for rear mounted manual knobs – or stages may be fully manually driven.
Heason Technology can provide fully customised systems based on the H series using its in-house design service. Bespoke options may include encoders for position verification or servomotor driven systems, alternative pitch leadscrews or ballscrews, and chain type cable management.
Motion controllers suited to the H series include Baldor’s NextMove-ESB-2 panel mount motion controller. With up to 4 axes of stepper or servo control, digital and analogue I/O, memory and optional HMI interfacing, the controller features the widely used MINT™ multitasking BASIC programming - or may be programmed with embedded ‘C’ or ActiveX components for host controlled applications. The ESB-2 includes simple-to-advanced motion control from point-to-point axis moves to interpolated compound moves that are synchronised with I/O events or external encoders. The controller can work as a stand-alone machine controller or with PLCs and other PC based machine control systems.
