Omron FZ5 Vision System Selection and Configuration Guide

Lens selection and optical calculation

The FZ5 system supports C-mount lenses and is suitable for sensors with 1/3 inch, 2/3 inch, and larger pixel sizes. Choosing the right lens can ensure clear imaging, minimal distortion, and a depth of field that meets detection requirements.

1. Standard C-mount lens (1/3 inch)

Focal length: 3.5mm to 100mm

Aperture: F1.4 to F35

Applicable cameras: FZ-S, FZ-SC series

2. High seismic C-mount lens (2/3 inch)

Focal length: 6mm to 100mm

Features: Suitable for vibration environments such as stamping and conveyor lines

Model example: 3Z4S-LE SV-0614H to SV-10028H

3. Specialized lens for small cameras (FZ-LES series)

Focal length: 3mm, 6mm, 16mm, 30mm

Aperture: F2.0 to F16

The maximum outer diameter is only 12mm, suitable for narrow spaces

4. Microscopic lens (VS-MC series)

Optical magnification: 0.03 × to 0.65 ×

Fixed aperture options: F2, F5.6, F8

Example of Depth of Field Calculation (40 μ m Diffuse Circle):

15mm lens, 0.03 x magnification, depth of field at F2 is 183.1mm

50mm lens, 0.48 x magnification, depth of field at F8 is 4.1mm

Suitable for precision measurement, wafer inspection, and electronic component positioning.

Engineering Tip:

When using extension tubes, it is not recommended to stack multiple extension tubes of 0.5mm, 1.0mm, and 2.0mm together, otherwise the threaded connection may become loose.

When the total length of the extended pipe exceeds 30mm, seismic reinforcement measures must be added.

Communication interface and network protocol

The FZ5 series supports multiple communication methods, making it easy to integrate with devices such as PLCs, robots, and upper computers.

1. EtherNet/IP

Supports 100Mbps (100Base TX)

Recommend using CAT5e and above STP cables

Official recommended cable brands: Hitachi Metal NETSTAR-C5E, Cangmao Electric KETH-SB, SWCC FAE-5004, etc

Attention: The shielding layer of EtherNet/IP cable is only grounded at one end to avoid ground current interference.

2. Serial communication

RS-232C/422A: 1 channel

Suitable for communication with old PLCs or instruments

3. USB interface

LCD integrated type: 4-channel (USB 1.1/2.0)

Box type controller: 2 channels

Supports mouse, USB flash drive, trackball

Attention: When using two USB drives at the same time, do not insert them into adjacent ports to avoid physical interference and malfunction.

4. Parallel I/O

Input: Up to 17 points (including RESET, STEP, encoder signal, etc.)

Output: Up to 29 points (including RUN, BUSY, GATE, OR, ERROR, STGOUT, etc.)

Support multi line random triggering mode, suitable for complex synchronous control.

Processing Items for Image Processing

The FZ5 system provides a wide range of image processing tools, covering the entire process of localization, recognition, measurement, filtering, calibration, and more.

1. Positioning and Search

Flexible Search: Adapt to Workpiece Deformation

Shape Search III: Resistance to environmental changes (individual differences, posture fluctuations, noise occlusion)

EC Circle Search: High precision circle detection

2. Measurement

Edge Position/Edge Pitch: Edge Detection Based on Color Changes

Circular Scan Edge Position: detects the center and radius of a circular workpiece

Gravity and Area: Extract color regions, calculate centroid and area

3. Identification

OCR+OCR User Dictionary: Character Recognition and Custom Dictionary

2D Code/Barcode: Supports Data Matrix, QR Code, Code 39, Code 128, etc

Character Inspect: Character Comparison Based on Model Dictionary

4. Image enhancement and conversion

Color Gray Filter: Convert color to grayscale and enhance specific colors

Anti Color Shading: Eliminating Uneven Background Colors

Polar Transformation: Polar coordinate transformation, suitable for circular printing character recognition

5. Data processing and process control

Parallelize: Parallel the measurement process to shorten the total time

Statistics: Calculate the average of multiple measurements

Unit Macro/Calculation: Custom Formulas and System Variable Operations

Installation and Environmental Standards

1. Power supply and grounding

Power supply voltage: 20.4-26.4 VDC

Special warning: It is strictly prohibited to ground the 24VDC positive pole of the Lite controller, otherwise touching the SG (0V) part (such as the controller housing or camera housing) may cause electric shock.

2. Working environment

Temperature: 0-50 ° C (standard), 0-45 ° C or 0-50 ° C depending on fan speed

Humidity: 35% to 85% (no condensation)

Storage temperature: -20 to 65 ° C

3. Weight and size

LCD integrated type: approximately 3.2kg (2 camera type) or 3.4kg (4 camera type)

Box type Lite controller: approximately 1.8kg

Installation hole: M3 depth 6mm, four installation holes

Common configuration errors and troubleshooting

Problem 1: The camera cannot recognize

Check if the cable length exceeds the supported range (especially for 5-megapixel cameras)

Confirm if the extension unit FZ-VSJ is powered (12VDC)

Confirm if the camera is correctly connected to the camera interface (1-4)

Problem 2: Image flicker or severe noise

Check if the power grounding is compliant (Lite controller positive pole must not be grounded)

Check if the cable is STP and if the shielding layer is grounded at one end
