Definition |
| Ai Technology |
The patented technology used to control a DC motor with external commutation over a standard M8 4-pin connector |
| Brushless DC Motor |
A D.C. motor with a permanent magnet rotor and coils in the stator. The stator coil currents are sequenced by an external brushless D.C. motor controller. In such motors, current and torque, voltage and rpm are linearly related. The main advantage to this type of motor is the elimination of EMI caused by the arcing brushes and improved motor life |
| ConveyLinx |
Conveyor controls architecture based upon modular distributed devices connected via Ethernet network |
| CC-Link IEF Basic |
Industrial Ethernet-based open high-speed and large-capacity network integrating distributed control, I/O control, safety control, and motion control for Mitsubishi PLCs. |
| DHCP |
Dynamic Host Configuration Protocol A protocol for assigning IP addresses to devices on a network from a pool of available IP’s. A dynamic IP address changes each time the device connects to the network |
| EasyRoll+ |
Dynamic Host Configuration Protocol A protocol for assigning IP addresses to devices on a network from a pool of available IP’s. A dynamic IP address changes each time the device connects to the network |
| Ethernet-IP |
Industrial network protocol that uses Ethernet packets to adapt the Common Industrial Protocol (CIP) for use in industrial automation and control networks. The standard is maintained and supported by ODVA |
| Hall Effect Sensor |
Special sensor embedded within the brushless DC motor of an MDR used to provide motor rotor position feedback to the motor controller |
| IP54 |
The IP Code (International Protection Marking) specifies the device’s degree of resistance to intrusions, dust and water. IP54 certified device must be fully protected from splashed water, dust particles and completely protected from contact |
| LED |
Light Emitting Diode – In the context of this document, LED’s are used on the RaptorLinx-Ai-ST to provide visual indication of module status |
| Light / Dark Energized |
Term used to describe how the signaling output circuit of a photo-sensor is configured when it detects its reflected light. A photo-sensor that is light energized will activate its output circuit when it detects its reflected light. A dark energized photo-sensor will activate its output circuit when it does not detect its reflected light |
| M8 |
This is an industry standard 4 pin threaded connector used to connect a Senergy-Ai motor to the RaptorLinx-Ai-ST module |
| Modbus-TCP |
Adaptation of the well-established Modbus protocol for use over TCP/IP networks. It provides a standardized TCP interface that allows Modbus devices to communicate seamlessly over an Ethernet network. |
| MDR |
Motorized Drive Roller or Motor Driven Roller – Brushless DC motor and gearbox assembly integrated into a single conveyor roller |
| Normally Open / Normally Closed |
. Control logic terminology to define the state of the output of a Boolean “on” or “off” device. The term specifically describes the state of the output circuit when the device’s sensing circuit is un-energized. In the context of photo-sensors; a normally open wired sensor would have its output circuit energized when it detected its reflected light and its output circuit would be de-energized when it did not detect its reflected light. Conversely a photo-sensor wired normally closed would energize its output circuit when it did not see its reflected light and it would de-energize its output circuit when it did detect its reflected light |
| NPN / PNP |
Electronics term that indicates the type of transistor circuit used for a logical input or output for controllers. NPN devices will provide a common or ground connection when activated and a PNP device will provide a logic voltage connection when activated |
| Photo-sensor |
A device, mounted near the end of the conveyor zone to sense the presence of a carton on the zone |
| PI Regulator |
Proportional Integral control method used in motor control feedback to enhance response time and reduce steady state error |
| PLC |
Programmable Logic Controller – A wide variety of industrial computing devices that control automatic equipment |
| Profinet-IO |
Industry technical standard for data communication over Industrial Ethernet, designed for collecting data from, and controlling equipment in industrial systems, with a particular strength in delivering data under tight time constraints. The standard is maintained and supported by Profibus and Profinet International |
| PWM |
Pulse Width Modulation – a control scheme that utilizes high speed switching transistors to efficiently deliver power in a controlled fashion from the RaptorLinx-Ai-ST controller to MDR |
| RJ-45 |
Registered Jack Style 45 – Standard connector / receptacle format utilizing 8 pin connections. The typical standard for computer network cable connections |
| Retro-reflective / Reflex |
Term used to describe the two basic types of photo-sensors. Retro-reflective photo-sensors utilize a reflective target that must be aligned with the photo-sensor such that the light emitted by the photo-sensor is reflected back to it. ‘Reflex (or sometimes known as proximity) type photo-sensors emit light to be reflected back from an object located sufficiently close to the sensor. ‘For both types of photo-sensors, when they detect their reflected light source, their signaling output circuit changes state. |
| Slave Rollers |
A set of non-motorized conveyor rollers mechanically linked to an MDR. The MDR and slave rollers make up a physical zone. All of the slave rollers in a zone rotate at the same speed and direction as the MDR because of their mechanical linkage |
| TCP/IP |
Transport Control Protocol / Internet Protocol – IP is the protocol which oversees the transmission of information packets from device to device on an Ethernet network. TCP makes sure the packets have arrived and that the message is complete. These two protocols are the basic language of the Internet and are often referred to together as TCP/IP |
| Zone |
A basic (linear or curved) cell of the conveyor consisting of a set of slave rollers driven by one or more MDR’s and a single photo-sensor |
| ZPA |
Zero Pressure Accumulation – Term that describes the conveyor controls and mechanical scheme that will cause loads to queue on a conveyor in discrete zones such that loads do not touch each other |
