Fanuc has released its Power Motion i-A CNC motion controller, which is designed to be easy to work with while providing the control requirements to drive energy consumption down.

New functions that simplify operation include enhanced position control, full remote control through an intelligent pendant, enhanced five-axis machining control, simple icon programming, status monitoring with auto-correction and safety functions to prevent machine collisions.

The Power Motion i-A CNC motion controller has now been enhanced with the ‘High Response Motion Control’ function, which allows multiple axes to be synchronised and positioned faster. Polling information for synchronisation is now available in cycles of 1msec, enhancing positioning and motion control.

Completely independent operation from the main CNC panel is now available using Fanuc’s Ipendant. The pendant’s touchscreen provides an identical image to that on the main panel screen, providing greater flexibility for programmers and ease of operation.

An energy monitoring function has been developed to display detailed energy consumption levels down to component level. Providing sufficient detail to optimise machining cycles, identified components can be programmed to idle or to increase machining speed to contribute to increased energy efficiency.

Key features and benefits

  • Controller offers enhanced five-axis machining control
  • Multiple axes can be synchronised and positioned faster
  • Independent operation from the main CNC panel is available thanks to the Ipendant
  • Safety machine operator panel is equipped with double contacts on all buttons and can communicate directly with the CNC system
  • System monitors and corrects any internal data transfer errors that can occur as a result of oil contamination, electromagnetic interference, vibration and other typical conditions common in industrial environments
  • Individual components set to idle become even more efficient with Fanuc’s Extremely Quick Restart feature

FANUC UK provides industrial automation solutions ranging from the supply of CNC controllers, robots, drilling machines, EDM and injection moulding machines through to the complete integration of factory automation systems.

Providing a single customer support portal for its three core businesses, FANUC comprises FA — CNC controllers, motors and drives; robotics — industrial robots and systems; robomachines — EDM, injection moulding and drilling machines.


FANUC’s FA business manufactures CNC controls, drive systems and laser systems. With a 65 per cent market share in the global CNC control sector, FANUC is the market leader. FANUC CNC is the controller of choice for the world’s leading machine tool manufacturers; continuously developing functionality sees FANUC CNC control being used in a wide range of applications — combining powerful control and high precision with unparalleled reliability.

FANUC servo drives and motors are well proven — aimed at the machine builder, they offer the widest range of high-performance compact designs.  The high availability and ease of maintenance together with world-class, energy-efficient designs make them the motors of choice for thousands of OEMs around the world.


FANUC’s robotics business manufactures the widest range of robots in the world for applications from micro-electronics assembly to the forging of precision aerofoils for jet engines — in industries as diverse as pharmaceutical and potato processing — and with maximum payloads from 1kg to 1,350kg. More than 280,000 FANUC robots are operating worldwide, with production currently geared to meet demands of 5,000 per month. FANUC robots are truly ‘out-of-the-box’ automation designed to be totally flexible and, with application-specific options, straightforward to integrate.


FANUC’s robomachine business manufactures Robodrill machining centres, Robocut EDM machines and Roboshot electric injection-moulding machines. Using FANUC components throughout, the robomachine business builds on the advanced technology, reliability, energy efficiency and innovation of its own controllers, drives and motors. With a focus on energy efficiency and high reliability, the robomachine business developed the first all-electric injection-moulding machines — Roboshot — changing the mould shop into a much cleaner and quieter environment.

Customer support

From initial sales contact with FANUC through the life of the product, FANUC provides one single contact point to make sure support is always at hand with up-to-date advice, genuine warranted parts and, whenever possible, obsolescence avoidance solutions that ensure the lifetime delivery of maximum efficiency.
