PMSD401–PMSD404 Controller for Piezo LEGS® Precision Stages

Built to move innovation forward.

From optical alignment to analytical instrumentation, compact closed-loop control helps precision stages become complete positioning systems.

ALIGN

Control optical and laser alignment motion.

POSITION

Command repeatable stage positions from a host system.

MAP

Support scanning and measurement sequences.

HOLD

Move to position, then use the stage’s mechanical hold.

PMSD401–PMSD404. Control matched to the required axis count.

Typical applications

High-accuracy optical-system positioning
Laser alignment and beam positioning
Precision mapping and measurement
X-ray, analytical and measuring equipment
Microscope specimen positioning
Move-and-hold applications requiring a stable fixed position

Why it fits move-and-hold systems

The controller and Piezo LEGS® stage combination is particularly relevant where the application moves to a defined point and then remains static. The stage can maintain its mechanically held position without continuous motor power, helping to limit stationary-state heat generation around sensitive optical or measurement components.

Host control concept

The intended user experience is command-based control from a host computer. The host sends motion and status commands to the controller, the controller drives the stage, and the optical encoder closes the position loop. Final protocol, connector, command-set and interface documentation must follow the approved PiezoMotor controller design.

How to configure this controller

Count the controlled stage axes in the intended system.
Confirm every stage motor and encoder combination.
Confirm the required stage-cable quantity and length.
Confirm the approved host interface and command documentation.
Define power accessories and request the complete configured quotation.

Find your fit.

Select PMSD401 for one controlled axis, PMSD402 for two, PMSD403 for up to three or PMSD404 for up to four controlled axes.

PiezoMotor model	Reference source model	Controlled axes	Typical stage pairing

Stage and accessory integration

CKS-20: 2 m stage cable; included quantity per controlled axis remains to be confirmed
CKS-xx: stage cable naming in which xx represents length in decimetres; orderable lengths to be defined
CK-USB-RS: USB-to-RS485 conversion cable; driver installation procedure remains open
Regional AC cable and power responsibility remain to be defined
