Working Principle M-661 and M-662 stages have a new, patented, ultrasonic drive developed by PI. The highly compact, integrated P-661 piezomotor drive can provide accelerations of up to 20 g and velocities of 500 mm/s and more, together with high resolution and holding force. Because the ceramic stator is pressed against a slider of the stage, piezomotors resist motion with an intrinsic holding force when the stage is at rest. The result is very high position stability without the heat dissipation common with conventional linear motors. Furthermore, there are no gears, leadscrews or other mechanical components to contribute play or backlash. M-661 / M-662 Fast and Compact Both models are operated without position feedback, where they can achieve speeds of up to 500 mm/s. The square footprint of the M-662.470 makes it suitable for XY-configurations, while the M-661.370, which is even smaller, is designed for single-axis systems. Drive Electronics for Open-Loop Operation Two different driver electronics solutions are available for PILine® open-loop stages and OEM motors. They can either be operated by a simple pulsed-mode driver (C-181), or by a more sophisticated version which allows controlling the speed with an analog signal in the ±10 V range (C-185). C-181, C-170 – Pulsed Mode Operation Pulsed operation is especially suited for applications requiring small steps or rapid end-to-end motion, as in microscopy, automation or similar applications. The motor can be controlled with 5 V TTL pulses connected to the signal input on the driver electronics. The width of the pulses will determine the approximate length of the steps the motor makes. The smallest possible step is about 50 nm, requiring a pulse of about 10 µs in duration. The pulse rate and width can be used to influence the step size and rate, thus determining the velocity. A flexible, programmable pulse generator with integrated C-181 driver is available as C-170.161. C-185 Analog Driver The C-185 analog driver controls the motor speed as a function of a ±10 V analog input. With an external position sensor and a controller, it is thus possible to set up a very fast, closed-loop system. The M-663 stage with integrated linear encoder (see p. see page) can also be run with this driver. Accessories For the operation of PILine® stages and piezo linear motors, a drive electronics is required. The driver is necessary to create the ultrasonic oscillations of the piezoceramic actuator of the motor. The choice of the drive electronics depends on the application and the motion controller used and is therefore not part of delivery of a PILine® stage or motor. The unit with the drive electronics, however, must be ordered at the same time as the stage, so that they can be tuned for optimum performance with each other. Biotechnology Micromanipulation Microscopy Quality Control Semiconductor Test Equipment Shutters High-Speed-Scanning R&D Photonics Packaging PILine® M-662 (left side) and M-661 stages are the smallest piezo-motor-driven translation stages available on the market that achieve speeds of up to 500 mm/s.
