2D 3D Automated Measuring Systems Motion / Illumination Controller CE Certificate

2D 3D Automatic Vision Measurement Machine Motion and Illumination Controller

Introduction

UWC-4000i is an independent controller using the second generation advanced UWC technology. It is a specialist controller for CNC video measuring machine and coordinates measuring machine. UWC-4000i is embedded with 4 axis motion control, 3 axis linear transducer counting, 10 terminal illumination control, joystick data collecting processing card and probe function, offering an SIC (System In Case) solution for the high-end CNC VMM and general CNC CMM.

Working Principle

Features

1. Full close-loop control in the hardware phase (PID close-loop control protocol with Velocity Feed Forward and dead-band control, the refresh frequency of the servo is 2.5KHz), real-time adjusting of the motor rpm based on the linear transducer position feedback, to ensure the locating process completed when the motion planning ends (within the appointed locating accuracy). A one-time fast locating is promised with all kind of transmission structure, and more efficient when rigidity is higher. This optimize time consuming and gain much high efficiency.

2. Multiple transmission structure are supported, such as linear drive, ball screw, synchronous belt, multi-polar belt, wire rope and steel belt, etc. The speed curve is planned by higher-order function, which ensures the stability. (Transmission structure with high backlash such as gearing is not supported)

3. 3 axis motors rpm is using direction + Pulse adjusting mode, eliminating the null drift of the analog voltage control. The machine is in full static status when the software is capturing the image, reducing the abbe error caused by single end driving of the transmission device, ensures the measuring accuracy.

4. 10 terminal 3200 levels adjustable constant current control connects to the LED directly, 8 terminal are used for surface light, 1 for the contour light and 1 for the co-axial light. It is the best replacement for the normal illumination controller which is large and unstable. If more section of surface light is needed please make reference to the illumination manual.

5. UWC-4000i is embedded with direct joystick interface, which eliminates the data lagging situation of the traditional USB joystick, and improve the operation performance of the programming, single piece measuring and the probe measuring process. Probe automatic searching, auto feedback, error protecting function eliminates the crashing risk, and reduce difficulty of the PC software programming.

6. There is no PCB inside the compatible joystick of the UWC4000i but only few wiring is required. So users can design the appearance and style. We will offer the main schematic and the parameters of the components. The emergency switch and speed adjusting knob are embedded.

7. The UWC-4000i uses only a single USB cable to connect the PC, and no need for the PCI slot. This makes the wiring much more easy and smart, and increase the stability.

8. MOF function(Measure on the fly), capturing the image during the stage moving process, which much reduce the time consuming of the measuring process, and increase efficiency.

9. The axis control is using direction + pulse output motion control mode, RS422 level output, able to connect to varies signal of DC servo / AC servo / intelligent motors (SMART motors, Coolmuscle motors from UWC). It is suitable for the motors with encoder feedback or step motors.

10. All the API function support the multi-lines programming, the executing time for a single API function is 3.2-3.8ms.

11. The motion control programming considers the 2D / 3D measuring features and the user operating, offering user friendly programming and operation interface.

12. UWC4000i-R and UWC4000i-S are optional for 3 axis linear transducer counting. The connectors are directly compatible to all the common brands of linear transducers, supporting single-ended and difference square wave signal.
