Item # 2049, A-341 PIglide HGS Hybrid Gantry Systems
Hybrid guide design with air bearings and recirculating ball bearing guides for high precision with low profile.
Hybrid design: Gantry axis with recirculating ball bearing guides, bridge axis with air bearing
Absolute encoder
High-performance ironless linear motors
Various travel ranges. Options and customized adaptations
Flexible modular platform
The A-341 PIglide HGS hybrid gantry system was developed for applications that require overhead motion and long travel ranges.
The A-341 hybrid gantry has a unique hybrid guide design. The bridge axis is equipped with a friction-free guide with air bearings that allow exact control of velocity as well as outstanding repeatability and straightness. The guide with air bearings considerably reduces particle emission over the workspace. The gantry axis is equipped with recirculating ball bearing guides on both sides for robustness and precision in limited installation space.
This combination of different guide technologies means that the A-341 hybrid gantry is ideally suited to applications that are based on the step-and-scan principle and at the same time, require a compact design.
The A-341 is coupled with industry-leading controllers and drive modules from ACS that offer superior servo performance, advanced control algorithms to improve dynamic performance and error compensation, and a wide suite of software development tools.
PIMag® magnetic direct drive
3-phase magnetic direct drives do not use mechanical components in the drivetrain, they transmit the drive force to the motion platform directly and without friction. The drives reach high velocities and accelerations. Ironless motors are particularly suitable for positioning tasks with the highest demands on precision because there is no undesirable interaction with the permanent magnets. This allows smooth running even at the lowest velocities and at the same time, there is no vibration at high velocities. Nonlinearity in control behavior is avoided and any position can be controlled easily. The drive force can be set freely.
Application fields
Scanning, Digital printing, Electronics assembly and inspection, AOI (Automatic Optical Inspection), Automation.
Absolute encoder
Absolute encoders supply explicit position information that enables immediate determination of the position. This means that referencing is not required during switch-on, which increases efficiency and safety during operation.
