PIline™ M-661 and M-662 Open-Loop Stages
M-661.4P0 and M-662.4P0 are the open-loop models. They achieve velocities to 800 mm/s and, due to the lack of the position encoder, are smaller than the closed-loop models. The M-662.4P0 has a square footprint and can be mounted in an XY configuration. The M-661.4P0 is intended for single-axis use only and is even smaller. Both stages are driven by a small external driver (included) that converts the control into ultrasonic oscillations for the piezo motor. Control is either external or through a manual pad (included) providing two operating modes: stepping mode and continuous motion.
External control is achieved through a PWM drive signal of 12 V. The distance traveled by the stage corresponds to thewidth of the pulse. The smallest step is on the order of 0.1 Ám and corresponds to a 10 Ás input pulse (shorter pulses are not recognized). By varying the length of the input-active period, the step length and thus the velocity can be controlled.
Complete Package with Driver, Power Supply and Cables
All M-661, M-662 and M-663 PIline™ translation stages come complete with driver, power supply and cables, facilitating setup and operation. OEM drivers and motors are available as well.
PIline™ M-665.2PM Closed-Loop 50 mm Stage
A larger footprint (114 x 114 mm) closed-loop translation stage with 50 mm travel is also available. Request our separate datasheet.
* For using NI controllers, please request further info on the C-809 motion interfaces (see link). For using GALIL cotrollers, the M-663K005 option is required.
Advantages of PIline™ Linear Piezo Motor Drives
The linear stage M-661.4P0 (right side in the front) uses the ultra-compact piezo motor P-661.4P0, which is available as an separate OEM product. The standard driver electronics C-862.PMD (right side in the back) can also be used with these OEM P-661 instead of the OEM electronics (left side in the back).

Did you know that PI also makes the world's smallest rotary piezo motors? C-171 rotary piezo motor, match for size comparison. The C-171 is currently the world's smallest commercially available rotary piezo motor. It measures only 3 mm in diameter and provides velocity to 1000 rev/min and torque of 0.4 mNm.
