Common Questions
Frequently Asked Questions
What is the difference between a VFD and a servo drive?
A VFD (variable frequency drive) controls AC motor speed by varying supply frequency and voltage. It is used for general speed control on pumps, fans, compressors, and conveyors where precise position control is not required. A servo drive operates in conjunction with a servo motor fitted with an encoder, closing a position and/or velocity feedback loop. Servo systems provide precise, repeatable position control with fast dynamic response — used in CNC machines, packaging equipment, robotics, and any application where accurate positioning is essential. VFDs are lower cost and simpler; servo systems offer far greater accuracy and dynamic performance.
What is the difference between inductive and capacitive proximity sensors?
Inductive proximity sensors detect metallic objects only, using an oscillating electromagnetic field that is damped when a metal target enters the sensing range. They are the most widely used sensor type in industrial automation due to their robustness and immunity to contamination. Capacitive proximity sensors detect any material — including plastics, liquids, wood, and bulk materials — by measuring changes in the electrostatic field. They are used where the target is non-metallic or where detection through container walls is required, such as level detection in plastic tanks.
What safety standards apply to machine safety products?
The two primary standards are ISO 13849 (Safety of Machinery — Safety-Related Parts of Control Systems), which defines Performance Levels (PLa–PLe), and IEC 62061, which defines Safety Integrity Levels (SIL 1–3). Both standards require a risk assessment to determine the required safety level, followed by selection of appropriate safety components. Light curtains, safety switches, safety relays, and safety controllers from our range carry the required certifications. Contact our team if you need help matching products to a specific Performance Level or SIL requirement.
What is an HMI and how does it differ from a PLC?
A PLC (programmable logic controller) is the control brain — it executes the machine programme, reads inputs from sensors and switches, and drives outputs to actuators and drives. An HMI (human-machine interface) is the operator display — it shows process values, alarm states, and machine status, and allows operators to adjust parameters and acknowledge faults. They are separate products that communicate over a serial or Ethernet connection. Some compact PLCs include a basic integrated display, but industrial applications typically use a dedicated HMI panel separate from the PLC.
What is RFID used for in an industrial setting?
Industrial RFID systems use read/write heads to communicate with data carriers (tags) attached to workpieces, pallets, or tools. Common applications include workpiece tracking on flexible manufacturing lines (the carrier stores the current build status and travels with the part), tool identification (verifying the correct tool is fitted before a machining cycle), and pallet routing in assembly and logistics systems. Industrial RFID operates at 13.56 MHz (HF) or other frequencies and is designed for the harsh electromagnetic environment of a production facility, unlike consumer barcode systems.
