Controller for Piezo motor stage｜THK PRECISION CO.,LTD.

Controller for Piezo motor stage

This product is a controller intended to drive and control an Piezo motor stage. In the controller, a control circuit and a driver are structurally integrated. If a piezo motor stage is connected to the controller, it can perform closed control using an optical linear encoder with an ABZ-phase output. The user can easily operate the controller by transmitting a control command from the computer via LAN, RS485, USB or RS232C interface.

Features

Space-saving with a slim body
Generates less heat itself
A type with a vacuum environment, a non magnetic type
High positional repeatability with a built-in liner encoder

Application

High-accuracy positioning of an optical system
Laser alignment
Precision mapping measurement
X-ray/analysis and measuring equipment
Specimen stage for microscopes
Application in which the object is to be held static after position adjustment

The product is very effective in applications where fixed-point positioning is mainly required or applications where the object is held static as the product is turned off after positioning.

This product is a controller intended to drive and control an LS-type piezo motor stage.
In the controller, a control circuit and a driver are structurally integrated. If a piezo motor stage is connected to the controller, it can perform closed control using an optical linear encoder with an ABZ-phase output.
Based on a controller for two-axis stages and a controller for four-axis stages, controllers for controlling one to four axes are offered.
The user can easily operate the controller by transmitting a control command from the computer via a LAN or an RS485 interface. The interface can be changed to an RS232C interface.

Features

It contains a control board, a driver board and a linear sensor interpolator. Being chain-connected via RS485 inside,the controller also supports multi-axis application (depending on the linear sensor).
Once the controller for controlling one, two, three or four axes is connected to the corresponding stage, it can immediately perform high-resolution positioning control.
The drive control is achieved with a linear sensor having a resolution of 10 nm and a driver having a drive resolution of 1 nm or below.
Since the drive resolution is 1 nm or below, the controller can also adapt to more accurate linear sensor other than the standard sensor.
Since the internal control board is chain-connected via RS485, the controller also supports multi-axis application (127 axes at a maximum).
