Designed for brushed DC and brushless DC motors up to 1,800W
continuous duty, the ESCON2 enhances control with features including field- oriented control (FOC) as well as acceleration and velocity feed forward. It also provides 4-quadrant operation, giving control over forward and reverse directions, as well as braking. The speed and torque controller is suitable for DC motors up to 3,600W maximum peak duty, and 30A continuous current up to 60A peak current. Building on its predecessor, this includes features that enhance control.
FOC functionality ensures smoother and more precise operation; acceleration and velocity feed-forward improves response times and control accuracy; and it features high control cycle rates, enabling rapid and accurate speed and torque adjustments to changing conditions. Further increasing control precision, ESCON2 can integrate with absolute encoders, as well as incremental encoders and Hall sensors. Furthermore, ESCON2 can function as a standalone controller with analogue and digital signal command capabilities, and it
can operate as a slave within a CANopen network,
enhancing connectivity for industrial applications. ESCON2 is available in a Module PCB format, enabling
direct OEM installation, and measures just 67m x 43 x 7.8mm. It is also available in a compact format featuring connectors already fitted,
ready for easy assembly, and in total measures just 93.5 x 46 x 41mm.
Once individually packed, the eggs go via
conveyor belt to the new plant where they are sorted into large pallet bins by flavour. These trays are then prepared via a robot either for mixing or to be picked up by a mobile robot for temporary storage. Once all the necessary flavours for making a mix are ready, the eggs are transported via funnels to precise positions on a wide conveyor so that all the flavours are lined up next to each other. At the end, the eggs re-enter a pallet bin where the different flavours are perfectly mixed. The first challenge was to ensure that the eggs are neatly distributed
when filling the pallet bins; the second challenge was positioning the hoppers over the conveyor on which the mix is assembled. Finally, a suitable drive had to be found for the gripper on the robot, which moves the 150kg pallet bins. The new Ergomix installation is located in an air-conditioned room.
To fill the pallet bins evenly, the conveyor belt feeding the eggs can be moved left and right via two timing belt shafts equipped with a servo motor and torsion shaft. An electric cylinder with spindle in the extension of the conveyor belt means it can also be extended forwards and backwards. This means the system can position itself to drop eggs at any position in the pallet bin. The controller receives feedback from the weighing cells under the bin and the flow rate of the supply so that it can determine exactly where in the bin there is still room. The positioning of the hoppers above the wide belt for mixing was also
realised with electric axes, which allow the positions to be automatically adjusted to the number of flavours which need to be brought together in a given mix. In addition, the gripper on the robot that moves the pallet boxes was equipped with a Festo ESBF electric cylinder with servo motor. All the CMMT servo motor controllers are housed in the electrical cabinet just outside the air-conditioned room. These communicate via Profinet with the PLC that controls the installation.
The smaller NEMA 08 and 11 sized motors have a choice of two current
ratings; and from size 14, a selection of stack lengths allow wide flexibility for drive and performance pairing. For motors from size 17, a choice of single as well as double shaft options in each current rating make encoder and/or brake fitting straightforward. The company also offers a wide range of compatible drives and controls, from component level to system engineered solutions, as part of its comprehensive application engineering service. Common specifications
throughout the new MSM range include Bi-polar wiring, IP40 protection and a maximum recommended temperature rise to 60˚C.
