Picomotor Driver Module, Closed-Loop, 2 Channel
Model: 8743-CL
Product Series Overview
Closed-Loop Picomotor Motion ControllerThe 8743-CL 2-axis closed-loop intelligent motion controller/driver provides fine tuning, absolute positioning, compact and low cost solution for driving New Focus closed-loop Picomotors products. It is a single-box solution that can be manual controlled with the New Focus 8758 hand control pad or computer controlled via USB, RS-485, or Ethernet communication interfaces using Newport Motion Control Language (NMCL) command set. All three computer interfaces are well supported via Windows DLL, sample LabVIEW VIs, and intuitive graphical user interface (GUI) Windows application with device auto-discovery feature. Each model 8743-CL controller/driver has two 4-pin RJ-22 single output ports and two 15-pin D connector for the encoder signal that can be used with any single-channel closed loop Picomotor actuator at any given time.
2-Axis Closed-Loop Control
LabVIEW™ and Windows DLL Support
For greater flexibility and to program the controllers yourself, Window DLL and sample LabVIEW™ VIs are included.
Daisy-Chain Up to 31 Controllers
You can daisy-chain up to 31 controllers together with four channels each, so you can have a network of up to 124 standard Picomotor actuators. The 8745-PWR-CBL and 8745-RS485-CBL cables are used to daisy-chain power and communication, creating a network of Picomotor controllers. This allows you to connect one master controller to your PC and be able to communicate with the entire stack. Note that one power supply is required for every three controllers.
Integrated Controller and Driver Design
The 8743-CL is a single-box solution that provides both control of Closed-Loop Picomotor actuators as well as drives the actuators. For plug-and-play use without need for computer control, you can use the 8758 hand control pad. This image shows recommended compatible products for this controller.
USB and Ethernet Connectivity
The model 8743-CL controller/driver has two computer interface ports: USB-Device and Ethernet. This makes connecting and communicating with a host PC very simple. This controller also features an embedded HTTP server which generates a dynamic web page to accept command line input and show immediate response.
