INTRODUCTION

Super High-Precision Encoders and Optimum Control T

echnology (LQ Control) Lead to the Development of a Super High-Precision Rotary-Type Positioning System

Canon has now developed a compact, super high-precision laser rotary encoder using semiconductor laser and integrated a motor unit directly. The result is a new high-precision positioning control system. That obtains a sinusoidal wave with 81,000 periods per revolution from the laser rotary encoder and digitally divides it into 4096 parts. This achieves a resolution of 0.0039 angle-seconds. By connecting our system controller equipped with optimum control, higher precision can be attained in positioning.



FEATURES

  • By motor encoder and optimum control (LQ control), the unit achieves high steady speed, high resolution, high precision, and high stationary stability.
  • With the use of an encoder, unlike laser-based instruments, the wavelength is unaffected by temperature, air pressure, humidity, and other similar factors; hence, it is superior in environment resistance.
  • Canon has developed its own built-in type high precision laser encoders, enabling the system to be smaller yet more precise.
  • By connecting the unit with system controller SC- 01H/PC, the system can be made even smaller with lower costs.


APPLICATION EXAMPLE

Servo Track Writer When a HDD (Hard Disc Drive) is just assembled, its magnetic disc contains no standard data or information, so it is necessary to record track information (equivalent to the groves on compact discs) magnetically for each HDD.

Such HDDs, without any standards, require that the R/W head be forced to move to certain positions with high precision. Canon’s rotary positioners play a crucial role as they carry out this positioning of R/W head with high precision. factors; hence, it is superior in environment resistance.
